(Nexant) with support from Cascade Energy Engineering, Quantec, and Fazio Engineering to evaluate the next phase of program improvements for the FinAnswer® Express and Energy FinAnswer® energy efficiency programs. The primary objective of this analysis is to increase the level of cost-effective electrical energy and demand savings realized by the programs. Consistency across PacifiCorp’s service territories and with best practice programs offered by neighboring utilities is also a major consideration to simplify program implementation, reduce administrative costs, and avoid customer confusion in the marketplace. FinAnswer Express utilizes a streamlined incentive delivery process that incorporates prescriptive post-purchase incentives. FinAnswer Express targets established retrofit and new construction technologies for projects where the detailed custom engineering support and analysis provided by the Energy FinAnswer program is not necessary. The FinAnswer Express program is currently offered in PacifiCorp’s California, Idaho, Utah, and Washington service territories. This report presents the results of the FinAnswer Express analysis conducted for the Idaho service territory. Specifically, this effort reviewed the 65 current eligible program measures to confirm their appropriateness and update as necessary current incentive levels, costs, savings, and measure delivery mechanisms. In addition, Nexant reviewed 109 new measures for possible inclusion in the program based on the criteria that they are market ready technologies expected to result in cost effective, justifiable savings. Table ES-1 summarizes the eleven key measure categories and the number of current and potential new prescriptive measures reviewed as part of this process. Table ES-1.

Of the 109 evaluated potential new measures, Nexant recommends that 38 be incorporated into the program with a post-purchase incentive delivery model. Nexant has identified and summarized recommended evaluation and analysis methods for 5 of these measures to support streamlined processing and site-specific savings estimates of these measures when submitted under FinAnswer Express. Remaining measures are not recommended for prescriptive incentives or simplified analysis because of one or more of the following reasons:  Measures were found to be already established in the market (e.g. ENERGY STAR computers)  An existing energy efficiency program is already established in the target market (i.e. Irrigation Energy Savers)  Limited savings potential due to minimum efficiency requirements and current codes  Measures were too complex and customer site specific to identify simplified analysis and savings estimates while retaining an appropriate level of accuracy. Table ES-2 summarizes the recommendations from this analysis. Executive Summary FinAnswer® Express Market Characterization and Program Enhancements – Idaho iii Table ES-2.

Only measures with expected additional savings as compared to current program activity levels are included. Incremental utility administrative costs presented in Table ES-3 assume an implementation cost of $0.06 per new kWh/yr of gross customer energy savings with the exception of motors. Administration costs for Green Motor rewinds have been increased to $0.10/kWh to account for additional administrative costs necessary to coordinate with regional vendors that provide services to Idaho customers as well as cooperation with the Green Motors Practices Group. Administrative cost estimates also include:  Initial design costs to incorporate these changes of $15,000/yr, for the first year only  Incremental program evaluation costs of $15,000/yr  Incremental marketing costs of $ 50,000/yr for PacifiCorp to produce applicable program brochures, case studies, and other printed materials  Incremental PacifiCorp internal administrative costs of $10,000/yr Executive Summary FinAnswer® Express Market Characterization and Program Enhancements – Idaho v Table ES-4.

FinAnswer® Express Market Characterization and Program Enhancements – Idaho 1-1 Section 1 Introduction 1.1 OVERVIEW In December of 2007, PacifiCorp retained Nexant, Inc. (Nexant) with support from Cascade Energy Engineering, Quantec, and Fazio Engineering to evaluate the next phase of program improvements for the FinAnswer® Express and Energy FinAnswer® energy efficiency programs. The primary objective of this analysis is to increase the level of cost-effective electrical energy and demand savings realized by the programs. Consistency across PacifiCorp’s service territories and with programs offered by neighboring utilities is also a major consideration to simplify program implementation, reduce administrative costs, and avoid customer confusion in the marketplace. FinAnswer Express is a streamlined version of PacifiCorp’s Energy FinAnswer program, providing prescriptive cash incentives for common energy efficiency measures currently including lighting, premium efficiency motors, and high-efficiency HVAC equipment. FinAnswer Express targets straightforward equipment upgrade projects or projects when customers do not need the additional technical services provided under the Energy FinAnswer program. Customers receive incentives directly using a post-purchase incentive application. Reported costs and savings vary between actual, deemed based on project specific variables (e.g. deemed energy and demand savings as a function of horsepower for premium efficiency motors), or deemed simply on the measure type. Table 1-1 summarizes the current FinAnswer Express program. Table 1-1.

Specifically, this effort reviewed the sixty-five (65) existing measures included in the program shown in Table 1-1 to confirm the appropriateness and update as necessary current incentive levels, costs, savings, and measure delivery mechanisms. In addition, Nexant Introduction FinAnswer® Express Market Characterization and Program Enhancements – Idaho 1-2 reviewed one hundred nine (109) new measures for possible inclusion into the prescriptive delivery component of the program based on the criteria that they are market ready technologies expected to result in cost effective, justifiable savings. 1.2 APPROACH TO WORK Analysis activities utilized a systematic approach to evaluate each identified energy efficiency measure. The approach focused on using existing data resources with limited primary data collection efforts. Figure 1-1 on page 1-3 outlines the general methodology. A brief description of each key activity follows:  Measure/Technology Review. Initial analysis efforts for each measure consisted of a review of existing data sources to compile cost and savings data. Each measure investigated made use of a core set of resources, listed below in Table 1-2. For certain technologies, additional resources provided supplemental measure information. These resources are noted in the individual measure write-ups provided in Sections 2-12 of this report. Section 14 provides a complete list of all resources. Table 1-2.

Nexant conducted a review of existing energy efficiency programs to identify prescriptive incentive programs that covered measures investigated as part of this work. These efforts focused on program offerings from major utilities and energy efficiency organizations with service territories close to PacifiCorp (summarized in Table 1-3). Included in the analysis are additional prescriptive programs familiar to Nexant or identified through other review activities. These resources are noted in the individual measure write-ups provided in Sections 2-12 of this report.

To assess the appropriateness of current baseline assumptions for existing measures and to help establish baselines for potential new prescriptive measures, analysis efforts included a review of applicable code requirements. Review efforts focused on both state and federal codes. Review activities also included current code requirements and planned future code updates where available. In Idaho, the 2006 International Energy Conservation Code (IECC 2006) is the current code for non-residential facilities.  Vendor Identification and Input. Equipment manufacturers, distributors and dealers of investigated measures were contacted informally to confirm measure cost and savings data collected as part of the above activities. In some cases, vendors also provided input on local activity and the expected market response to prescriptive incentives for high- efficiency measures. In each of Sections 2-12 of this report are lists of vendors for the applicable measure category.  Identification of Candidate Prescriptive Measures. Nexant evaluated each of the one hundred nine (109) new candidate technologies to identify those that met the established prescriptive measure criteria. These measures were then more fully analyzed as described in the remaining steps outlined below. For measures not recommended for prescriptive incentives at this time, Nexant assessed whether a simplified analysis procedure was available or could be readily prepared to help expedite the review activities associated with processing the measure under either FinAnswer Express or Energy FinAnswer.  Establish Baseline. Baseline efficiencies were established for new potential prescriptive measures. Existing federal or state code requirements, or those planned and expected to be in effect through 2010, were typically used as the baseline value. For measures where no code requirement existed, current industry practices identified during the evaluation activities were used. For current FinAnswer Express measures, this step consisted of reviewing the appropriateness of current baseline assumptions. Introduction FinAnswer® Express Market Characterization and Program Enhancements – Idaho 1-5  Set Minimum Efficiency Requirements. Recommended minimum efficiency levels for potential new prescriptive measures were established based on findings from the evaluation activities. In general, minimum efficiency requirements were set to match current market levels established by others such as the Consortium for Energy Efficiency (CEE) or Energy Star to leverage existing market awareness. For current FinAnswer Express measures, this step consisted of reviewing the appropriateness of current minimum efficiency requirements.  Determine Deemed Unit Cost and Savings. Estimated incremental cost and savings values were then determined for new prescriptive measures based on the proposed minimum efficiency requirements and associated baselines. For current FinAnswer Express measures, this step consisted of reviewing the appropriateness of current deemed costs and savings values.  Define Incentive Delivery Mechanism. For potential new prescriptive measures, a recommended incentive delivery mechanism was identified. To maintain consistency and help minimize program administrative costs, a post-purchase application and incentive delivery process was the default approach. Specifically, the approach includes a flexible post-purchase application process that allows customers to receive incentives directly, but also allows for reassignment of incentives, providing vendors the opportunity to credit eligible incentive amounts to their customers at the time of purchase and then receive reimbursement from PacifiCorp. For current FinAnswer Express measures, this step consisted of reviewing the appropriateness of the current incentive delivery mechanism.  Identify Incentive Level. Proposed incentive levels for new prescriptive measures were identified through an iterative process that considered the following factors: ― Estimated incremental customer costs ― Incentive levels offered by other utilities for similar measures ― Feedback from vendors ― The value of savings achieved by the measure For current FinAnswer Express measures, this step consisted of reviewing the appropriateness of current incentive values.  Estimate Program Level Impacts. For potential new prescriptive measures, or when a significant change in an existing prescriptive measure was recommended, estimates of the incremental program savings and customer costs were prepared. Nexant estimated the measure-level participation rates from a variety of sources, including referenced DSM market potential studies, program participation estimates filed by other utilities for similar measures, and realized values from existing programs. Introduction FinAnswer® Express Market Characterization and Program Enhancements – Idaho 1-6 1.3 REPORT ORGANIZATION The balance of this report presents results from the analysis approach outlined above. Specifically:  Sections 2-12 contain detailed summaries of the measure level analysis results for the respective measure categories.  Section 13 presents the estimated incremental savings and costs values associated with changes recommended for current and new prescriptive measures in the program  Section 14 includes a listing of references used to complete this evaluation  Several appendices contain additional information and findings described in the main body of the report 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-1 Section 2 Appliances 2.1 APPLIANCE CATEGORY OVERVIEW A new category of appliance measures has been added to the FinAnswer Express program to help increase consistency among PacifiCorp’s energy efficiency programs. Specifically, the Home Energy Savings program offers residential customers incentives for the purchase and installation of a number of qualifying appliances, including:  Ceiling Fans  Clothes washers  Dishwashers  Refrigerators  Room Air Conditioners  Water Heaters For non-residential customers, however, there is currently no companion program for the purchase of these same qualifying appliances for use in non-residential facilities. To expand this measure category, additional commercial grade appliances were included in the analysis. Please note that dishwashers and refrigerators were evaluated as part of the Food Service category presented in Section 6 of this report. As this is a new category of measures for the FinAnswer Express program, there were no existing measures revisited as part of this effort. Table 2-1 summarizes the specific appliance measures evaluated in this section. Table 2-1. Evaluated Appliance Measures Existing FinAnswer Express Appliance Measures Potential New FinAnswer Express Appliance Measures None Ceiling Fans (Residential used in Commercial) Clothes Washers (Commercial) Clothes Washers (Residential used in Commercial) Room Air Conditioners (Residential used in Commercial) Water Heaters (Commercial) Water Heaters (Residential used in Commercial) 2.1.1 Appliance Category Descriptions Following are more detailed descriptions of the individual appliance measures identified above in Table 2-1.  Ceiling Fans: The definition of a ceiling fan was taken from the Code of Federal Regulations: “Ceiling fan means a non-portable device that is suspended from a ceiling for circulating air via the rotation of fan blades.” (10 CFR part 430.2). This definition is consistent with that Section 2 Appliances 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-2 used by ENERGY STAR. Note that under the 2007 California Appliance Efficiency Regulations, this definition is augmented with the language “…no more than 45° from horizontal.”  Clothes Washer (commercial): The definition of commercial clothes washers was taken from the Code of Federal Regulations: “Commercial clothes washer means a soft-mounted front-loading or soft-mounted top- loading clothes washer that 1) has a clothes container compartment that for horizontal-axis clothes washers, is not more than 3.5 cubic feet and for vertical-axis clothes washers is not more than 4.0 cubic feet; and 2) is designed for use in applications in which the occupants of more than one household will be using the clothes washer, such as multi-family housing common areas and coin laundries; or other commercial applications” (10 CFR part 431.152). This definition is consistent with that used by ENERGY STAR and the current Washington and California state appliance standards.  Clothes Washer (residential): The definition of residential clothes washers was taken from the Code of Federal Regulations: “Clothes washer means a consumer product designed to clean clothes, utilizing a water solution of soap and/or detergent and mechanical agitation or other movement, and must be one of the following classes: automatic clothes washers, semi-automatic clothes washers, and other clothes washers” (10 CFR part 430.2).  Room Air Conditioner: The definition of room air conditioners was taken from the Code of Federal Regulations: “Room air conditioner means a consumer product, other than a “packaged terminal air conditioner,” which is powered by a single phase electric current and which is an encased assembly designed as a unit for mounting in a window or through the wall for the purpose of providing delivery of conditioned air to an enclosed space. It includes a prime source of refrigeration and may include a means for ventilating and heating” (10 CFR part 430.2). Note that the California Appliance Efficiency Regulations uses a slightly different definition: “Room air conditioner” means a factory-encased air conditioner that is designed (1) as a unit for mounting in a window, through a wall, or as a console, and (2) for delivery without ducts of conditioned air to an enclosed space” (CEC 2007).  Water Heater (commercial): Commercial electric water heaters were defined analogous to residential water heaters (see next measure), with the distinction that commercial water heaters have an electric input >12 kW compared to <12 kW for residential units. This analysis only considered storage type units – instantaneous and heat pump water heaters were not evaluated. This definition is consistent with the breakpoint used in federal minimum efficiency requirements, described in greater detail in Section 2.4. Section 2 Appliances 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-3  Water Heater (residential): For this analysis, the definition of a residential electric water heater was adapted from the Code of Federal Regulations to be “a product which utilizes oil, gas, or electricity to heat potable water for use outside the heater upon demand, including (a) storage type units which heat and store water at a thermostatically controlled temperature, including … electric storage water heaters with an input of 12 kilowatts or less…” (10 CFR part 430.2). Instantaneous and heat pump water heaters were not considered in this evaluation. 2.2 APPLIANCE MEASURE TECHNOLOGY REVIEW Table 2-2 identifies the key informational resources utilized to conduct the appliance measure technology review. Detailed measure cost and savings data obtained from these resources are provided in Appendix B. Table 2-2.

Currently, ENERGY STAR rates four of the six measures evaluated with estimated customer cost and savings data available for each technology. The ENERGY STAR criteria for Clothes Washers was revised in 2008 and includes more stringent eligibility criteria becoming effective on July 1, 2009 and again on January 1, 2011.. As of December 2008, ENERGY STAR was not evaluating any revisions to the current versions of these four specifications. The two measures not currently covered by ENERGY STAR are the commercial and residential water heaters. ENERGY STAR released a final specification for residential water heaters on April 1, 2008 (effective on January 1, 2009), but it will not address electric units. According to the final criteria analysis released by ENERGY STAR: Both electric-resistance storage and tankless water heaters present limited individual energy savings potential. Energy Factor is the ratio of useful energy output to the total amount of energy delivered to the water heater. The perfect electric-resistance water heater could not exceed an Energy Factor of 1.0 due to this technology’s physical Section 2 Appliances 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-4 limitations. The best electric-resistance storage water heaters achieve an Energy Factor of 0.95 and the best electric-resistance tankless water heaters achieve an Energy Factor of 0.99. This technology has little to no room for improving its current energy savings. A savings of 4.8% and 8.7% is not significant and does not offer meaningful differentiation in accordance with the ENERGY STAR guiding principles. In addition, electric resistance technology has nearly maximized its energy savings potential. Given current and potential energy savings, electric resistance water heating technology is not under consideration for ENERGY STAR. (ENERGY STAR Residential Water Heaters: Final Criteria Analysis, April 1, 2008) There was a significant lack of information found on commercial electric storage water heaters. A review of the Gas Appliance Manufacturers Association (GAMA) Consumers' Directory of Certified Efficiency Ratings for Water Heating Equipment found 39 certified units with only about half appearing to meet the federal minimum efficiency requirements (GAMA 2008). One other key finding from the technology review was a variation in the efficiency specifications between ENERGY STAR and CEE. Table 2-3 highlights these differences. It should be noted that the revised ENERGY STAR specification for Clothes Washers aligns ENERGY STAR with CEE Tier 1 requirements on July 1, 2009 and CEE Tier 2 criteria on January 1, 2011. Table 2-3.

From 2004 through 2006, this project sought to increase the residential market share of high-efficiency clothes washers (MEF of 1.8 or greater) across NEEA’s four-state territory (WA, OR, ID and western MT) through coupons, promotional activities, and field service support for retailers and manufacturers. This program is now part of the larger Northwest ENERGY STAR market transformation initiative, using the collective influence of participating utilities to achieve the same goal. The key finding from the utility DSM program review is the absence of prescriptive offerings for electric commercial water heaters. This trend was reinforced when the search umbrella was expanded to a nationwide search using Google (www.google.com) and the Database of State Incentives for Renewables & Efficiency (www.dsireusa.org). In both instances where a prescriptive incentive was offered for ceiling fans, eligibility requirements mandated units with the integrated or attachable ENERGY STAR light fixture. A detailed summary of the utility incentives and qualification requirements can be found in Appendix C. In addition to the utility information summarized in Table 2-4, detailed cost and savings data for three of the six appliance measures was obtained from PacifiCorp’s 2008 Home Energy Savings program in Idaho. This information is summarized in Table 2-5. Section 2 Appliances 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-6 Table 2-5.

The Act requires DOE to complete a rulemaking for revised standards for clothes washers by 2012. The Department of Energy (DOE) has commenced a rulemaking to amend the existing energy conservation standards for residential water heaters. Under the current schedule, a final rule is anticipated by March, 2010. A similar effort is underway for room air conditioners with a final ruling anticipated by June, 2011. Depending on the timing and changes reflected in these rulings, adjustments to the estimated savings, costs, and incentives may be necessary for these two measures. The minimum efficiency code requirements for appliance measures summarized in Table 2-6 represent the applicable code requirements in PacifiCorp’s California, Idaho, Utah, and Washington service territories with the following exceptions:  IECC 2006 specifies a maximum standby loss for electric commercial water heaters of 1.73*Vr+155 (Btu/hr) where Vr is the rated volume (gallons). In some cases, this efficiency requirement is more stringent than the Federal minimum efficiency requirement.  The California Appliance Efficiency Regulations provides additional minimum efficiency requirements for commercial water heaters with an input to volume ratio ≥ 4,000 Btu/gallon (see Table 2-7). Also, the California Appliance Efficiency Regulations specifies maximum water factors for residential clothes washers that are more stringent than federal code (see Table 2-8). These specifications are currently pre-empted by federal standards. The California Energy Commission’s petition for a waiver from Federal pre-emption of Califorina’s water conservation standards for residential clothes washers was denied on December 28, 2006. A lawsuit to settle the matter between the State of California and the Federal Government is currently proceeding in the Ninth Circuit Court of Appeals.

Table 2-10. Representative Idaho Appliance Vendors Vendor Phone Number Home Depot (208) 542-2520 Lowes (208) 542-9030 Northgate Appliance (208) 524-2122 Section 2 Appliances 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-10 These vendors provide products for all of the appliance measures except commercial washers. Table 2-11 contains the contact information of two identified suppliers of commercial washers. Table 2-11. Idaho Commercial Laundry Vendors Vendor Phone Number Thompsons, Inc. (800) 881-5179 American Meter and Appliance (800) 562-2858 As part of this evaluation, Nexant surveyed these vendors and others across PacifiCorp’s service territories to identify current market awareness and trends associated with the evaluated measures. Some key feedback received includes the following:  Several Home Depot representatives from different states remarked that about three quarters of the clothes washers they have for sale are ENERGY STAR models and that the majority of people looking for a new clothes washer are looking for one that is energy efficient.  Commercial washer dealers echoed many of the findings that the residential washers mentioned. One company mentioned that all of the products offered are ENERGY STAR rated, adding that most customers “don’t ask about ENERGY STAR, but we tell them.” Another vendor stated that an incentive would be helpful in enticing people to buy models that are more energy efficient than the ENERGY STAR rated models (such as CEE Tier 2 or 3).  Another commercial washer vendor in Utah stated that in some jurisdictions, customers looking to establish new laundromats are assessed an “Impact Fee” for increased water and sewer usage. This fee is significant relative to the cost of machinery and does not depend on the efficiency of the equipment being considered, rather solely on the capacity considered to be installed.  General consensus among respondents is that sales of water heaters continue to be mostly on an emergency basis. Customers’ primary concern with water heaters is price and availability, but vendors did mention that customers will buy a high efficiency model if the price difference is minimal. The vendor survey instrument and additional vendor responses are provided in Appendix A. 2.6 APPLIANCE MEASURE PRESCRIPTIVE RECOMMENDATIONS Four of the six evaluated appliance measures are recommended for post-purchase prescriptive incentive delivery under the FinAnswer Express program. These measures are all expected to be installed upon equipment failure or as part of new construction opportunities. Therefore, no modifications are recommended to the baseline, incentives, or estimated savings between retrofit and new construction projects. Section 2 Appliances 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 2-11 Post-purchase prescriptive incentives are not recommended for commercial water heaters because:  Neither ENERGY STAR nor CEE recommend a minimum efficiency requirement, most likely due to the limited savings potential beyond current code requirements,  No other electric utilities appear to be offering a prescriptive incentive program for this measure, and  Limited models are available. While >12 kW commercial water heaters are not expected to be a high-volume measure, a simplified analysis for use in processing custom applications can be found in Section 2.9. To achieve parity with the Home Energy Savings program in Idaho, it is recommended that incentives not be offered through the FinAnswer Express program for Room Air Conditioners (Residential used in commercial). Eligibility requirements, estimated savings, and incentives for the recommended measures were established to be consistent with PacifiCorp’s Home Energy Savings. A post-purchase customer incentive delivery mechanism, with the flexibility to allow customer assignment of incentives to vendors if desired, is recommended. In addition, it is recommended that the established Trade Ally network for the Home Energy Savings program be utilized to support the delivery of these measures to the non-residential market. Table 2-12 contains a summary of the appliance measure prescriptive recommendations. Additional information on recommended baselines, measure eligibility requirements, cost, savings and incentives is provided in the balance of this section. Table 2-12.

Corresponding cost estimates for commercial clothes washers were based on information obtained from PG&E. Estimated energy savings are based on the residential clothes washer savings multiplied by the ratio of estimated annual commercial loads versus residential loads obtained from ENERGY STAR. Home Energy Savings program estimates for clothes washers incorporate a weighting factor adjusting savings to account for customers with gas water heating or gas dryers. As such, any Rocky Mountain Power customer is eligible to apply for incentives for clothes washers, regardless of type of fuel used to supply hot water or dryer heat. Table 2-14 summarizes the key measure information for the recommended appliance measures.

Due to the limited savings potential for residential water heaters, removal of this particular measure from the program may be necessary following any further increase in minimum efficiency requirements. In addition, measure eligibility requirements, savings, and incentives for recommended prescriptive appliance measures may need to be adjusted to reflect more stringent baseline requirements, following changes and increases in recommended energy efficiency tiers by ENERGY STAR, CEE, and other recognized industry leaders. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-1 Section 3 Compressed Air 3.1 COMPRESSED AIR OVERVIEW A list of compressed air measures were investigated for suitability in the FinAnswer Express program. The investigated measures are listed in Table 3-1. Table 3-1. Evaluated Compressed Air Measures Existing FinAnswer Express Compressed Air Measures Potential New FinAnswer Express Compressed Air Measures None Engineered Nozzles Low Pressure-drop Filters Pressure/Flow Controllers Purge Control on Desiccant Dryers Receiver Capacity Addition Refrigerated Cycling Dryers VFD Controlled Compressor Zero Loss Condensate Drains Outside Air Intake Automatic Bag House Filter Cleaner Controls Waste Heat Recovery 3.1.1 Compressed Air Measure Descriptions Following are more detailed descriptions of the measures listed in Table 3-1.  Engineered Nozzles: Compressed air is commonly used to remove solids or liquids from a surface, cool an object, or move parts down a path. These are considered “open blowing” applications. When open compressed air blowing is used, it often takes the form of copper tubing, bent to direct the compressed air where it is needed. Sometimes the tip of the tubing is crimped to create a simple nozzle. Other times holes are drilled into a pipe to create a long impact area. In most instances a manual valve and/or pressure regulator is installed ahead of the nozzles to control the flow. For applications that require open compressed air blowing, using an appropriate engineered nozzle will reduce compressed air consumption. Virtually all open blowing applications will be more effective and use less compressed air if an engineered nozzle is applied. Greater or equal impingement forces can be achieved with less air consumption. Some engineered nozzles have multiple openings and are designed to entrain surrounding air to increase their effectiveness. Open blowing applications and the use of engineered nozzles are very sensitive to site details. There are often several different ways to accomplish the same task using varying amounts of compressed air. There may also be non-energy benefits to engineered nozzles, such as reduced noise levels and increased safety. Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-2 Reducing air consumption saves energy at the air compressor. If the compressor has poor part load performance, such as with an inlet modulating screw compressor, very little energy may be saved (~.05 kW/cfm). If the compressor has efficient part load performance, such as a variable speed screw compressor, the energy savings can be significant (~.18 kW/cfm). In some multiple compressor installations, a modest reduction in air demand may allow a compressor to turn off which can save a great deal of energy. A nozzle may be an “engineered” and machined part, but still consist of a simple orifice with only marginal improvement over the performance of a copper tube. In situations where copper tube or drilled pipe is used, any nozzle will be an improvement. In situations that already have basic nozzles, there may be several better nozzles that can accomplish the same task using less air. In summary, “Basic” nozzles and “high efficiency” nozzles represent two points on a continuum as opposed to discrete categories. Open blowing is used varying fractions of the time. On one extreme, a blow gun may be installed by a particular machine, but is only used once every few weeks for 5 or 10 seconds. On the other extreme, air may be blown continuously as part of a manufacturing process. These applications may use the same nozzles, but have vastly different potential for energy savings. Due to the wide variety of nozzle types, the fact that each has unique usage characteristics and applications, the difficulty generating a baseline energy consumption estimate and the lack of a suitable definition or eligibility requirement for “high efficiency” nozzles, a prescriptive incentive program using deemed savings and costs is not recommended for engineered nozzles at this time and is not further explored in this analysis.  Low Pressure-Drop Filters: Coalescing filters are designed to remove solids and aerosols from compressed air. Aerosols coalesce into liquids that fall to the bottom of the filter body and are removed through a drain to a condensate system. Standard coalescing filters have the following general properties: • Filter housing is fairly small, • Filter housing is usually supported by the compressed air pipe, and does not rest on the floor, • Element life is typically 6 to 12 months, • Elements are fairly dense and thin, about ¼” thick, • Filters are less effective at low velocity/flow and many standard coalescing filters lose effectiveness at low air velocity, and • Moderate pressure drop (new coalescing filters may have losses of 3 psi at rated flow and pressure drop at element change may be 4 to 6 psi). Loose-packed, deep-bed coalescing filters have lower pressure drop, longer element life and perform the same task as standard coalescing filters but have the following differences: • Filter housing is much larger, usually resting on the floor, • Element life is typically 5 years or longer, ranging up to 15 years, • Elements are thicker, about 2” thick, • Filtration remains effective at low velocity, Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-3 • More expensive than standard coalescing filters, and • Low pressure drop (manufacturers generally guarantee 1 psi or less pressure drop at rated flow when new (often the pressure drop is less than 0.5 psi) and pressure drop at element change is 2 to 3 psi). Higher filter pressure losses force the customer to raise the compressor pressure settings to achieve the same air pressure at the users. Once pressure settings are raised, they are rarely lowered. At higher discharge pressures, compressors consume more energy. Some low pressure drop filters are installed without adjusting the compressor settings to take advantage of the reduced pressure loss of the filter. In this situation, energy use may actually increase due to higher line pressures and increased air consumption by leaks and unregulated users.  Pressure/Flow Controllers: Pressure/flow controllers are used to maintain the pressure in the distribution piping at a steady level, while allowing the compressor discharge pressure to vary. This reduces artificial demand, compressor capacity, and compressor power. Artificial demand is the extra compressed air consumed by leaks and unregulated users when the line pressure is higher than it needs to be. For example, if a system needs 80 psig line pressure to function effectively, but the line pressure is 90 psig, all of the leaks and unregulated users will consume more air. This increases the compressor capacity and power. In medium and large compressed air systems, increasing the line pressure from 80 to 90 psig can cost another 100 hp or more of compressor power. Using a flow controller to maintain the line pressure at the minimum acceptable pressure saves compressor power. Most flow controllers are able to maintain the downstream pressure to within 2 psi of the setpoint or better, sometimes less than 1 psi deviation. To be effective, compressed air must be stored at higher pressure in receiver tanks ready to be released through the flow controller when the demand changes. Some flow controllers are electronically actuated with user-adjustable tuning. Somewhat less expensive are pneumatically powered flow controllers. These may require a minimum differential to operate properly. For example, if you want to maintain 80 psig downstream pressure, the upstream pressure must be at least 85 psig. On some smaller single compressor systems, a low cost regulator is used as a flow controller. These do not have precise downstream pressure control. With a flow controller, the compressor discharge pressure may be raised which can offset some of the energy savings. Flow controllers can be very effective when intelligently applied on large multiple compressor systems. In these systems, the air stored at elevated pressure in the tanks can allow the system to ride through a temporary increase in compressed air demand without starting an additional compressor. On smaller single compressor systems, the energy benefits are less clear, because the compressor pressure settings must be raised. With variable speed compressors, flow controllers are generally not needed except in special circumstances. Due to the fact that pressure/flow controllers are most useful and more commonly installed on larger compressed air systems (>100hp) which usually have specific operating characteristics, this measure is not recommended for a Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-4 prescriptive incentive program targeted at smaller compressed air systems and it not explored further as part of this analysis.  Purge Control on Desiccant Dryers: Desiccant dryers purge compressed air as part of the desiccant regeneration process to help regenerate or purge the dryer. Basic dryer controls use a fixed timer to regenerate the dryer, regardless of the actual moisture load. Purge saving controls can be used to measure the moisture load on the dryer and delay dryer purging until necessary. When purging is delayed, the air compressors operate at reduced capacity and reduced power for a longer period of time. The amount of energy savings depends on the part load efficiency of the compressors. When purchasing a new dryer, the customer often has the option of adding purge saving controls. The cost of adding purge saving controls is usually a fixed amount, regardless of the size of the dryer. This makes it very cost effective for large dryers, but less cost effective for smaller dryers. Different dryer manufacturers have different control offerings. From some manufacturers, purge saving controls are standard within some sizes and types of dryers. Other manufacturers offer better and best purge saving controls, which use different methods to calculate moisture load and delay dryer purging. The methods used to determine moisture load vary. Some dryers use dewpoint sensors on the air exiting the dryer and regenerate the tower when the dewpoint hits a certain level. Others sense the dewpoint part way through the desiccant bed. Others don’t measure dewpoint directly at all, but measure dryer load using other sensors and techniques. Failed dewpoint sensors are commonly observed in the field. When a sensor fails, the operator can put the dryer into a timer based regeneration mode, which regenerates the dryer on a timed basis without regard to moisture load. In timer mode, the dryer purges the maximum amount of compressed air. The dryer works just fine in timer mode and replacement sensors can cost several hundred dollars, so often the dryer remains in this mode for years. A great deal of energy could be saved by simply replacing all of the failed dewpoint sensors and putting existing dryers back into the purge saving mode. It is possible to retrofit most desiccant dryers with dewpoint controls. However, few vendors are interested in this as it involves researching the existing dryer, custom installation, integrating the purge controls with the existing dryer controls, and it is not a large sale for the vendor.  Receiver Capacity Addition: Adding receiver volume to a compressed air system may allow the system to operate at lower pressure, slow compressor cycling, and allow for better sequencing of compressors. Virtually all new compressed air systems are sold with some compressed air storage. On small systems, the compressor may be tank-mounted. On medium and large systems the tanks are installed separately. Tanks can be located at the compressor discharge, after the filters and dryer, and near users. A tank can also be dedicated to a particular user to allow it to function more reliably or to allow it to function at lower line pressures. Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-5 The clearest case where receiver capacity directly impacts energy consumption is on compressors that use inlet modulation due to the lack of receiver tank capacity. Adding a receiver tank and changing the compressor to operate in load/unload mode can have dramatic energy savings. This is among the fastest payback compressed air energy projects. Most compressor manufacturers do not sell compressors with only inlet modulating controls, and most compressors are able to operate load/unload with standard factory controls. The notable exception is Rogers Machinery which still sells modulation only compressors. Rogers Machinery has a large market share in PacifiCorp’s Washington and California service territories, but little or no presence in Rocky Mountain Power service territory. The classic application for additional receiver volume is a system using load/unload controls with marginal receiver volume. Adding receiver volume can reduce the average compressor power. When the compressor unloads, the power does not instantly fall all the way to the fully unloaded power, but decays over a period of time. If the receiver capacity is relatively small, the compressor may have to load again before the compressor has reached the fully unloaded power. When older design oil injected screw compressors unload, the power falls slowly, taking 60 seconds or more to reach minimum power. On many newer design compressors the power falls much more quickly. With newer design compressors, there is less energy benefit to adding receiver volume. There are various reasons and ways to apply receiver tanks to compressed air systems, including many applications that are not discussed here. Adding receiver tank volume without a thorough analysis of the existing sytem is likely to save little or no energy.  Refrigerated Cycling Dryers: At reduced capacity, cycling refrigerated dryers use less energy than non-cycling dryers. Non-cycling refrigerated dryers use a nearly constant amount of energy, regardless of compressed air flow. Cycling refrigerated dryers use energy nearly in proportion to the compressed air flow. Thermal mass cycling refrigerated dryers cool a thermal mass (usually a glycol/water mixture), and then shut-off until the thermal mass warms up due to compressed air flow and temperature. When the air flow and air temperature is low, the dryer will be off most of the time. Some thermal mass cycling dryers operate a pump continuously to circulate the thermal mass. Some cycling dryers cool only a metal heat exchanger as the thermal mass. This type of cycling dryer has less energy savings at reduced capacity. Non-cycling dryers run continuously, regardless of air flow. Some manufacturers offer non-cycling dryers only in small sizes. In larger sizes all of the offered products may be cycling or thermal mass cycling dryers. Other manufacturers offer both cycling and non-cycling dryers for all size ranges. Very large refrigerated dryers (above ~3,000 SCFM) are all likely to have good part load performance. Some cycling dryers can be switched to operate in non-cycling mode on the control panel. Most of the time dual mode dryers are found operating in the less efficient non-cycling mode. This is likely because a dryer in non-cycling mode is always making noise assuring the operator that it is functioning. Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-6  VFD Controlled Compressor: Variable speed oil injected screw compressors are more efficient than fixed speed oil injected screw compressors at medium and low capacity. At full capacity, fixed speed oil injected screw compressors are fairly efficient but at reduced capacity, their efficiency can suffer dramatically. Screw compressors using inlet modulation consume about 70% power at 0% capacity. Variable displacement controls are quite efficient between 70% and 100% capacity, but below this capacity the efficiency drops quickly. Variable displacement controls are also frequently out of adjustment. Load/unload operation can be efficient across a range of operation depending on the fully unloaded power, compressor settings, and receiver tank capacity. In Cascade Energy’s engineering judgment, if the part load efficiency of all compressors in PacifiCorp territory were blended based upon their relative abundance, the average power at 0% capacity is about 50% of full load power. Variable speed oil injected compressors are slightly less efficient at full load due to variable frequency drive (VFD) losses and air end speed issues, but are significantly more efficient than other control methods at medium and low load. Many variable speed compressors are able to cycle on and off during periods of low load, providing excellent efficiency at very low capacity. In the field of oil-free screw compressors, variable speed compressors have a much smaller benefit over fixed speed compressors. Fixed speed oil free screw compressors operate load/unload, but when they unload, there is no sump to depressurize, so the power falls to the minimum power almost instantly (about 1 second). The unloaded power of oil free screw compressors is also quite low, typically about 20% of full load power. Given this efficient baseline part load performance, oil free variable speed applications were excluded from consideration for inclusion in the FinAnswer Express program.  Zero Loss Condensate Drains: Liquid water must be removed from the compressed air system. Timer type drains vent some compressed air and are frequently adjusted very conservatively, wasting compressed air. Zero loss drains do not consume compressed air. A low cost way to remove liquid water from a compressed air system is a timer drain. These have two dials where the drain frequency and duration are set. In the field, they are usually set very conservatively, draining water for 1 to 3 seconds, but venting air for an additional 5 to 20 seconds. When the drain actuates, it also causes a large jump in compressed air demand. This can force an additional compressor to start in some circumstances. Zero loss drains remove the water without venting compressed air. They can be electronically or pneumatically actuated. Zero loss drains can be installed improperly, so some care must be taken to follow the manufacturer recommendations.  Outside Air Intake: Original Definition: Air compressors may produce greater mass flow when cooler air is supplied to the compressor inlet. There is also a slight increase in compressor efficiency with cooler inlet air. Automatic controls can determine if the outside air or compressor room is cooler, and then supply the air compressor with inlet air from the cooler location. Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-7 Cascade Findings: Automatic controls to select the inlet air source based on compressor room and outside air temperatures are extremely rare. An updated definition for this measure was used. Updated Definition: Compressors drawing cooler outside air operate with slightly greater efficiency. This is accomplished by ducting air from outside the compressor room to the inlet of the compressor. Screw compressors trap a fixed volume of air and reduce its volume. When the inlet air is hotter, there are less air molecules in the trapped volume, and the mass flow rate of the compressor is reduced. Compressor room temperature control is generally not a high plant priority, and many compressor rooms are neither heated nor cooled. When using cooler inlet air, the full load capacity of the compressor increases. This allows the compressor to operate at a lower percent capacity to produce the same flow rate. If the compressor has good part load efficiency, then energy will be saved. If the compressor has poor part load efficiency, then the savings may be negligible. Large centrifugal compressors virtually always draw air from outside the compressor room. This is also generally true for large air cooled screw compressors. It is much less common for medium and small screw compressors.  Automatic Bag House Filter Cleaner Controls: Bag houses commonly use a fixed timer to pulse compressed air to clean the filters. Automatic controls can detect the filter condition and clean the filters only as needed, reducing compressed air consumption. A Photohelic® pressure switch can start the compressed air pulsing cycle when the pressure drop across the filters reaches a high level, and stop the pulsing when the pressure drop reaches a low level. Other similar systems do not use a Photohelic® switch, but accomplish basically the same thing. This type of control is available as a factory upgrade on most bag houses. It is essentially standard equipment on some types of bag house. On bag houses which operate without any fan controls, there may be additional energy savings from the fan, as its power will be reduced due to a higher average filter differential pressure and reduced air flow. On bag houses with fan controls (VFD, inlet guide vane, dampers) the fan may consume more energy if filter cleaning is reduced. In general, compressed air energy consumption by a baghouse is small in comparison to the baghouse fan energy. The ratio of fan energy use to associated compressed air use may be 100:1 or more. Compressed air measures can affect the more significant fan power consumption, and energy efficiency upgrades should address the broader system in most instances.  Waste Heat Recovery: Most of the electrical energy consumed by an air compressor is rejected as heat. Instead of rejecting this heat to the atmosphere, it can be used to heat air or water and reduce the use of other heat sources. About 85% of the electrical input energy of an air compressor is rejected as heat and vented to the atmosphere. The most common use of this heat is to duct the cooling air from air cooled compressors into a shop or manufacturing space during the winter. During the summer, the damper is set to discharge the air outside. Water can also be heated (or pre-heated) in water cooled compressors. This may require installing special heat exchangers to Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-8 satisfy potable water requirements. The reclaimed heat primarily displaces natural gas consumption in PacifiCorp service territory. 3.2 COMPRESSED AIR MEASURE TECHNOLOGY REVIEW Table 3-2 identifies the key informational resources utilized to conduct the compressed air measure technology review. Table 3-2. Compressed Air Measure Informational Resources Measure CE E DE E R EN E R G Y S T A R RT F In d u s t r i a l Te c h n o l o g i e s P r g m Pa c i f i C o r p 2 0 0 7 Ma r k e t S t u d y Xc e l E n e r g y 2 0 0 6 Ma r k e t S t u d y Compressed Air Measures       CEE/Compressed Air Challenge: The Consortium for Energy Efficiency is a primary sponsor of the Compressed Air Challenge (CAC), a voluntary collaboration of industry representatives, State agencies, utilities and other energy efficiency organizations that aim to improve the performance of existing compressed air systems. The CAC publishes the Best Practices for Compressed Air, an industry reference source used by end-users to optimize installed compressed air systems. In cooperation with the U.S. Department of Energy – Office of Energy Efficiency and Renewable Energy (US DOE-EERE), the Compressed Air Challenge sponsors training workshops throughout the country aimed at boosting the energy efficiency of compressed air systems and training participants to become AirMaster+ Compressed Air Software qualified specialists.  Regional Technical Forum: The Regional Technical Forum (RTF) was the key information resource reviewed for compressed air measures. The Regional Technical Forum is an advisory committee established by the Northwest Power and Conservation Council in 1999 to develop standards related to the evaluation and verification of energy savings from conservation. One of the primary roles of the Council has been to support the energy efficiency services offered by the Bonneville Power Administration. The RTF does not itself operate or fund resource acquisition or market transformation programs. Rather, the RTF prepares and maintains a list of energy efficiency measures and renewable resource options that are eligible to qualify for credit when submitted to Bonneville by its customer-utilities. Measures are evaluated, reviewed, and approved for listing by the RTF. In some cases, where the performance of a measure is sufficiently quantifiable and repeatable, deemed savings for the measure are included in the approval. Following is the list of conservation measures and activities for compressed air which are eligible under Bonneville Power Administration programs: Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-9  Installation of efficiency improvements such as humidity controls for the purge function on twin tower dryers,  Automatic shutdown timers,  Compressor change outs,  Improved sequencing controls,  Adding receiver capacity to systems with load/unload controls,  Piping upgrades,  Reduction of air leaks when accompanied by an ongoing monitoring and maintenance program, and  Adding unloaders to existing or proposed compressed air systems. Deemed savings have not been established for any of these measures. Savings are calculated on a custom basis for each project by BPA technical staff, local utility staff, or technical contractors brought in by either BPA or the local utility to assist with the project. Efficiency incentives are paid by the utility providing electric service to the end-use customer, not by the RTF.  Industrial Technologies Program: The US DOE-EERE distributes and maintains the AirMaster+ Compressed Air software program, which is designed to model the operation of a compressor and evaluate the energy savings and effectiveness of a number of different system upgrades and operational changes. The US DOE-EERE sponsors the Compressed Air Challenge training program and publishes a sourcebook outlining ways to improve compressed air system performance.  PacifiCorp and Xcel DSM Assessments: The PacifiCorp 2007 Systemwide DSM Assessment determined the end-use savings potential of air compressor improvements and air compressor operations and maintenance measures each at 18% of baseline energy consumption. The Xcel Energy 2006 Colorado DSM Market Potential Assessment described groups of compressed air measures consisting of controls, system optimization, sizing, and operations and maintenance, but did not provide savings potential estimates. 3.3 COMPRESSED AIR MEASURE UTILITY PROGRAM REVIEW Except for the Focus on Energy program in Wisconsin and the Energy Trust of Oregon, none of the evaluated utilities currently offer non-residential customers a prescriptive incentive for the evaluated compressed air measures. The Focus on Energy program offers a prescriptive incentive only for a new VSD-equipped compressor while the Energy Trust provides prescriptive incentives for a selection of common compressed air measures through the Production Efficiency program for small industrial customers. Nearly all utilities provide incentives for compressed air measures through custom incentive programs which pay incentives based on the estimated energy savings. Table 3-3 summarizes the utilities who offer a structured custom incentive specifically for qualifying compressed air efficiency measures. Each utility program is reviewed below. Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-10 Table 3-3. Compressed Air Measure Utility Prescriptive DSM Program Review Measure Al l i a n t En e r g y AP S Av i s t a BP A En e r g y T r u s t Id a h o P o w e r Mi d A m e r i c a n E n e r g y Ne v a d a P o w e r PG & E PS E Qu e s t a r Se a t t l e C i t y L i g h t Xc e l E n e r g y Compressed Air Measures      Alliant Energy/Focus on Energy: The Focus on Energy program in Wisconsin offers incentives for customers who perform a compressed air system audit or leak survey. A rebate of up to $7,500 is available to customers to have a system audit performed that logs compressor kW and system pressure for one week, provides a detailed system description and makes improvement recommendations with estimated energy savings and costs. Any customer who performs a qualifying leak survey can receive up to 50% of the survey cost and a matching amount if the leaks are repaired within 90 days. Additionally, the program offers a post-purchase prescriptive incentive of $70/hp for a new CAGI-certified, VSD-equipped compressor that replaces an existing oil-flooded, air-cooled screw compressor of similar size.  Bonneville Power Administration (BPA): BPA provides technical support to industrial end-users in collaboration with its utility customers serving those end-users. Technical support is targeted at identifying industrial energy-efficiency opportunities, prioritizing the most promising opportunities by savings potential as well as likelihood of follow- through on the part of the end-user customer, and supporting implementation with custom engineering studies, savings calculations, data logging, data analysis, and M&V activities. Compressed air efficiency measures are encouraged and supported as an important source of savings in the large industrial sector, and compressed air is a common opportunity identified in the scoping studies. This custom approach, however, is available primarily to larger industrial customers because the costs involved in providing detailed scoping and engineering to smaller operations with limited savings potential is high. There is a lively interest in exploring and developing more streamlined, cost-effective approaches to identify and deliver compressed air savings in smaller facilities, or on small, well-defined projects in larger facilities. Incentives are currently administered in the following manner. The regional utilities who purchase power from BPA determine the specific details of the incentive offerings that they pay to their end-use industrial customers. As a result, incentive rates and caps vary. The maximum rate a utility is able to claim credit for within the agreements they have with BPA (the Conservation Rate Credit or Conservation Augmentation Agreement) is 12 cents/kWh if they have elected to make use of BPA technical services; 15 cents/kWh if not. Some utilities Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-11 elect to provide their own technical services. The basic incentive rate will depend on which utility’s service territory a project takes place within; it may be 9, 12, or 15 cents/kWh. Project cost caps also vary, with 70% of incremental cost as the maximum. Some utilities use 50%. For projects involving compressors less than 100 hp, a convenient Excel-based tool (created by Cascade Energy Engineering) which is available on the BPA website may be used in lieu of an engineering study. This is a recent development that hasn’t been marketed broadly, so substantial vendor uptake has not yet emerged at this time. The Energy Trust of Oregon has recently begun a more intensive outreach with a tool-based approach for smaller industrial compressed air projects. This is an area of great opportunity to build a coordinated, collaborative approach across the Pacific Northwest region.  Energy Trust of Oregon: The Energy Trust of Oregon’s resource acquisition program in the industrial sector is called “Production Efficiency.” Services offered to the larger industrial customers of PGE and Pacific Power include no-cost energy audits, engineering studies, limited project management oversight, commissioning assistance, and incentive funding. The ETO program is administered by three Program Delivery Contractors (PDC’s), who either provide these services themselves or use Allied Technical Assistance Contractors (ATACs) to perform preliminary walkthroughs and detailed engineering studies. Most projects in the Production Efficiency program use the custom track to determine incentives. A prescriptive incentive path is also available for relatively simple projects such as motor replacement, lighting, and certain HVAC measures. In the area of compressed air, both supply and demand-side equipment is eligible for incentive funding, either as a retrofit or as new construction project. Incentives are paid at the rate of 15 cents per kWh saved, with an incentive cap of 50% of project cost. These savings are determined during the course of the study provided by the PDC or the ATAC, which often involve data logging to characterize the load profile on the compressed air system. Besides efficient compressor and control configurations, additional measures are commonly recommended, such as adding appropriate receiver capacity, establishing leak repair programs, and altering the distribution system. There are no prescriptive measures for compressed air at present. The custom-study method used for large industrial projects has not produced as many smaller projects as desired. Cost effectiveness has been an issue, and the paperwork-process burden perceived by vendors and contractors appears to be a barrier. However, ETO recently initiated a series of prescriptive compressed air measures which make of use of Excel-based tools that feature a straightforward set of inputs tailored specifically for use by vendors. This is part of a new emphasis on reaching small customers in the industrial segment. The Small Industrial Initiative has an expanding set of Excel-based tools and prescriptive measures, using elements of the successful lighting trade ally approach among other groups of vendors serving the small industrial market. The vendor-trade allies are the primary delivery mechanism for the program. Program and tool design focus on supporting and educating them and on streamlining the participation process. Transparency, ease of use, and Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-12 quick turnaround are vital if vendors are to become advocates of the program and proactively drive projects to completion. Notably, the Excel tool integrates the technical input with program participation forms and Oregon Business Energy Tax Credit applications. To date, two Excel-based tools have been developed and tested. One is for the replacement of a single compressor with a single compressor, and the second for the replacement of two compressors with a single compressor. The Energy Trust Program Delivery Contractor for small industrial customers meets with each compressed air vendor individually to present the tool, provide guidance on its use, provide training on Energy Trust processes, and to have an exchange about mutual expectations. Vendors who wish to use the tool and actively participate in the program become Energy Trust trade allies, and will be listed on the Energy Trust website as such. The tools are intended for use with compressors up to 75 hp. Data logging to establish the baseline operating profile is encouraged but not required. Application of the tool may be extended to compressors up to 100 hp if data logging is used to characterize system operation in order to improve the confidence of energy savings estimates and operating cost reduction. Once the processes associated with these tools are well established, attention will be turned toward the development of streamlined methods to address other compressed air opportunities on both the supply side and the demand side, including many listed in this document.  Xcel Energy: Xcel Energy provides a structured approach to identifying and implementing measures to improve the efficiency of compressed air systems. Only compressed air systems larger than 50hp can qualify for the program. Xcel Energy provides an incentive to customers to defray the cost of a compressed air system audit performed by a qualifying alliance vendor or engineering consultant. The audit results in a report with a list of system recommendations, rebate opportunities and estimated energy savings. The incentive for obtaining a system audit is 100% of the compressed air audit, up to $2,500 for systems between 50 and 99hp, and 75% of the costs up to $15,000 for systems 100hp or larger. Once the report is completed, customers must obtain pre- approval for any measures they wish to implement. Xcel Energy pays an additional incentive of up to $200 per kW saved following the installation of pre-approved compressed air efficiency measures. 3.4 COMPRESSED AIR MEASURE CODE REVIEW Compressors and components of compressed air systems are not subject to any energy performance requirements in either State or Federal codes. The major compressed air industry organization, the Compressed Air and Gas Institute (CAGI), has developed a voluntary performance certification program for lubricated rotary screw compressors from 50-200hp and standalone refrigerated compressed air dryers from 200-1,000 scfm. CAGI certifies manufacturer’s stated air flow capacities and efficiencies and allows manufacturers to post the CAGI Program Verification Seal on the equipment. CAGI randomly tests two units per participant per year to verify that the submitted ratings accurately represent the equipment listed Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-13 on their website. The certification program is barely established and only included fourteen (14) compressors from 8 manufacturers as of May 2008. 3.5 COMPRESSED AIR MEASURE VENDORS Table 3-4 and Table 3-5 contain contact information for three identified vendors of compressed air systems within Idaho and three baghouse control vendors, respectively. Table 3-4. Idaho Compressed Air Vendors Vendor Phone Number Air Equipment Co. (208) 342-2464 Atlas Copco (509) 928-2353 Maddox Compressor (801) 731-4000 Table 3-5. Bag House Filter Vendors Vendor Phone Number Baxter Air Engineering (425) 486-6666 G.E. Energy (800) 821-2222 EAG/Goyen (805) 527-3878 Vendor feedback by measure included the following:  Engineered Nozzles: Only one compressor equipment vendor stocked or sold compressed air nozzles regularly. These nozzles were limited to sandblasting nozzles and blow gun nozzles that would be used for blowing off equipment or personnel. This vendor offers “standard” and venturi-type nozzles. Standard nozzles are priced at $10 to $30 based on size. Venturi nozzles are two to three times the cost of standard nozzles. About 50% of blow gun nozzle sales were venturi-type nozzles. Most compressor equipment vendors have access to compressed air nozzles if a customer requests them, but sell very few or none.  Low Pressure Drop Filters: No vendors stocked low pressure drop filters. Most vendors reported that these filters comprise 10% or less of total coalescing filter sales, with about half reporting 5% or less. Two vendors indicated 50% of filter sales were low pressure drop type. Deep bed filtration is very rare on small systems, generally under 75 HP. On large multiple compressor systems it becomes more common. Two vendors commented that installation is much higher with utility participation. Most vendors indicated that the low pressure drop filters are three to ten times the cost of standard coalescing filters. Two vendors indicated that the incremental cost was 30-50%.  Pressure/Flow Controllers: No vendors stocked large flow controllers. One vendor stocked smaller simpler regulator type units. Most vendors reported that pressure/flow controllers are sold with 5% or less of new systems. One vendor reported 25% and Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-14 another 50%. Occasionally vendors sell these on a retrofit basis, which is frequently with some utility involvement.  Purge Control On Desiccant Dryers: No vendors stocked desiccant dryers. Purge saving controls are ordered with a new dryer and supplied by the factory. No vendors indicated that they retrofit existing dryers with purge saving controls. Vendors almost unanimously reported that purge saving controls are sold with about 50% of desiccant dryers. The percentage increases with dryer size. The cost to add purge saving controls is fixed, regardless of the dryer size, as the same controls package is used on small and large dryers. Most vendors reported that installing the purge controls added $2,000 to $4,000 to the price of the dryer. One vendor indicated that purge saving controls were standard on dryers over 200 SCFM (about 40 HP). Another vendor indicated that they have three types of controls, including standard timer controls, “better” controls which reduce purge losses somewhat and add 5% to 10% to the price, and “best” controls which maximize purge savings and add 25% to 50% to the cost of the dryer.  Receiver Capacity Addition: All vendors stock smaller receiver tanks, up to about 400 gallons, and can deliver larger tanks within a few days. All vendors reported that new systems are nearly always sold with some receiver tank capacity, and that it is up-sold whenever possible. Most vendors reported some retrofit sales to help solve customer problems or as part of energy upgrades with utility involvement.  Refrigerated cycling dryers: There was no consensus on refrigerated dryer stocking. Some vendors don’t stock refrigerated dryers, some stocked only small non-cycling dryers, others stocked both cycling and non-cycling dryers, but typically in the medium and small sizes. Cycling dryer sales percentages also varied widely, but a common trend seems that cycling dryers comprise 25% or less of sales in the smaller sizes (under about 300 SCFM or about 75 HP), but about 50% or greater of sales in larger sizes. The incremental cost of upgrading to a cycling dryer was generally between 10% and 20%.  VFD Controlled Compressor: Stocking varied among vendors, but most vendors are able to order variable speed compressors on a time schedule similar to fixed speed compressors. Most vendors reported variable speed compressor sales comprised about 25% of total screw compressor sales. Of these sales, vendors indicated that the utility was involved in about 75% of the projects. The cost premium was commonly reported at 25% to 30% to upgrade from a fixed speed to a variable speed compressor.  Zero Loss Condensate Drains: Most vendors stock both zero loss drains and dual timer drains. The majority of vendors reported that zero loss drain sales were 25% or less of drain sales. One vendor reported 50%, one 90%, and one reported that he no longer sold timer drains at all, but only sold zero loss drains. Nearly all vendors reported that zero loss drains were about twice the cost of dual timer drains.  Outside Air Intake: None of the vendors stocked or sold a device that automatically selected the source for the compressor intake air. Only one vendor had heard of automatic controls for this. He reported that years ago a control package was offered by another manufacturer that changed both the inlet air source and waste heat air routing Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-15 automatically, but few systems were sold and the system is no longer available. Another vendor reported that systems that use outside air need to have a damper to allow them to use compressor room air during very cold weather to avoid compressor problems. Vendors reported that outside air is ducted to the inlet on relatively few systems, generally about 5% to 10%. It is more common on larger systems. Some vendors recommend that customers duct outside air to the compressor inlet, but the installation is generally done by the customer or their contractor.  Automatic Bag House Filter Cleaner Controls: Only two compressed air equipment vendors had any sales of bag house controls, and these were low volume. Three bag house or bag house control system vendors were contacted about automatic filter cleaner controls. Two of these three vendors were positive about the benefits of energy savings and increased bag life. One vendor felt they were only appropriate on paper cartridge type filter systems where cartridge life is relatively short, and that controls were not appropriate on bag houses with felted filter bags. This vendor recommends customers disable automatic controls from felted filter bag systems, stating they can decrease bag life by allowing small particles to clog the bags during extended periods when the bags are not being cleaned. These controls can be added to new systems before they are shipped from the factory, or retrofit on existing systems. Equipment cost estimates ranged from $400 to $700. Installation cost probably exceeds the equipment cost in most retrofit situations.  Waste Heat Recovery: All vendors said they discuss waste heat recovery with their customers and recommend it. This invariably referred to using hot air from of air cooled compressors to help heat a building in the winter. None of the vendors were familiar with installations heating water in water cooled compressors. Only one vendor had an “off the shelf” duct/gate product that allows the hot air off of the aftercooler to be ducted into a building or outside. Another vendor selects and sells a gate component for a contractor to install. Most vendors would give the contractor the engineering information, and allow the mechanical contractor to design and install a custom system. Costs vary widely depending on the installation specifics. Vendors contacted also provided feedback about the timing of upgrade purchases, payback estimates, some other common compressed air measures and their suggestions to increase the percentage of efficiency measures installed. Timing of Upgrade Purchases: Vendors reported that efficiency upgrades are more likely to be sold on a planned replacement or new construction basis than in an emergency breakdown situation. Some upgrades are sold in emergency breakdown situations, if the right size equipment is in stock. Vendors indicated that upgrades are far more likely with utility participation due to incentive money and unbiased recommendations. Payback Estimates: Vendor payback estimates varied dramatically within the same measure, and often depended on the size of system. Other Efficiency Upgrades: Other energy upgrades mentioned by vendors include: Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-16  Turn valve, spiral valve, and lift valve compressor control - These are generically called variable displacement controls, and provide for very good part load compressor efficiency between about 67% and 100% capacity.  Sequencers and controllers - Many vendors offer a sequencer that can control multiple air compressors.  Audits - Many vendors will perform compressed air system audits.  Vacuum pump systems - Instead of using compressed air in venturi vacuum generators, install a central vacuum system.  VFD cooling fan - This system adjusts the speed of the compressor cooling fan based on oil temperature. Noise reduction is another benefit.  Air reheating - This system transfers heat from the oil to the compressed air. Hotter air performs more work at the end user.  Heat of compression dryers - These dryers can be used on oil free compressors, and consume very little purge air.  Premium high efficiency motors - Available as an option on fixed speed compressors.  Wye-delta starters - These reduce inrush current and starting motor torque. They are standard on some compressors, optional on others.  Two stage compressors - Two stage oil flooded compressors are slightly more efficient than single stage compressors.  Point of use regulators - These reduce air consumption and artificial demand.  Condensate controls - Some condensate control systems reduce air consumption by timer drains.  Auto start/stop control upgrades to older compressors - This control upgrade allows older compressors to shut off during periods of low demand. Vendor Recommendations: Vendors recommended the following steps to increase the percentage of efficiency measures installed.  Start incentives, continue incentives, higher incentives - All vendors were very much in favor of utility incentives and expressed a desire to see them start, continue, expand, and increase. The relative lack of incentives in California and Idaho PacifiCorp service territories was noted by vendors in those areas.  Fast track incentives for breakdown/emergency situations - An option was desired for customers in breakdown situations to be able to purchase an efficiency upgrade immediately, and then have the incentive calculated after the equipment is installed.  Fixed incentives - A list of fixed incentives was requested, such as $10,000 for a 200 HP variable speed air compressor. The vendor and customer would know the incentive Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-17 ahead of time without the need for analysis, pre-approval signatures, and other steps that delay the purchase of equipment.  Faster processing - The lead time for all of the standard steps in the incentive program can be prohibitive and discourages some vendors from involving the utility in some projects.  Find some way to help small customers - Audits are less common on small systems but energy upgrades are still available.  Vendor education on incentive programs - Some vendors knew little or nothing about existing incentive programs and wanted to learn more.  Customer education on compressed air costs and incentive programs - Promote measures to customers directly through fliers. Educate customers on the cost of compressed air and how measures can increase the availability of compressed air. Publicity directed to maintenance managers is more effective than something included in the electric bill which is only seen by accounts payable.  Sponsor Compressed Air Challenge training in the service territories. 3.6 PRESCRIPTIVE RECOMMENDATIONS A post-purchase prescriptive incentive delivery mechanism with deemed savings values is the preferred method to target customers with small compressed air systems (≤ 75 hp) in order to limit administrative costs and paperwork, maximize participation from compressed air vendors, and increase implementation of energy-saving compressed air upgrades. Of the 11 evaluated compressed air measures, 5 are recommended for post-purchase prescriptive incentives and one for a post-purchase calculated incentive, as shown in Table 3-6. Eligibility for post-purchase prescriptive incentives will be restricted to single compressor systems less than or equal 75 hp. Projects with single compressor systems larger than 75 hp or with multiple compressors should receive a custom engineering analysis through the Energy FinAnswer program. Due to the uncertainty of typical pressurized operating hours across the large variety of compressed air systems, it is recommended that deemed savings calculations should include an input for hours of pressurized operation for each individual project and the value should be requested on the FinAnswer Express incentive application. In cases where a fixed value for deemed savings is preferred, 4,000 pressurized system hours is recommended as the most reasonable input. The use of AIRMaster software or simplified analysis spreadsheets by customers or vendors as part of a post-purchase prescriptive incentive program to simplify the application process and refine deemed savings estimates should be evaluated as part of the design phase of the program. A simplified analysis is recommended for VFD-controlled compressors where a spreadsheet calculation tool is used to estimate the energy savings and calculate the incentive amount based Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-18 on the estimated energy and demand savings. Pre-approval is recommended but not required for the customer to be eligible to receive incentives for installing a VFD controlled compressor. Two measures – engineered nozzles and pressure/flow controllers – are not recommended for prescriptive incentives due to the uncertainty of deemed savings and cost estimates and the difficulty of implementing these measures via a post-purchase incentive delivery mechanism. The remaining three measures – automatic bag house filter cleaner controls, waste heat recovery, and purge controls for desiccant dryers – are not recommended for a prescriptive approach at this time for the following reasons:  A typical baseline for bag house compressed air consumption, particle load, control strategy and fan energy could not be constructed with available data,  Waste heat energy measures save considerable heating energy, primarily provided by natural gas, but little or no electrical energy and present little opportunity for cost- effective electrical energy savings, and  Purge-savings controls for desiccant dryers have a high fixed cost and are only attractive for customers installing the controls on dryers that serve compressed air systems larger than 75 hp. Table 3-6 contains a summary of the recommended measures to include in the prescriptive incentive program. Table 3-6.

The recommended prescriptive incentives would be marketed to customers using a dedicated compressed air trade ally network. Vendors that provide compressed air system service, sell compressed air equipment, or conduct system analysis of existing systems will be recruited to the trade alliance. Trade ally members would be educated about the incentives and eligibility requirements available for each measure and would serve as the primary point of contact to deliver the program to the customer. Trade allies will be responsible for discerning whether compressed air systems qualify for prescriptive incentives and, if not, alerting the customer to custom engineering options offered by Rocky Mountain Power through the Energy FinAnswer Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-19 program. A Rocky Mountain Power Alliance coordinator would serve as the primary point of contact for approved compressed air Alliance members and support members in a fashion similar to the existing HVAC and lighting Alliances. Delivery of the compressed air prescriptive incentive program should be coordinated with the existing Compressed Air Challenge training and program materials as much as possible to encourage the use of compressed air Best Practices, AIRMaster software, and to leverage existing networks of compressed air professionals. Identifying and communicating where prescriptive incentives overlap with established compressed air Best Practices should be a priority to support the trade ally network. 3.7 COMPRESSED AIR MEASURES BASELINE  Low Pressure-drop Filters: The baseline for this measure is “standard” coalescing filter that requires element replacement every 6 to 12 months.  Receiver Capacity Addition: The baseline for this measure is a weighted combination of screw compressors at 15, 25, 50, 100, and 200hp operating with load/unload controls with 2 gallons of tank capacity per trim compressor cfm.  Refrigerated Cycling Dryers: The baseline for this measure is a series of non-cycling refrigerated dryers serving 15, 25, 50, 100, and 200 hp compressors.  VFD Controlled Compressors: The baseline for this measure is a series of typical single fixed speed compressor operations modeled at 15, 25, 50, 100, and 200 hp. A blended part load performance for fixed speed compressor control was used, and estimates were made on the average compressor capacity.  Zero Loss Condensate Drains: The baseline for this measure is a weighted average of three dual timer drains configured with various settings to reflect typical usage and modeled for a series of typical compressor operations for 15, 25, 50, 100, and 200hp.  Outside Air Intake: The baseline for this measure is a weighted combination of single compressors at 15, 25, 50, 100 and 200 hp operating with an average inlet air temperature 25°F higher than compressors fitted with outside air intake. 3.8 COMPRESSED AIR MEASURE MINIMUM ELIGIBILITY REQUIREMENTS Table 3-7 provides details on the recommended minimum eligibility requirements for the compressed air measures evaluated. Any compressed air measure may be implemented by the customer either alone or in combination with any number of other measures. For some measures, the customer is required to purchase a zero loss condensate drain to qualify, in which case the purchased and installed zero loss condensate drain qualifies for a separate incentive. Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-20 Table 3-7.

Table 3-8 contains the estimated savings, incremental customer costs and recommended incentive level for each compressed air measure. Incentives for recommended prescriptive measures are provided assuming 4,000 hours per year of pressurized operation. Interactive effects of implementing multiple compressed air measures is minimal, so deemed savings estimates are additive when a customer elects to install multiple measures. Incentive applications should request additional information from the customer to verify deemed savings estimates based on compressor size, annual operating hours and system operating pressure. In general, the analysis looks at capital costs and energy performance in discrete compressor sizes from 15 hp to 200 hp. Once the analysis was completed for these individual sizes, the overall savings and costs were blended with a weighted averaging technique based upon past observations regarding relative frequency of applications over this size range to estimate deemed savings and costs. These weightings vary by measure and are based upon past experience of Cascade Engineering (i.e. projects that are sufficiently large to warrant attention or small systems Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-21 with a motivated participant or vendor). The savings assumptions are also based upon reasonably wise application of the technologies. As a result, deemed savings and cost estimates will be applicable only to single-compressor systems no larger than 75 hp; larger systems or systems with multiple compressors will require a customer engineering analysis to accurately determine the energy savings and costs associated with energy efficiency measures.

Section 3 Compressed Air 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 3-23 3.10 COMPRESSED AIR MEASURE OUTLOOK There is significant interest among utilities throughout the Pacific Northwest to realize energy savings in compressed air systems in a cost-effective manner. Existing “custom” energy efficiency programs have successfully targeted large customers with complex compressed air systems but have failed to realize energy savings among customers with smaller, simpler compressed air systems. To that end, a study was commissioned by the Energy Trust of Oregon and co-funded by PacifiCorp to examine the market for small compressed air systems and suggest methods for realizing cost-effective energy savings. A prescriptive or semi-prescriptive program with Trade Ally support and streamlined customer participation process is the favored approach to target customers with smaller compressed air systems. Engaging compressed air vendors and Trade Allies in a simple, easy-to-understand program with transparent incentive amounts and eligibility requirements is critical to enable them to identify and implement compressed air energy efficiency measures in smaller compressed air systems. The Energy Trust of Oregon is the only program currently offering prescriptive incentives for compressed air measures, so coordination among Pacific Northwest utilities and trade alliance participants will be important to implement a prescriptive compressed air incentive program successfully. 2008 FinAnswer® Express Market Characterization – Idaho 4-1 Section 4 Envelope 4.1 ENVELOPE CATEGORY OVERVIEW The building envelope includes the interface between the building and the exterior environment. Envelope measures involve making improvements to the thermal resistance of the walls, roof, and windows of the building. Additional insulation on the exterior walls and roof of a building will reduce the heating and cooling loads. One potential new measure was investigated, in addition to four existing envelope measures offered in Idaho. Table 4-1 summarizes the specific measures evaluated in this section. Table 4-1. Evaluated Envelope Measures Existing FinAnswer Express Envelope Measures Potential New FinAnswer Express Envelope Measures Cool Roofs Reflective Window Film Attic/Roof Insulation High-Efficiency Windows Wall Insulation 4.1.1 Envelope Measure Descriptions Detailed descriptions of the individual envelope measures identified in Table 4-1 include:  Cool Roofs: This measure includes a variety of paints, coatings, tiles and other materials applied to or incorporated into roof materials that reduce the amount of solar radiation absorbed by a facility’s roof. Cool roofing materials have high solar reflectance and high radiative emittance that reduce solar gain of the roof and subsequently reduce the cooling load for the space during warmer months. However, cool roofing material can increase heating loads during cooler months.  Attic Insulation: Attic insulation reduces the rate of heat loss through the ceiling/roof assembly of a building. Insulation is rated according to an R-value, with higher values providing a higher resistance to heat loss.  High Efficiency Windows: High-efficiency windows are designed to reduce the rate of heat transfer through the window assembly and prevent solar heat gain while still allowing sufficient light through the window to illuminate the space. The National Fenestration Rating Council (NFRC) certifies the energy performance of windows in two categories, thermal transmission which is measured by a U-factor and solar heat gain which is measured by the Solar Heat Gain Coefficient (SHGC).  Reflective Window Film: Window films are thin layers of polyester film that are typically applied to existing windows to reduce solar heat gain. A “spectrally selective” window film reduces the solar heat gain while minimizing reductions in the amount of visible light transmitted to the interior of the building. The National Fenestration Rating Council certifies the SHGC and visible transmittance of window film products from participating manufacturers. Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-2  Wall Insulation: Wall insulation reduces the rate of heat loss through the walls of a building. Insulation is rated according to an R-value, with higher values providing a higher resistance to heat loss. 4.2 ENVELOPE MEASURE TECHNOLOGY REVIEW Table 4-2 identifies the key informational resources utilized to conduct the envelope measure technology review.

Baseline data was included with many resources. Detailed measure cost and savings data obtained from the sources identified in Table 4-2 are provided in Appendix B. Key information for each measure is summarized below.  Cool Roofs: Cool Roofs were evaluated as part of both the PacifiCorp 2007 Systemwide DSM Assessment and the Xcel Energy 2006 Colorado DSM Market Potential Assessment. ENERGY STAR recently updated the cool roof products specification to version 2.0 on December 31, 2007. The DEER database provides gross customer costs for cool roofs. The Department of Energy (DOE) developed an on-line calculator to quantify the energy savings associated with installing a cool roof.  Attic and Wall Insulation: Nearly every resource reviewed touched on attic insulation, but few focused on wall insulation in commercial buildings. The DEER database provided gross customer cost information for both attic and wall insulation. RTF provided incremental costs and energy and demand savings estimates for small commercial spaces.  High-Efficiency Windows: ENERGY STAR has developed a specification for high-efficiency windows based on climate zones for residential applications that install NFRC rated windows with specific U-factor and SHGC values. Incremental costs and measure life information is provided by both DEER and RTF for commercial buildings. Energy Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-3 savings potential was evaluated as part of both the PacifiCorp and Xcel Energy DSM studies.  Reflective Window Film: Reflective window films were evaluated as part of the Xcel Energy 2006 Colorado DSM Market Potential Assessment which provided cost, measure life, and % energy savings compared to a baseline. The DOE Industrial Technologies Program provides limited information on envelope measures. However, it has developed a number of useful resources and sponsors multiple initiatives and industry collaborations to improve the envelope performance of commercial buildings. Among these incentives are the High-Performance Buildings Initiative and the Zero Energy Building Initiative. CEE performed an evaluation of utility programs nationwide, identifying which programs offered incentives for envelope measures in 2005. 4.3 UTILITY ENVELOPE DSM PROGRAM REVIEW Table 4-3 identifies which of the evaluated utilities currently offer non-residential customers a prescriptive incentive for the reviewed envelope measures.

Qualifying installations receive an incentive of $0.05 per square foot.  Attic/Wall Insulation: The most common prescriptive incentives are offered for attic and wall insulation. In all cases, insulation incentives are limited to those spaces conditioned with mechanical heating/cooling equipment and are generally limited to retrofit applications only. Incentives are generally provided for upgrading existing Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-4 insulation to a predefined R-value. Idaho Power and PGE specify the type/amount of existing insulation that must be replaced to qualify for an incentive. Incentive amounts range from $0.05 to $0.45 per square foot of installed insulation.  High-Efficiency Windows: Questar and Idaho Power offer incentives for windows that have U-factors ≤0.42. Idaho Power also specifies a maximum SHGC of 0.40 and offers additional incentives for windows that have visible light transmittance of 0.50 or greater. Incentive amounts range from $0.50 to $1.00 per square foot. Alliant Energy offers incentives for any ENERGY STAR qualified window at $25 per window. All programs required that windows be NFRC rated.  Reflective Window Film: Three utilities offered incentives for reflective window films. Incentives were only offered for films installed on non-North facing windows. A maximum SHGC is specified based on the type of window (single or double-pane). Idaho Power requires that the window films be professionally installed, while Nevada Power and PG&E require that the films carry a 5-year manufacturer warranty. Incentives range from $0.50 to $1.35 per square foot of window film installed. A detailed summary of the utility incentives and qualification requirements is presented in Appendix C. 4.4 ENVELOPE MEASURE CODE REVIEW IECC 2006 defines minimum R-value requirements for walls and roofs for new construction projects, additions to existing buildings, and major renovations based on climate zone. IECC 2006 includes requirements for window U-factor and SHGC based on the projection factor (PF) of the window. Minimum insulation and window code requirements are show in Table 4-4. Roof reflectivity and window films are not regulated by IECC 2006 in Idaho. Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-5 Table 4-4.

Table 4-5. Representative Idaho Insulation and Window Vendors Vendor Phone Number LC Insulation & Supply (208) 357-3939 Harrington and Company (208) 552-6622 Johnson Brothers (208) 525-8600 As part of this evaluation, Nexant surveyed these vendors and others to gauge current market awareness and trends associated with potential prescriptive measures. Some key feedback received included the following:  Most vendors recommend elevated levels of insulation and high-efficiency windows to customers but noted that customers generally are cost-driven and elect to install additional insulation and high-efficiency windows only if the budget is available.  Costs for insulation vary widely depending on the type of building and the type of insulation. Hanging batts of insulation from the ceiling or walls in metal buildings is Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-6 considered the most labor intensive and expensive, while blown-in insulation in attic or wall spaces is the cheapest form of insulation.  Most commercial insulation retrofit projects add insulation to remodeled spaces to comply with energy codes. In many cases, warehouses or other unconditioned spaces are turned into office space and newly constructed walls dividing the office space from the rest of the warehouse must be insulated as exterior walls. Exterior insulation is rarely added, except when changing space types or remodeling a building exterior.  One insulation contractor noted that they have little input on the type/amount of insulation to install in new construction projects because the amount of insulation/type of glazing is specified by the building designer.  Window films are available with a wide variety of performance characteristics and costs. Window film to reduce solar glare/transmission through windows in office buildings is the most common type of application. Window films were only carried by a few of the vendors surveyed.  One vendor noted that application of window films will void the warranty on the window and that glass can be customized to match nearly any of the properties gained by applying window films. Standard window warranties are approximately 10 years.  Most vendors surveyed indicated that the bulk of commercial customers elect to install some sort of low-e glazing product. However, most customers choose the least expensive low-e glazing product available to meet energy codes and not the high-performance low-e glazing.  One vendor in Idaho noted that breather tubes required because of the cold climate degrade the thermal performance of a window, making it difficult to achieve high efficiencies with the same glazing/frame products as can be achieved in other states. The vendor survey instrument and additional vendor responses is provided in Appendix A. 4.6 ENVELOPE MEASURE PRESCRIPTIVE RECOMMENDATIONS No changes are recommended to the existing Cool Roof measure included in the FinAnswer Express program. Changes are recommended to the eligibility requirements and incentives for Attic/Wall Insulation and Windows measures to make them consistent across PacifiCorp territories. Rather than using a deemed savings value like the other four measures, a simplified analysis to calculate energy savings is recommended for reflective window films for the following reasons:  Window films come in many varieties and the energy performance characteristics vary significantly based on the product selected by the customer Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-7  The performance of the existing window must be factored into the energy savings estimates  Energy savings vary based on the orientation of the window. With the exception of reflective window films, all of the recommended measures qualify for incentives if installed in either new construction or retrofit projects. Reflective window films are a post-construction modification and will not be incentivized for new construction projects. Table 4-6 contains a summary of the envelope measure prescriptive recommendations. Table 4-6.

The baseline for calculating the energy and demand savings associated with reflective window films will be the existing window. 4.8 MINIMUM ENVELOPE MEASURE ELIGIBILITY REQUIREMENTS Recommended minimum efficiency requirements for roof and attic insulation, wall insulation and glazing measures for new construction projects are summarized in Table 4-7. For new construction projects to qualify for incentives, an additional increment of R-5 attic/roof insulation or R-3.7ci wall insulation above the amount required by the energy code must be added to the building. To qualify for envelope incentives in existing buildings, the customer must add an increment of R-10 equivalent insulation to the roof or wall assembly. Eligibility for high-efficiency window incentives varies depending on whether NFRC rated window assemblies or site-built windows are installed. Incentives are available for qualifying windows installed as part of either retrofit or new construction projects.

U = U-factor or U-value which is the rate of heat loss through the window assembly including the frame and glass. SHGC = Solar Heat Gain Coefficient, which is the rate of heat gain through the window assembly including the frame and glass Eligibility requirements for high-efficiency windows were targeted to be consistent across all PacifiCorp service territories. Cool roof material shall be labeled under the current ENERGY STAR Reflective Roof Products specification. Reflective window films must be professionally installed and the customer/contractor will be required to submit the square footage of film installed, performance characteristics of the existing window, applied window film specifications, and the orientation of the window (i.e. North, East, South or West). Window films will be eligible for incentives if installed on North-facing windows because a spreadsheet tool will be used to calculate energy savings based on window orientation. For all envelope measures, incentives shall only be available for spaces conditioned by mechanical cooling. 4.9 ENVELOPE MEASURE UNIT COSTS, SAVINGS, AND RECOMMENDED INCENTIVES The savings, costs and incentive levels for Cool Roofs is unchanged from the existing FinAnswer Express program. Estimated measure lifetimes and unit costs were obtained from the Xcel Energy 2006 Colorado DSM Market Potential Assessment for reflective window films. All other measure lifetimes were taken from the DEER Database. Total energy and demand savings for attic/wall insulation and high-efficiency windows were calculated using a building energy simulation model and pro-rated based on the portion of savings attributed to electric energy sources. Savings for retrofit measures assume an additional increment of R-10 of attic or wall insulation is added to an existing building. For new construction measures, savings estimates assume an additional increment of R-5 attic/roof insulation or R-3.7ci wall insulation above the amount required by the energy code is added to the building. Savings estimates for high efficiency windows for both retrofit and new construction assumed windows are upgraded to the Section 4 Envelope 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 4-9 U-factor and SHGC requirements outlined in Table 4-7 for window assemblies and site-built windows. Costs and savings for reflective window film projects will be project-dependent and incentives will be paid based on the amount of savings estimated by a spreadsheet tool. Costs for insulation and window measures are incremental material costs. Table 4-8.

In areas where heating is predominately provided by natural gas, insulation and window upgrades will reduce gas consumption. Coordination with existing and developing commercial weatherization programs offered by gas utilities is important to insure that offered incentive levels are proportional to electric and gas energy savings, project economics are reasonable after consideration of all incentives, eligibility requirements are uniform across programs, and vendor and trade network coordination and participation is consistent between utilities. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-1 5-1 Section 5 Farm Equipment Measures 5.1 FARM EQUIPMENT CATEGORY OVERVIEW Agricultural energy usage makes up a significant portion of the energy consumption in the United States. Energy costs represent an estimated 14% of farm expenditures (Energy Situation for Agriculture, 2005). While the agricultural sector reduced its energy use per square foot through the ‘80s and ‘90s, the agricultural sector remains sensitive to energy costs and recent increases in energy prices have greatly affected farmers (On-Farm Energy Use Characterizations, 2005). The agricultural sector continues to explore opportunities to reduce farmers’ exposure to energy price fluctuations and is receptive to measures aimed at improving energy efficiency. While some of the evaluated measures have been available for many years, the measures are receiving increased attention as methods to improve energy efficiency in the agricultural sector and are becoming more widely adopted by farmers. Some measures in this section are specific to dairy farms, while others have applicability to various farm types. Please note that irrigation related measures are evaluated in Section 8 of this report. As this is a new category of measures for the FinAnswer Express program, no existing measures were reviewed as part of this effort. The specific measures evaluated in this section are displayed in Table 5-1. Table 5-1. Evaluated Farm Equipment Measures Existing FinAnswer Express Farm Equipment Measure Potential New FinAnswer Express Farm Equipment Measures None Automatic Milker Takeoffs Block Heater Timers Circulating Fans Heat Reclaimers (electric water heating) High-efficiency Livestock Waterers High-efficiency Ventilation Systems Milk Precoolers Programmable Ventilation Controller VFDs for Dairy Vacuum Pumps 5.1.1 Farm Equipment Measure Descriptions Detailed descriptions of the individual farm measures identified in Table 5-1 include:  Automatic Milker Takeoffs: Automatic milker takeoffs are devices used with automatic milking machines. They are a type of control designed to remove the milking ‘claw’ when milk flow drops to a preset level. This reduces over-milking and cuts down on the use of the vacuum pump, reducing energy consumption. Some controls come with the added benefit of allowing farmers to track the productivity and milking data associated with each cow. Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-2  Block Heater Timers: A block heater is a device that heats the engine block of tractors and other diesel equipment. The heater is necessary to allow equipment to start in cold weather. Although the heater only needs one or two hours to sufficiently warm the engine block, farmers often leave them plugged in overnight. A block heater timer prevents the heater from running longer than necessary.  Circulating Fans: Circulating fans are used to move air around farm buildings to ensure air quality and livestock cooling. Circulating fan incentives are offered for fan/motor combinations that meet cfm/W ratings according to fan size. Fans are tested by independent bodies such as the Bioenvironmental and Structural Systems laboratory at the University of Illinois or the Air Movement and Control Association International Inc (AMCA).  Heat Reclaimers (electric water heating): Dairy farms need to use hot water for cleaning milk pipes and sanitizing areas. A heat reclaimer takes heat from the warm milk and uses it to warm water used for cleaning or other applications. The heat reclaimer reduces the load on the primary water heater.  High Efficiency Livestock Waterers: Livestock waterers are troughs that get filled automatically and are maintained at a constant temperature. Troughs need to be heated to prevent water from freezing in the winter. High efficiency waterers have thick insulation to prevent heat losses and adjustable thermostats. They may employ a floating insulating cap to prevent heat loss from the surface of the water. The reduced heat loss lowers the power draw from the heating element.  High Efficiency Ventilation Systems: Ventilation systems are used to bring fresh air into a facility and exhaust dirty air, as well as maintain a comfortable temperature for livestock. Incentives are offered for ventilation fan and motor combinations that meet a given cfm/W rating according to fan size. Ventilation fans are rated by the same independent testing bodies as circulating fans.  Milk Precoolers: Milk coming from an automatic milker must be cooled to help preserve it and prepare it for processing and shipment. Generally, it is cooled in a bulk tank connected to a full refrigeration system. A milk precooler is a heat exchanger that uses well water to begin cooling the milk before it enters the bulk tank. This precooling lowers the load on the refrigeration system compressor. The additional energy cost required for pumping the well water is offset by the reduction in compressor energy consumption. The most common type of precooler is a plate heat exchanger. A plate heat exchanger has many metal plates pressed together. The plates have grooves in them through which the milk and cooling water flow. Increasing the number of plates allows increased cooling capacity.  Programmable Ventilation Controller: Ventilation systems are used to bring fresh air into a facility and exhaust dirty air as well as maintain a comfortable temperature for livestock. Programmable ventilation controllers vary the speed of ventilation fans to meet the immediate needs of the facility. This ensures that power is not wasted by Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-3 continuously running the fans when the ventilation requirements of the facility are satisfied.  VFDs for Dairy Vacuum Pumps: Dairy vacuum pumps are required to maintain a constant vacuum supply for proper operation of automatic milkers. Generally, the pumps are designed to provide a vacuum for the largest possible draw. During partial operation, air is bled into the system and the pump still operates at full power. A variable frequency drive (VFD) installed on a vacuum pump can measure the actual vacuum load of the system and reduce the power to the pump. This reduction from full load to partial load can help reduce energy consumption. 5.2 FARM EQUIPMENT TECHNOLOGY REVIEW Table 5-2 identifies the key informational resources utilized to conduct the farm equipment technology review.

The DEER database provided cost, savings, and measure life data for the measures shown in Table 5-2. RTF provided a spreadsheet energy calculator for milk precoolers, as well as case study information from dairy farms with VFDs on vacuum pumps. Although the PacifiCorp 2007 Market Study did not provide information on any farm measures, Quantec, LLC was able to provide unit costs, estimated percent savings, and measure life on all measures except circulating fans, high-efficiency livestock waterers, and programmable ventilation controls. Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-4 5.3 UTILITY FARM EQUIPMENT DSM PROGRAM REVIEW Table 5-3 identifies which of the evaluated utilities currently offer customers a prescriptive incentive for the evaluated farm measures.

For each evaluated measure, Alliant provides a prescriptive incentive for both new construction and retrofit projects. Incentives are offered to customers in Iowa and Minnesota through Alliant’s farm rebate program or to customers in Wisconsin through Focus on Energy (FOE). FOE is a public/private partnership that helps provide energy efficiency incentives for a number of business types. FOE provides incentives for high-efficiency ventilation systems, milk precoolers, and VFDs for dairy vacuum pumps. In addition to providing incentive and eligibility information for each measure, Alliant also has internet based energy calculators for the following measures:  Automatic milker takeoffs  Block heater timers  Heat reclaimers  High-efficiency ventilation systems  Milk precoolers  VFDs for dairy vacuum pumps The incentives for measures associated with dairy farms are offered based on the number of cows being milked because this serves as an indicator of the frequency and volume of use. Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-5 BPA provides a framework and funding for utilities to provide their customers with incentives for the farm measures through their Conservation Rate Credit and Conservation Acquisition Agreement programs. Additionally, BPA offers spreadsheet-based energy savings calculators for vacuum pump VFDs and milk precoolers. A search of the Database of State Incentives for Renewables and Efficiency (www.dsireusa.com) revealed no additional utilities offering incentives for the measures evaluated. 5.4 FARM EQUIPMENT MEASURE CODE REVIEW Federal and State energy codes were reviewed for their applicability to the evaluated measures. None of the measures are subject to any State or Federal energy codes. 5.5 FARM EQUIPMENT MEASURE VENDORS Table 5-4. Representative Idaho Farm Equipment Vendors Vendor Phone Number Keith’s Dairy Service and Supply (208) 436-0410 Alliance Dairy Service and Supply (208) 459-0680 Magiix (208) 777-1530 As part of this evaluation, Nexant surveyed vendors across PacifiCorp’s service territories to identify current market awareness and trends associated with these measures. The vendors surveyed included farm equipment distributors and repair companies providing retrofit and installation services. As many of the measures reviewed pertain to dairy farms, some vendors specialized in dairy farm equipment. However, as all of the measures can be used on dairy farms, it was found that most vendors were familiar with all of the measures. Some key feedback includes:  A number of vendors remarked that the majority of equipment installation is for retrofit and remodeling. Only a small number of new construction projects are seen, and during an emergency repair the customer is more concerned about bringing equipment back online than about energy efficiency.  Many vendors agreed that the majority of their customers installed energy efficient measures. One dealer claimed that 100% of his customers used some form of efficient technology. Installation of VFDs on various pump applications was mentioned by a number of vendors.  One dealer mentioned that one technology he has seen increasing in popularity is centralized equipment controls. A centralized panel enables the farmer to monitor aspects of farm equipment including milk cooling, lighting, ventilation, and pumps.  General consensus is that measure payback is less than 2 years. The vendor survey instrument and additional vendor responses are provided in Appendix A. Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-6 5.6 FARM EQUIPMENT MEASURE PRESCRIPTIVE RECOMMENDATIONS All of the nine evaluated farm measures are recommended for post-purchase prescriptive incentive delivery under the FinAnswer Express Program. Eight of the recommended measures should use deemed savings and costs. Reporting actual costs and using the simplified analysis approach described in Section 5.9 to calculate savings for milk precoolers is preferred in order to account for site specific variations in milk precooler savings and costs. Since high-efficiency livestock waterers are cost-effective only in regions that average more than 6,000 heating degree days each year, Idaho is the only state where this measure is recommended. This is consistent with BPA’s incentive policy for high-efficiency livestock waterers. For the majority of the evaluated measures, the recommended eligibility requirements, estimated savings, and incentives were matched for consistency with Alliant Energy’s Farm Equipment program and BPA. Table 5-5 contains a summary of the farm equipment measure prescriptive recommendations. Table 5-5. Recommended Measures Measure Pre-Purchase Agreement Required Reported Costs Reported Savings Actual Deemed based on project Deemed based on measure Simplified Analysis Deemed based on project Deemed based on measure Automatic Milker Takeoffs   Block Heater Timers   Circulating Fans   Heat Reclaimers   High-efficiency Livestock Waterers   High-efficiency Ventilation Systems   Milk Precoolers   Programmable Ventilation Controller   VFDs for Dairy Vacuum Pumps   Additional information on recommended baselines, measure eligibility requirements, cost, savings, and incentives are provided in the balance of this section. 5.7 FARM EQUIPMENT MEASURE BASELINES The baseline for the majority of measures is a farm without the efficient equipment installed. The baseline efficiency for circulating fans and high efficiency ventilation systems is estimated at 2 cfm/W below the recommended minimum qualifying efficiency for fan motor combinations to receive an incentive. This is established with averages taken from testing at the Bioenvironmental Structural Systems Laboratory at the University of Illinois. Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-7 5.8 MINIMUM FARM EQUIPMENT MEASURE ELIGIBILITY REQUIREMENTS Recommended eligibility requirements for farm equipment measures are summarized in Table 5-6. The minimum eligibility for ventilation and circulation fans is consistent with the requirements of Alliant Energy. Table 5-6.

High-efficiency Ventilation Systems1 12-23” Diameter 11 cfm/W 24-35” Diameter 13 cfm/W 36-47” Diameter 17 cfm/W ≥48” Diameter 19.5 cfm/W Milk Precoolers -- The equipment must cool milk with well-water before it reaches the bulk cooling tank. Programmable Ventilation Controller -- The equipment must control ventilation fans based on temperature or environmental settings. VFDs for Dairy Vacuum Pumps -- The equipment must vary the motor speed in accordance with the air flow needs of the vacuum system. Incentive available for retrofit only. 1 Fans must be tested by an independent rating body such as the Bioenvironmental and Structural Systems laboratory at the University of Illinois or the Air Movement and Control Association International Inc. 5.9 FARM EQUIPMENT MEASURE UNIT COSTS, SAVINGS, AND RECOMMENDED INCENTIVES The customer cost for automatic milker takeoffs, block heater timers, heat reclaimers, and high efficiency ventilation systems is based on Quantec LLC market studies. The customer cost for high-efficiency livestock waterers and VFDs on dairy vacuum pumps is taken from the DEER database. The cost of programmable ventilation controllers is an average cost of qualifying units identified through an internet search. The energy savings for automatic milker takeoffs, block heater timers, heat reclaimers, high efficiency ventilation systems, and programmable ventilation controllers were derived from energy savings calculators provided by Alliant Energy. The savings associated with VFDs on Dairy vacuum pumps is taken from the DEER database. Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-8 Alliant offers incentives based on the number of cows being milked for automatic milker takeoffs, heat reclaimers, milk precoolers, and VFDs on dairy vacuum pumps. For the purpose of consistency across the incentive program and practicality, the incentives recommended for these measures use a unit more appropriate to the measure. The data for heat reclaimers is scaled according to the heat reclaimer size. This is based on information from DeLaval, a prominent manufacturer of dairy farm equipment. The recommended incentive for automatic milker takeoffs is based on the average of 50% of the customer cost and an amount calculated based on first-year savings valued at $0.15/kWh + $50/kW. The incentive for block heater timers, circulating fans, and high efficiency ventilation systems is broadly consistent with the incentive offered by Alliant. The incentive for heat reclaimers is equivalent to 50% of the customer cost. The recommended incentive for VFDs on dairy vacuum pumps is based on averages from BPA, FOE, and the calculated energy cost savings. The proposed incentive for circulating and ventilation fans is consistent with the incentive offered by Alliant. The incentive level represents only a small percentage of the estimated gross customer cost. Market research and farm equipment vendors noted that farmers will replace fans upon failure and rarely replace a fan that is operating properly. Therefore, although the incentive level is low in relation to the total customer cost of a high-efficiency fan, it is reasonable when compared against the incremental cost difference between a standard-efficiency and high-efficiency fan. Table 5-7 summarizes the key measure information evaluated. Table 5-7.

The recommended simplified analysis for estimating the gross annual energy savings for a milk pre-cooler submitted to the FinAnswer Express program is shown in Equation 5-1. CCOP STMyrkWh ××∆×=/ Equation 5-1 where M = the annual milk production of the farm, or yearly weight of milk cooled by the tank downstream of the pre-cooler (lbs/yr) ΔT = the temperature drop of the milk due to the pre-cooler (°F). This value is deemed based on regional well water temperature and the temperature of un-cooled milk. Temperature drop data by state is shown in Table 5-8. S = the specific heat of milk (0.93 Btu/lb·°F) COP = the coefficient of performance of the cooling tank compressor. If this value is known, it may be used in Equation 5-1. Otherwise a conservative average of 2.5 can be used. C = constant (3,413 Btu/kWh) Table 5-8. Deemed Temperature Drop by State State Temperature Drop California 32°F Idaho 47°F Utah 43°F Washington 43°F It is estimated that milk production is fairly consistent during the year and variation throughout the day is minimal. Therefore, the demand savings from milk-precoolers can be found by dividing the energy savings per year by the annual operating hours. 5.10 FARM EQUIPMENT MEASURE OUTLOOK There are no upcoming or proposed changes to farm equipment energy codes on the federal or state level that would require a reevaluation of measure data. However, the high prevalence of milk precoolers and VFDs on vacuum pumps mentioned by farm equipment vendors indicates that these measures may become standard practice in the future and measure eligibility may need to be revisited. As equipment manufacturers upgrade the efficiency of their products, it may be Section 5 Farm Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 5-10 necessary to reevaluate the baseline, eligibility requirements, savings, and incentives associated with each measure. This will be of particular concern for ventilation and circulation fans as the deemed savings potential is based on efficiency improvements rather than installation of equipment. Centralized farm controls are a popular energy efficiency measure employed by a number of farmers and may be a practical measure to examine for inclusion in a prescriptive incentive program at a later date. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 6-1 Section 6 Food Service 6.1 FOOD SERVICE CATEGORY OVERVIEW The food service industry can greatly reduce electric power consumption by upgrading to higher efficiency equipment.

Heat is delivered to the cooking fluid by means of an immersed electric element or band-wrapped vessel.”  Commercial Dishwasher: From ENERGY STAR’s Program Requirements for Commercial Dishwashers Partner Commitments document, “Dishwashing machine means a machine designed to clean and sanitize plates, glasses, cups, bowls, utensils, and trays by applying sprays of detergent solution (with or without blasting media granules) and a sanitizing final rinse.” Types of commercial dishwashers: A. “Under Counter Dishwasher means a machine with an overall height 38 inches or less, in which a rack of dishes remains stationary within the machine while being subjected to sequential wash and rinse sprays, and is designed to be installed under food preparation workspaces. Under counter dishwashers can be either chemical or hot water sanitizing, with an internal booster heater for the latter. For purposes of this specification, only those machines designed for wash cycles of 10 minutes or less can qualify for ENERGY STAR. B. Stationary Rack, Single Tank, Door Type Dishwasher means a machine in which a rack of dishes remains stationary within the machine while subjected to sequential wash and rinse sprays. This definition also applies to machines in which the rack revolves on an axis during the wash and rinse cycles. Subcategories of stationary door type machines include: single and multiple wash tank, double rack, pot, pan and utensil washers, chemical dump type and hooded wash compartment (“hood type”). Stationary rack, single tank, door type models are covered by this specification and can be either chemical or hot water sanitizing, with an internal or external booster heater for the latter. C. Single Tank Conveyor Dishwasher means a warewashing machine that employs a conveyor or similar mechanism to carry dishes through a series of wash and rinse sprays within the machine. Specifically, a single tank conveyor machine has a tank for wash water followed by a final sanitizing rinse and does not have a pumped rinse Section 6 Food Service 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 6-4 tank. This type of machine may include a pre-washing section before the washing section. Single tank conveyor dishwashers can be either chemical or hot water sanitizing, with an internal or external booster heater for the latter. D.

Models may include countertop models, wall-mounted models and floor-models mounted on a stand, pedestal or cabinet-style base.”  Convection oven: From the Food Service Technology Center, “an oven having a motorized fan or blower that circulates hot air uniformly and continuously throughout the oven cavity”. Convection ovens result in faster, more even cooking processes relative to standard or natural convection ovens. Convection ovens are sold with either electric or gas heating systems.  Electric Griddle: From the Food Service Technology Center, “a metal plate heated from underneath by gas burners or electric elements.” Griddles generally include a thermostat for controlling the amount of heat delivered to the metal plate and may vary in size, power input, and griddle plate construction depending on the food product.  Combination Oven: An appliance which cooks food by drawing in heated air through a fan which forces it into the oven cavity, while moisture is created by a steam generator. It is called a “combination oven” because it performs the functions of both a regular oven and a steam cooker, either separately or simultaneously.

The Industrial Technologies Program mirrors ENERGY STAR specifications. ENERGY STAR currently has specifications for residential refrigerators and freezers, residential dishwashers, commercial dishwashers, ice machines, commercial solid-door refrigerators and freezers, electric steam cookers, hot food holding cabinets and electric fryers. As of December 2008, ENERGY STAR is nearing completion of a revision to existing specifications for commercial solid-door refrigerators and freezers. On November 20, 2007 and October 13, 2008, ENERGY STAR announced its intention to develop new product specifications for griddles and commercial ovens respectively. A timeline for completion of these specifications is not currently available. CEE maintains specifications for many of the same categories of high-efficiency equipment listed by ENERGY STAR, including: commercial dishwashers, commercial solid-door refrigerators and freezers, glass-door refrigerators, hot food holding cabinets, ice machines, and steamers. Generally, CEE specifications are aimed at encouraging adoption of the highest efficiency appliances and include specifications for high-efficiency equipment tiers beyond Section 6 Food Service 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 6-6 ENERGY STAR requirements. In some cases (i.e. Ice Machines), CEE specifications are more established and more widely used than new ENERGY STAR specifications. 6.3 UTILITY FOOD SERVICE DSM PROGRAM REVIEW Table 6-3 identifies which of the evaluated utilities currently offer non-residential customers a prescriptive incentive for the evaluated food service measures.

Of the utilities surveyed, few offered incentives for commercial dishwashers, electric griddles, and combination ovens. This may be due to the lack of any longstanding ENERGY STAR or CEE specifications and general confusion in the marketplace about which appliances should qualify as high-efficiency. The incentive amounts and the eligibility requirements of surveyed utility programs are presented in Appendix C. 6.4 FOOD SERVICE MEASURE CODE REVIEW Each of the evaluated food service measures is subject to federal minimum efficiency requirements. These standards are summarized in Table 6-4. Section 6 Food Service 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 6-7 Table 6-4.

Compact refrigerator products are not separate product categories under the standards effective January 1, 1993. Individual states can implement efficiency regulations for any appliances not regulated by the federal government. Currently in Idaho, there are no efficiency regulations for the food service equipment evaluated. The federal government is issuing efficiency regulations for both commercial refrigerators/freezers and ice-making machines on January 1, 2010 that will preempt any state efficiency standards. The Energy Security and Independence Act of 2007 increases efficiency requirements for residential dishwashers. Any standard dishwasher manufactured on or after January 1, 2010 shall not exceed 325 kWh/yr and 6.5 gallons of water per cycle and any compact dishwasher shall not exceed 260 kWh/yr and 4.5 gallons of water per cycle. This act mandates that the Secretary of Energy shall decide on re-examining efficiency regulations for refrigerators/freezers for any units manufactured after January 1, 2014 by December 31, 2010. 6.5 FOOD SERVICE MEASURE VENDORS Table 6-6 contains contact information for three identified vendors of food service measures within PacifiCorp’s Idaho service territory. Table 6-6. Representative Idaho Food Service Vendors Vendor Phone Number Bargreen Ellingson (208) 344-3574 Standard Restaurant Equipment (801) 263-3339 Rush’s Kitchen Supply Co. (208) 523-4818 As part of this evaluation, Nexant surveyed these vendors and others across PacifiCorp’s service territories to identify current market awareness and trends associated with these measures. Some key feedback received included: Section 6 Food Service 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 6-11  Most private customers consider energy efficiency of food service equipment a “second- tier” concern and are more interested in the features, performance, and initial price of the unit. However, government projects and large national grocery chains express more preference for energy-efficient food service equipment.  Food service equipment is purchased during new construction and upon unit failure. Rarely is equipment upgraded before the end of its useful life.  Depending on the region, certain types of food-service equipment will be predominately natural-gas powered (i.e. commercial fryers) while others will be predominately electric powered (i.e. holding cabinets). Multiple vendors noted that it would be pointless to have incentives for electrically-powered equipment if most units are gas powered.  One vendor expressed discontent with the ENERGY STAR label because it does not require independent, third-party certification of the manufacturer’s submitted energy efficiency ratings.  There was high awareness of ENERGY STAR qualifying equipment among the surveyed vendors, but all responded that interest from customers in high-efficiency food service equipment was generally low. The vendor survey instrument and additional vendor responses are provided in Appendix A. 6.6 FOOD SERVICE MEASURE PRESCRIPTIVE RECOMMENDATIONS Continuation of the current program for commercial freezers and refrigerators is recommended, without need for alteration. 11 of the 13 evaluated new measures are recommended for post-purchase prescriptive incentive delivery under the FinAnswer Express program using deemed savings and costs. Post-purchase prescriptive incentives are not recommended for the Variable Speed Control of Vent Hood Make-Up Air Unit (MAU) or Vent Hood Variable Speed Control with Electric Space Heat measures for the following reasons:  Neither ENERGY STAR nor CEE has a recommended high-efficiency requirement for these measures,  Few utilities offer incentives and the incentive amounts vary widely and are eligibility criteria is relatively undefined,  Wide size variation in each application, and  Limited market penetration. These measures were removed from further analysis and not included in the balance of this section. Table 6-7 contains a summary of the food service measure prescriptive recommendations.

The constantly changing nature of efficiency regulations for food service equipment at the state and federal level, coupled with ongoing updates to specifications published by ENERGY STAR and CEE will require that PacifiCorp revisit eligibility criteria, measures costs and incentive levels on a regular basis to insure that standard or code-compliant equipment does not become eligible for incentives. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-1 Section 7 HVAC 7.1 HVAC CATEGORY OVERVIEW Heating, Ventilation and Air-Conditioning (HVAC) systems are the largest consumers of energy in the commercial building sector (2007 Building Energy Databook). An extremely large installed base of older, less-efficient units and the high peak demand savings resulting from replacement with higher-efficiency units have made HVAC systems a common component of Utility DSM programs. Rising awareness of energy costs, coupled with more stringent energy codes and development of more efficient HVAC systems, has led to rapid change in the sector. Periodic evaluations of the cost-effectiveness and eligibility of current and potential measures to include in future programs is necessary. The following measures are included in the HVAC category for review and analysis. Table 7-1.

Either alone or in combination with a heating plant, the functions are to provide air-circulation, air cleaning, cooling with controlled temperature and dehumidification, and may optionally include the function of heating and/or humidifying.” The definition of unitary commercial air conditioners encompasses both split-system and package configurations of varying capacities which can be air-cooled, water-cooled, or evaporatively-cooled. ARI test standard 210/240-2006 defines an efficiency test standard and certification program for units with rated capacity less then 65,000 btu/hr. ARI test standard 340/360-2007 defines an efficiency test standard for units with rated capacity greater than 65,000 btu/hr but defines a certification program only for units with rated capacity less than 250,000 btu/hr. The ARI definition for Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-2 unitary commercial air-conditioners is consistent with but more narrowly defined than federal code (10 CFR Part 431.92).  Unitary Air-Source Heat Pumps: A unitary air-source heat pump is defined by ARI test standard 210/240-2006 as “One or more factory-made assemblies which normally include an indoor conditioning coil(s), compressor(s), and outdoor coil(s), including means to provide a heating function. The assemblies shall provide the function of air heating with controlled temperature, and may include functions of air-cooling, air- circulating, air-cleaning, dehumidifying or humidifying.” ARI test standard 210/240- 2006 defines an efficiency test standard and certification program for units with rated capacity less then 65,000 btu/hr. ARI test standard 340/360-2007 defines an efficiency test standard for units with rated capacity greater than 65,000 btu/hr but defines a certification program only for units with rated capacity less than 250,000 btu/hr. Air- source heat pumps are defined and treated separately from water-source, ground-water source, and ground-source heat pumps.  Water-Source Heat Pumps: A water-source heat pump is defined by ARI test standard 320-1998 as “One or more factory-made assemblies which normally include an indoor air-conditioning coil with air moving means, compressor(s) and refrigerant-to-water heat exchanger(s), including means to provide both cooling and heating or cooling only functions. A water-source heat pump is typically one of multiple units using fluid circulated in a common piping loop as a heat source/heat sink that is mechanically controlled. Water-source heat pumps shall provide the function of air-circulating and cooling and heating with controlled temperature, and may include the functions of water heating, air-cleaning, dehumidifying and humidifying.”  Ground Water-Source (Geothermal Open-Loop) Heat Pumps: A ground water-source heat pump is defined by ARI test standard 325-1998 as “One or more factory-made assemblies which normally include an indoor air-conditioning coil with air moving means, compressor(s) and refrigerant-to-water heat exchanger(s), including means to provide a heating function and may include a cooling function. A ground water-source heat pump typically uses water pumped from a well, lake or stream as a heat source/sink. Ground water-source heat pumps shall provide the function of heating with controlled temperature, and may include the functions of water heating, air-cooling, air-circulating, air-cleaning, dehumidifying or humidifying.” ARI references ISO 13256-1 as a test standard for determining the unit efficiency. Ground water-source heat pumps are also referred to as geothermal open-loop heat pumps.  Ground Source (Geothermal Closed-Loop) Heat Pumps: A ground source heat pump (GSHP) is defined by ARI test standard 330-1998 as “One or more factory-made assemblies which normally include an indoor air-conditioning coil with air moving means, compressor(s) and refrigerant-to-water heat exchanger(s), including means to provide both cooling and heating, cooling only or heating only functions. A GSHP typically uses fluid circulated through a closed subsurface piping loop as a heat source/sink. GSHPs shall provide the function of air-circulating, cooling and heating with controlled temperature, and may include the functions of water heating, air-cleaning, dehumidifying or humidifying.” ARI references ISO 13256-1 as a test standard for Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-3 determining the unit efficiency. GSHPs are also referred to as geothermal closed-loop heat pumps. In cases where refrigerant is circulated directly into the ground loop rather than using a heat transfer fluid, the systems are referred to as direct expansion geothermal heat pumps. Direct expansion geothermal heat pumps are subject to ARI test standard 870 rather than ISO 13256-1 like other ground-source heat pumps.  Package Terminal Air-Conditioners and Heat Pumps: The definition of a Package Terminal Air-Conditioner (PTAC) is defined in ARI test standard 310/380-2004: “Packaged terminal air-conditioner means a wall sleeve and a separate un-encased combination of heating and cooling assemblies specified by the manufacturer and intended for mounting through the wall. It includes refrigeration components, separable outdoor louvers, forced ventilation, and heating availability by purchaser’s choice of, at least, hot water, steam, or electrical resistance heat.” Package Terminal Heat Pumps (PTHP) are defined similarly in ARI 310/380-2004: “Packaged terminal heat pump means a separate un-encased refrigeration system installed in a cabinet having a function and configuration similar to that of a packaged terminal air-conditioner. It uses reverse cycle refrigeration as its prime heat source and should have other supplementary heat source(s) available to purchasers with the choice of, at least, hot water, steam, or electrical resistance heat.” These definitions are consistent with federal code (10 CFR Part 431.92)  Evaporative Cooling: The California Appliance Efficiency Regulations defines an evaporative cooler as “an appliance that cools indoor air directly or indirectly by evaporation of water.” A direct evaporative cooler means “a heat and mass transfer device used to adiabatically cool air passing through the device by the process of evaporating water directly exposed to this air.” An indirect (two-stage) evaporative cooler means “a heat and mass transfer device used to sensibly cool a primary air stream, without addition of moisture, by means of an evaporatively cooled secondary air stream.”  Programmable Thermostats: Programmable thermostats are defined by ENERGY STAR as “a device that enables the user to set one or more time periods each day when a comfort setpoint temperature is maintained and one or more time periods each day when an energy-saving setpoint temperature is maintained. A programmable thermostat may be capable of controlling one or more zones of a conditioned space.” To qualify as an ENERGY STAR programmable thermostat, the thermostat “shall have at least two different programming periods and at least four possible temperature settings and shall be pre-programmed so the day and sleep time periods are at least 8 hours long.”  Chillers: ARI Test Standard 550/590-2003 defines a water-chilling package (henceforth referred to as a chiller) as “A factory-made and prefabricated assembly of one or more compressor, condensers, and evaporators, with interconnections and accessories, designed for the purpose of cooling water. It is a machine specifically designed to make use of a vapor compression refrigeration cycle to remove heat from water and reject the heat to a cooling medium, usually air or water.” Chiller types include centrifugal, rotary, screw, scroll, reciprocating, and gas absorption. Absorption chillers are subject to a different ARI test standard and not reviewed as part of this analysis. Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-4  Occupancy Based PTHP/PTAC Control: Packaged terminal heat pumps (PTHP) and packaged terminal air conditioners (PTAC) are commonly installed in the hospitality industry to provide heating and cooling of individual guest rooms. Occupancy based PTHP/PTAC controllers are a combination of a control unit and an occupancy sensor that operates in conjunction to provide occupancy controlled heating and/or cooling. The control unit is operated by an occupancy sensor that is mounted in the room and turns the PTHP/PTAC on/off and/or sets back the zone temperature when the room is unoccupied.  Indirect/Direct Evaporative Cooling: ASHRAE defines an indirect/direct evaporative cooler (IDEC) as follows: “In a two-stage indirect/direct evaporative cooler, a first stage indirect evaporative cooler lowers both the dry and wet bulb temperature of the incoming air. After leaving the indirect stage the supply air passes through a second-stage direct evaporative cooler.” Where the design requires a supply air temperature lower than that attainable using indirect/direct evaporative cooling, a third cooling stage (either a direct expansion refrigeration unit or a chilled water coil) can be installed. Generally, IDEC systems are used in large buildings with central air handling systems but can also be found as part of smaller packaged units.  Portable Classroom Control: Three types of controls can be installed in new portable classrooms and retrofitted in existing portable classrooms: (1) 365 day programmable thermostats, (2) occupancy sensor damper control for the ventilation system, and (3) occupancy sensor lighting control. Only 365-day programmable thermostats are reviewed as part of this analysis. 7.2 HVAC MEASURE TECHNOLOGY REVIEW The following core resources were reviewed for information regarding new and existing HVAC measures. The information findings are summarized in Table 7-2. Table 7-2.

The Consortium for Energy Efficiency (CEE) has developed above-code efficiency tiers for different sizes of air conditioners (air-, water- and evaporative-cooled) and heat pumps (air and water-cooled). Approximately 20% of air-cooled air-conditioning units sold in the United States surpass the minimum efficiency criteria for CEE Tier 1, 10% for Tier 2 and less than 1% for Tier 3. Extremely limited quantities of water- and evaporative-cooled air conditioners and air-source heat pumps over 65,000 Btu/hr meet the CEE Tier 1 criteria. The DEER database contains incremental cost information for HVAC systems that generally meet the CEE Tier 1 criteria. ENERGY STAR qualifies air-source heat pumps and air conditioners up to 20 tons that meet the CEE Tier 1 criteria. Peak demand and energy savings estimates are highly dependent on location. Therefore, standard calculations based on the EER and IPLV/SEER and climate data are used to generate savings estimates.  Package Terminal Air Conditioners and Heat Pumps: Relatively little information is available regarding PTAC and PTHP units. The units are most commonly installed in hotel rooms to allow individual occupant control of the space temperature and are normally replaced only upon unit failure. ARI certifies the efficiency ratings of both PTAC and PTHP units. These units must comply with both federal appliance standards and state energy codes. Incremental costs for various unit sizes are available in the DEER database.  Evaporative Cooling: The most useful source for information on evaporative coolers was the Southwest Energy Efficiency Project (SWEEP). This resource compiled market surveys and policy proposals for increasing the prevalence of evaporative coolers in Western states in 2004 and conducted a workshop on the technology in the summer of 2007. SWEEP estimates that the most advanced evaporative coolers are 4-5 times more efficient than a 13 SEER central air conditioner in residential applications. Generally, commercial applications for evaporative cooling systems are limited to large warehouse, storage, or shop areas. However, two-stage indirect/direct evaporative coolers are a common feature of larger central air handling systems in commercial buildings in dry climates. The DEER database provides incremental costs estimates for indirect evaporative coolers used in commercial applications. Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-6  Programmable Thermostat: ENERGY STAR qualified thermostats, which require at least two different programming periods (i.e. weekday/weekend) and four temperature settings have become standard equipment in both new construction and retrofit applications. However, realized energy savings are highly dependent on the setback temperature and schedules employed by individual commercial customers. The ENERGY STAR specification is set to be revised in 2009, effective on January 1st, 2010. If agreement is reached, the new specification is expected to address the disparity between estimated savings and realized savings resulting from improper thermostat programming by focusing on improved usability and consumer education to promote more effective use of the energy saving features. If a revised specification is not released by January 1st, 2010, the ENERGY STAR label will not be available for programmable thermostats at that time.  Chillers: Most of the resources reviewed contained general cost, savings, and equipment lifetime information for chillers. Incremental cost summary data can be found in Appendix B. Savings estimates vary tremendously with chiller type, location, and source and, therefore, were not compiled. The DEER database provided the most complete incremental cost data for a variety of chiller types and sizes. An analysis of the market level savings and cost data for variable speed chillers was generated by RTF. Market level savings potential and costs for the installation of high-efficiency chillers were compiled for both the 2007 PacifiCorp Systemwide DSM Study and 2006 Xcel Energy Colorado DSM Market Potential Assessment.  Occupancy Based PTHP/PTAC Control: Relatively little supplementary cost, savings or measure life data was found in the primary resources reviewed. The DEER Database provides costs data for HVAC time clocks, building energy management systems and programmable thermostats but nothing for occupancy based PTHP/PTAC controls. The 2007 PacifiCorp Systemwide DSM Study analyzed the measure and determined that an occupancy based PTHP/PTAC control saves 25% of the energy used by a system without a controller. Major manufacturers of the controllers are ENERNET Corporation, Smart Systems International, InnCom International and Energy Products, LLC.  Ground-Source/Geothermal Heat Pumps: The Geothermal Heat Pump Consortium (GHPC) and the Northwest Energy Efficiency Alliance (NEEA) were the most useful resources reviewed. Costs for ground-source heat pumps are highly variable depending on the location, ground characteristics, type of system (open-loop and closed-loop) and configuration (ground-only or hybrid). Installation of the ground loop constitutes the largest portion of the total system cost and can range from $300 to more than $1,000 per ton of capacity. ASHRAE has only published recommended efficiency criteria for closed and open-loop ground-source heat pump systems less than 135,000 btu/hr despite the availability of larger systems. ENERGY STAR certification is available for open-loop, closed-loop and direct expansion systems smaller than 135,000 btu/hr. Equipment lifetimes for GSHP systems are considerably longer than standard HVAC equipment, ranging up to 30 years. Peak demand and energy savings estimates are highly dependent on the entering water temperature (EWT). Therefore, standard calculations based on the Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-7 EWT, EER and climate data are used to generate estimates. A review of cost-recovered Energy FinAnswer projects showed that average costs for GSHP systems ranged from $550 to more than $1,700 per ton of installed capacity. Savings were between 180 and 2,347 kWh per ton of installed capacity when compared to a multizone code-compliant rooftop air conditioning system.  Indirect/Direct Evaporative Cooling: SWEEP was the most comprehensive source for information about indirect/direct evaporative cooling systems. Utilized primarily in larger commercial buildings (i.e. offices, event centers, airports, etc.), these systems are estimated to be nearly 3 times as efficient as a mechanically cooled system. IDEC systems are custom designed for particular buildings and generally are installed only as part of new construction projects. Typical costs for IDEC systems, analyzed as part of the Energy FinAnswer program, ranged from $0.50 to $1.50 per CFM of capacity. Energy savings ranged from 0.55 to 1.81 kWh/yr per CFM of capacity and peak demand savings ranged from 0.0001 to 0.0006 kW/mo per CFM of capacity.  Portable Classroom Control: The energy efficiency of portable classrooms has been researched extensively to identify cost-effective energy savings opportunities (Davis Energy Group, WSU Extension Energy Program). Outside of envelope measures, improper scheduling of the HVAC and ventilation system was noted as a significant problem in portable classrooms. Where manual on/off switches are employed, cooling/heating units commonly run when classrooms are unoccupied (summer vacation and weekends). Even when programmed correctly, 7-day thermostats operate cooling/heating units during the unoccupied summer months unless reprogrammed by facility staff at the beginning of summer vacation. To improve scheduling of HVAC systems, the Northwest Portable Classroom Project recommends a 365/366 day programmable thermostat with temporary manual override be installed and configured in all portable classrooms. 7.3 UTILITY HVAC DSM PROGRAM REVIEW The primary utility companies were reviewed for the presence of HVAC measures in their incentive programs. Table 7-3 identifies which utilities offer non-residential customers a prescriptive incentive for the evaluated HVAC measures. Complete utility program information, including incentive amounts and eligibility information can be found in Appendix C. Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-8 Table 7-3.

In most cases, minimum efficiency requirements match the requirements of CEE Tier 1. For units smaller than 65,000 Btu/hr, Alliant, Idaho Power, Seattle City Light, and Xcel Energy have matched minimum eligibility requirements to CEE Tier 2. Most utilities offer a fixed incentive ranging between $25 and $75 per ton for a unit that meets the minimum eligibility criteria of the program. Furthermore, most utilities offer an additional incentive for surpassing the minimum efficiency required by the program. This incentive is calculated based on the actual EER/IPLV of the unit compared to the required minimum EER/IPLV. Seattle City Light provides incentives for any unit that surpasses the minimum efficiency required by the Washington State energy code and pays an incentive based on the calculated kWh saved. The incentives offered by the Energy Trust of Oregon are different for retrofit and new construction projects.  Water and Evaporatively-Cooled Air Conditioners: Only Nevada Power, Seattle City Light, Pacific Power and Rocky Mountain Power have prescriptive offerings for water and evaporatively-cooled air conditioners. Incentives range from approximately $25 to $50 per ton. Eligibility requirements for all programs are identical to the CEE Tier 1 requirements, except for Seattle City Light which provides incentives for any unit with efficiency higher than required by the Washington State energy code. Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-9  Water-Source Heat Pumps: Incentives for water-source heat pumps are offered by approximately half of the reviewed utilities. Heat pump sizes are limited to 25 tons or less with larger sizes requiring pre-approval or a custom incentive. Minimum efficiency requirements vary between the utilities, especially for units larger than 135,000 btu/hr since CEE and ASHRAE do not provide suggested minimum efficiencies. Incentives range between $30 and $50 per ton. ETO only provides incentives for new construction projects in the amount of $200 per ton.  Package Terminal Air Conditioners and Heat Pumps: Incentive programs for PTAC and PTHP units are offered by four utilities and minimum efficiency requirements and incentive structures vary widely. Most utilities mandate a standard minimum efficiency for all unit sizes to qualify for an incentive. Nevada Power requires a PTAC or PTHP to be 20% more efficient than the federal standard. Incentives have either a flat rate per qualifying unit or an incentive per ton based on the EER. Seattle City Light pays $0.20 per kWh saved for units with higher efficiency than required by the Washington State energy code.  Evaporative Cooling: Incentives are only offered by PG&E and Idaho Power for indirect or direct evaporative cooling units. Incentives are available only for systems that replace an existing air-conditioning unit and ranged between $200 and $300 per unit depending on the type of evaporative cooler installed. The FinAnswer Express program pays $0.02/CFM which is approximately $260 for a 10-ton unit.  Programmable Thermostats: Programmable thermostats were common among reviewed utility DSM programs. In all cases, the eligibility requirement to receive an incentive mandated that the thermostat be at least ENERGY STAR qualified or have temperature set-back and scheduling capabilities more stringent than an ENERGY STAR qualified thermostat (i.e. 7-day programming and optimum-start based on occupancy/outside air temperature). Incentives ranged from $25 to $50 per thermostat among the programs. Only the FinAnswer Express program had separate incentive amounts depending on whether the thermostat was installed on a heat pump ($70) or an air-conditioner ($25). Incentives for programmable thermostats were discontinued by PG&E in 2006 and SMUD at the beginning of 2008.  Chillers: Nearly half of the reviewed utilities offered incentives for electric air and water-cooled chillers. Minimum eligibility requirements vary with the heat rejection source, compressor type, and size of the chiller. All programs prohibited back-up chillers from receiving incentives. The Wisconsin Focus on Energy Program, APS, Seattle City and Light, and Xcel Energy offer customers a fixed incentive per ton of chiller capacity for meeting a minimum kW/ton efficiency rating and an additional incremental incentive per ton for chillers with higher efficiencies. ETO provides incentives at a flat rate of $50 per ton for new construction projects only. Additional information about utility chiller incentive programs, including minimum eligibility requirements and incentive amounts can be found in Appendix C.  Occupancy Based PTHP/PTAC Control: Xcel Energy, Nevada Power, and the Wisconsin Focus on Energy program offer incentives for installing occupancy based PTAC/PTHP controls. Nevada Power and Focus on Energy offer $55 and $75 incentives Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-10 per room/sensor, respectively. Xcel Energy pays incentives based on energy savings for occupancy based PTHP/PTAC controls through its custom incentive program. For these programs, the controller is required to sense the occupant using heat, motion, or door-key activation. PTAC/PTHP controls that are solely front desk-activated (i.e. front desk controls unit based on check-in/check-out times) did not qualify in any programs.  Ground-Source/Geothermal Heat Pumps: Incentives for commercial customers installing GSHP were offered by Alliant Energy and the Energy Trust of Oregon. Additionally, BPA has provided large incentives for residential customers of member utilities, but has no established program for commercial customers. Alliant Energy provides incentives for open-loop and closed-loop system types in both retrofit and new construction projects. ETO provides incentives for closed-loop systems in new construction projects. Sizes are limited to 20 tons or smaller for prescriptive incentives. Since CEE does not publish suggested minimum efficiencies for GSHPs, eligibility criteria have been matched to ENERGY STAR certification criteria for open-loop and closed-loop systems up to 20 tons in size. Incentive structures vary between the utilities. Alliant provides an incentive of $300 per ton for the installation of a ground loop up to 20 tons and $150 per ton for a qualifying heat pump unit. ETO offers a flat incentive of $300 per ton up to 10 tons for qualifying GSHPs.  Indirect/Direct Evaporative Cooling: No reviewed utilities offered prescriptive incentives for an indirect/direct evaporative cooling system.  Portable Classroom Control: Only one utility offered incentives for 366-day programmable thermostats used in portable classrooms. Puget Sound Energy (PSE) estimates that a single 366-day programmable thermostat saves 3,550 kWh/yr when used in a portable classroom. PSE provides an incentive of up to $250 dollars for installing a qualifying unit. Pre-approval is required before equipment is installed. The majority of utility programs reviewed have formed a trade alliance of qualifying vendors to market the post-purchase incentives to customers while trade alliance involvement varies. Most utilities have trained a group of contractors about the incentive programs and provide a list of qualifying alliance members to their customers. Alliant Energy maintains a comprehensive web site devoted to trade allies and associates. The website contains current program information, marketing and trade show financial assistance, and professional training incentives. PG&E also maintains a website and provides a searchable database of participating vendors. The database is organized by market segment (industrial, residential, commercial), market area, and specific technology. Nearly all utilities have developed a custom track to provide for any project that does not fall within the scope of existing prescriptive incentive program guidelines. Custom projects involve pre-approval from the utility/program managers and pay based on the estimated energy savings. 7.4 HVAC MEASURE CODE REVIEW A review of state and federal codes applicable to existing and potential HVAC measures was conducted. The minimum efficiency criteria for each type and capacity of HVAC equipment in Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-11 UT, ID, WA, and CA and the minimum efficiency standards set by the federal government can be found in Table 7-4 and Table 7-5.

Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-13  Air-cooled Air Conditioners and Heat Pumps: Federal efficiency standards mandate minimum efficiency requirements for all air-cooled air-conditioners and heat pumps smaller than 240,000 Btu/hr (10 CFR Part 431.97, 10 CFR Part 430.92). Federal standards specify minimum efficiency criteria by system type (split-system or package), cooling capacity, and electric phase (1 or 3 phase). In almost all cases, state energy codes match the minimum federal requirements and CEE Tier 1 requirements for sizes less than 65,000 Btu/hr. State codes match ASHRAE 90.1-2004 for larger sizes. The Energy Independence and Security Act of 2007 mandates that efficiency standards for 3-phase central air conditioners and heat pumps less than 65,000 Btu/h will increase to 13 SEER on June 16, 2008. Federal standards for the remaining regulated equipment will increase on January 1, 2010 to match CEE Tier 1 efficiency criteria. Also on January 1, 2010, previously unregulated federal standards for air-cooled air conditioners and heat pumps ranging between 240,000 and 760,000 Btu/hr will go into effect. Codes in UT and ID, will have to be increased to match these higher minimum efficiency requirements. The Washington State energy code and California Title 24-2008 already contains provisions to increase minimum efficiency requirements to match the federal standards on January 1, 2010.  Water and Evaporatively-Cooled Air Conditioners: Each state’s energy code specifies minimum efficiency criteria meeting ASHRAE 90.1-2004 for all sizes of water and evaporatively-cooled air conditioners. Federal standards exist only for units less than 240,000 Btu/hr. California adheres to the federal code for sizes less than 240,000 Btu/hr, and meets ASHRAE 90.1-2004 for larger sizes. No code changes in the minimum efficiency criteria for water or evaporatively-cooled air conditioners are expected at the state level. Federal efficiency criteria are set to expire on January 1, 2010.  Water-Source Heat Pumps: Efficiency standards for water-source heat pumps less than 135,000 btu/hr are identical in UT, ID, WA and federal code and match ASHRAE 90.1- 2004. No standards exist for units larger than 135,000 Btu/hr. California code provides no direct efficiency provisions for water-source heat pumps and is pre-empted by Federal standards. No code changes are anticipated for water-source heat pumps at the state level. Federal efficiency criteria are set to expire on January 1, 2010.  Package Terminal Air Conditioners and Heat Pumps: Federal appliance efficiency standards exist for PTAC and PTHP units that fall into any of the following size categories: <7,000 Btu/hr, 7,000 to 14,999 Btu/hr, and ≥15,000 Btu/hr. A formula is used to calculate the minimum efficiency requirement (EER and COP) based on unit capacity. State energy codes specify minimum efficiency requirements significantly higher than federal code that match ASHRAE 90.1-2004. State minimum efficiency requirements for units installed in new construction projects are more stringent than for replacement units. A formula based on unit capacity is used to calculate the minimum efficiency requirements and is listed in Table 7-6. Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-14 Table 7-6.

Cap means the rated cooling capacity of the product in Btu/hr. If the unit’s capacity is less than 7,000 Btu/hr, use 7,000 Btu/hr in the calculation. If the unit’s capacity is greater than 15,000 Btu/hr, use 15,000 Btu/hr in the calculation. b. Test procedure for all efficiency ratings is ARI 310/380 at 95°F db outdoor air condition.  Evaporative Cooling: Neither direct nor indirect evaporative coolers are regulated by state or federal energy codes.  Programmable Thermostats: IECC 2006 and the Washington State energy code require that all new space-conditioning systems have a programmable thermostat with 7- day programmable thermostatic setback capabilities, 10-hour battery backup, and a manual 2-hour override feature. Title 24 of California Code requires similar features but describes a larger number of exceptions based on building type and use.  Chillers: Water chilling packages are subject to minimum efficiency requirements as part of the energy codes in UT, WA, ID and CA, as listed in Table 7-7 minimum COP requirements are identical across all four states, but minimum IPLV requirements are significantly higher in WA and CA when compared to UT and ID (IECC 2006). No federal regulations pertain to water chilling packages. Table 7-7.

The requirement can be met by a standard add-on or integral programmable thermostat. In addition, each state stipulates that a controller that shuts off the unit during periods of non-use as determined by an occupancy sensor can meet the requirement. However, none of the codes reviewed in UT, WA, ID or CA directly required occupancy based controls for PTAC/PTHP units.  Ground-Source/Geothermal Heat Pumps: State energy codes in UT, WA, ID and CA specify minimum efficiency criteria for both open-loop and closed-loop ground-source heat pumps that meets ASHRAE 90.1-2004. No federal standards exist for GSHPs. Environmental codes and permits from state governments or the EPA may be necessary for open-loop, GSHP systems.  Indirect/Direct Evaporative Cooling: Similar to evaporative cooling systems, no appliance or energy codes at the state or federal level pertain directly to an IDEC system. State energy codes in all four states mandate that any fans employed in a variable air volume system greater than 10HP have an installed variable speed drive. This limits “pump motor demand to no more than 30% of design wattage at 50% of design air volume for fans when static pressure set point equals 1/3 the total design static pressure.”  Portable Classroom Controls: Additional portable classroom controls above those required by the standard provisions of the energy code in each state (e.g. 7-day programmable thermostats) are not required. Proposals have been made in the past to add requirements to the energy code for portable classrooms given their unique characteristics compared to other building types but no additional stipulations have been enacted. A summary of the current and expected code requirements for HVAC measures is presented in Table 7-8.

Portable Classroom Control (365/366 Day Thermostat) Vendors Vendor Phone Number Mark Ridick @ Proliphix (MA) (978) 692-3375 x112 Tami Anderson @ RSD Total Control (WA) (509) 838-0593 Scott Laing @ ThermoPros (CA) (916) 933-0443 Joe Montrone @ TCS Basys (UT) (801) 487-7741 As part of this evaluation, Nexant surveyed these vendors and others to gauge current market awareness and trends associated with potential prescriptive measures. Some key feedback received included:  Currently, portable classrooms are the primary market for 365/366 day thermostats. This is because HVAC systems are either manually controlled or include 7-day thermostats that are not reconfigured for summer vacation and major holidays. One vendor has had Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-17 some success marketing the thermostats as “energy management solutions” to commercial customers.  Vendors commented that incentives are extremely helpful to schools because energy efficiency projects must be budgeted on a long-term basis. Money is usually not available when districts examine installing 365/366 day thermostats.  Generally, portable classroom controls are sold direct to school districts and all the portables are retrofitted at once. There is fairly limited product availability of 365/366 day portable thermostats with 3-4 major brands. Each provides a distinct feature set slightly different from others, but contains the capability to provide 365/366 day scheduling.  Multiple vendors noted that the commercial sector, especially buildings with 24/7 load profiles (i.e. casinos, ice rinks, pools/spas, hospitals, etc.) and schools, are a prime target for GSHP systems, Two vendors expressed surprise that more schools are not looking at GSHP systems. Adding ground loops to existing buildings in urban areas is sometimes difficult. However, new construction projects are good opportunities since upfront costs can be lowered by piggybacking on existing excavation efforts.  One vendor noted that system designers are commonly inexperienced, leading to disagreements with the installer/contractors and/or poorly sized ground loops. It was suggested that only experienced and/or certified designers should be working with GSHP systems.  The largest up-front cost for a ground-source system is the excavation/drilling to bury the ground loop. Multiple vendors noted that lower ground-loop costs would significantly boost GSHP installations. Based on past experiences, multiple vendors said that incentive programs have had varying levels of success when attempting to deter the cost of the ground-loop. Also, one noted that prescriptive program offerings are rare but has worked with utilities on “custom” GSHP projects that require energy modeling. 7.6 PRESCRIPTIVE RECOMMENDATIONS The current FinAnswer Express incentive program HVAC measures were reviewed to determine changes to the eligibility requirements, deemed savings, and/or incentive amounts. The majority of HVAC measures should be maintained with existing eligibility requirements and incentive levels through the end of 2009 cooling season. While the size categories of PTAC/PTHP incentives used in the existing FinAnswer Express program differ from those categories used in state and federal codes and other utilities, the existing categories and minimum efficiency criteria should remain unchanged. Previously, Nexant examined the PTAC market for PacifiCorp and identified the existing size categories and minimum efficiency criteria. Only one change to the existing FinAnswer Express program for HVAC measures is recommended: Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-18  Reduce the incentive for programmable thermostats installed on heat pumps from $70 per unit to $50 per unit to match amounts offered by other utility programs. Table 7-11 contains a summary of the measures recommended for inclusion in the prescriptive incentive program. The existing HVAC trade ally network will be leveraged to facilitate the distribution of additional measures and the scope of membership will be broadened to include GSHP installers and designers. Of the three potential HVAC measures reviewed, two, GSHPs and 365/366 day thermostats in portable classrooms, are recommended for post-purchase prescriptive incentive delivery under the FinAnswer Express program. Separate incentives should be offered for the installation of a ground loop and ENERGY STAR qualified GSHPs. Post-purchase prescriptive incentives with deemed savings and costs are not recommended for indirect/direct evaporative cooling system at this time because:  Each unit is custom designed and built, based on the local weather and building characteristics  There are few installations per year because IDEC systems are installed exclusively in large, new construction projects  Verification of proper installation and commissioning is necessary to verify demand and energy savings For fully-commissioned IDEC systems, a simplified analysis based on the existing chiller tool (Section 7.9) will be used to calculate the savings and costs will be determined from actual project costs. The tool will be designed to calculate energy and peak demand savings per average air flow rate. On January 1, 2010, federal and state codes for commercial air-cooled HVAC equipment will increase to match the existing incentive program. At that time eligibility requirements and eligibility levels should be increased to match CEE Tier 2 requirements. Existing incentive levels and eligibility requirements for 3-phase central air conditioners and heat pumps less than 65,000 Btu/hr should be maintained through the current program year and then increase in 2009 to match the CEE Tier 2 requirements. It is recommended that the existing incentive structure be expanded to include higher incentives for units that meet CEE Tier 2 or Tier 3 efficiency criteria. This is recommended to encourage adoption of higher efficiency equipment prior to January 1, 2010, position the utility incentive programs for the change, and prepare vendors and customers. Nearly 10% of the units listed in the ARI database currently meet CEE Tier 2 requirements and broader availability is expected as federal and state codes become more stringent. The existing eligibility requirements and incentive levels for CEE Tier 1 qualifying HVAC equipment (except for 3-phase air conditioners and heat pumps smaller than 65,000 Btu/hr) should remain unchanged until January 1, 2010. Additionally, ARI Standard 340/360-2007 for unitary air-conditioners and heat pumps >65,000 Btu/hr contains provisions to phase out IPLV ratings on December 31, 2009 in favor of the Integrated Energy Efficiency Ratio (IEER) rating. In contrast to the IPLV rating, the IEER rating conditions are not fixed temperatures across all load conditions, but vary depending on the part load condition. As all equipment manufacturers, the ARI database, and the applicable Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-19 energy code (IECC 2006) currently utilize IPLV ratings, it is not clear how this change will immediately affect equipment ratings in the marketplace. FinAnswer Express should continue to maintain rating criteria consistent with that used by effective energy code in the State of Idaho (IECC 2006). Table 7-11 contains a summary of the HVAC prescriptive measure recommendations. Table 7-11.

The baseline for ground-source heat pumps is an equivalently sized air-source heat pump that meets the minimum equipment efficiency established by current codes. Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-20 The baseline for 365/366 day programmable thermostats in portable classrooms is a standard code-compliant portable classroom with a 7-day programmable thermostat with identical settings throughout the year. The baseline for an indirect/direct evaporative cooling system shall be specified by ASHRAE 90.1-2004 – Informative Appendix G. For all other evaporative cooling measures, the baseline shall be a code-compliant unitary commercial air-conditioning unit of comparable size that meets the required cooling load. 7.8 MINIMUM ELIGIBILITY REQUIREMENTS FOR HVAC MEASURES Recommended minimum efficiency requirements for the proposed HVAC measures are summarized in Table 7-12. Eligibility requirements for measures already included in the FinAnswer Express program should remain unchanged, except as noted in Section 7.6. Table 7-12. HVAC Measure Minimum Efficiency Recommendations Measure Subcategory Recommended Minimum Efficiency Requirements Unitary Air-Cooled AC 3-phase, All Sizes CEE Tier 2 or 3 Unitary Air-Source HP 3-phase, All Sizes CEE Tier 2 or 3 Ground-Source HP All Types & Sizes ENERGYSTAR qualifying unit 365/366-day Prog. Thermostats Only in Portable Classrooms 365/366 day thermostatic setback capability. Must be installed in a portable classroom that is unoccupied during the summer months. 7.9 HVAC MEASURE UNIT COSTS, SAVINGS AND RECOMMENDED INCENTIVES Estimated measure life for the HVAC measures were matched to the values used in the DEER database, except for GSHP units. These units were based on the RTF recommendation for residential GSHP systems. Unit costs for unitary HVAC equipment were based on data obtained from Xcel, PG&E, the DEER database, and information supplied by commercial vendors. Data obtained from the Ground-Source Heat Pump Consortium and GSHP installers was used to generate unit cost estimates for GSHP systems. Costs for 365/366 day programmable thermostats were directly obtained from vendors. Since all HVAC measures are weather sensitive, energy savings were calculated using both the weather data from each state and the incremental improvement in efficiency between incentive qualifying units and code-compliant units. An energy simulation was developed to estimate energy savings associated with upgrading to a 365/366 day programmable thermostat in portable classrooms.

The estimated net-to-gross ratio is 0.80 for these measures. 3 Minimum efficiency required by code for heat pumps in CA, ID, UT is 10 SEER, and 13 SEER in WA. The majority of IDEC systems are installed as part of new construction projects in select climate zones. These units are installed only when specified by the owner or building designer. To date, IDEC savings and incentive calculations in the Energy FinAnswer program have been calculated using a detailed analysis approach consisting of a whole building energy simulation model. While detailed project-by-project engineering provides the best savings estimates, it is expensive, complex, and time-consuming. However, a properly operating IDEC system can provide considerable energy and peak demand savings compared to a standard direct expansion unit or chilled water coil. A prescriptive approach for calculating and offering incentives for Section 7 HVAC 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 7-22 IDEC systems could reduce administrative costs, improve measure awareness, and simplify building energy cost estimating for new building owners and designers. A simplified savings calculation tool that corrects for the primary independent variables associated with an IDEC system is recommended to balance the value of a prescriptive-option against the additional savings uncertainty associated with simplified savings calculations. The tool will be fundamentally based on the existing chiller tool developed by Nexant for PacifiCorp. Energy savings attributed to adding an indirect coil and direct exchange media as a first and second stage of cooling as compared to a baseline single stage chilled water coil will be calculated. Additional data required from the customer beyond that already required by the chiller tool will include:  Capacity of air-handling system (CFM),  Cooling tower fan/pump motor specifications,  Direct media water pump specifications, and  Total system cost. Methods outlined in ASHRAE 90.1-2004 Appendix G and standard system control parameters and temperature set points based on climate will be utilized in the spreadsheet tool to calculate the gross peak annual energy and demand savings. Incentives will be calculated based on estimated kWh and kW savings similarly to the existing FinAnswer Express chiller tool at rates identical to the Energy FinAnswer program with the commissioning opt-out 20% reduction, equivalent to $0.12/kWh + $50/kW. 7.10 HVAC MEASURE OUTLOOK Based on the currently scheduled issuance of new federal minimum efficiency requirements for large commercial unitary air-conditioners and heat pumps in 2010, PacifiCorp will need to revisit and potentially adjust measure data for 3-phase units. Title 24-2008 and IECC 2009 will be revised before January 1, 2010 and are likely to contain provisions meeting 2010 federal standards for minimum efficiency requirements of HVAC equipment. Additionally, the Energy Independence and Security Act of 2007 provides the authority to the Department of Energy to consider separate regional efficiency standards for furnaces, central air conditioners, and heat pumps. Issuance of regional efficiency standards may require re-evaluation of measure data across the four states in PacifiCorp territory. Additionally, ARI Standard 340/360-2007 for unitary air conditioners and heat pumps sunsets the use of IPLV ratings for units >65,000 btu/hr in favor of an IEER rating to measure the part- load performance of unitary systems. It will be necessary to gauge how quickly the marketplace and energy codes respond to the new rating criteria and adjust eligibility requirements as necessary to replace the IPLV with IEER requirements. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-1 Section 8 Irrigation 8.1 IRRIGATION OVERVIEW Pressurized agricultural irrigation systems use a significant amount of energy. System pumping energy requirements can be reduced by implementing various efficiency measures to control system water leakage and to improve water application. Energy efficiency measures where customer participation and PacifiCorp’s administrative efforts can be streamlined and simplified were identified. Consistency with neighboring utilities and others offering similar energy efficiency services and incentives is also strongly desired. PacifiCorp is already well-engaged in the irrigation market in Idaho through the existing Irrigation Energy Savers program. The program allows irrigators to exchange worn nozzles, gaskets or drains for new equipment at participating dealers and receive incentives for replacing worn pressure regulators, low pressure drains, and sprinkler packages on pivot and linear systems. Given the current and continued success of the Irrigation Energy Savers program in Idaho, offering incentives through the separate FinAnswer Express program is not recommended at this time. The following information and recommendations are to be used for reference at a time when PacifiCorp is prepared to implement additional irrigation measures on a prescriptive basis through the Irrigation Energy Savers program. Table 8-1 summarizes the initial list of potential irrigation measures evaluated in this section. Table 8-1.

Additional measures included in this evaluation are listed in Table 8-2. Table 8-2. Additional Evaluated Irrigation Measures Additional Potential New FinAnswer Express Irrigation Measures New Nozzles for Impact Sprinklers Rebuilt or New Wheel Line Sprinkler Leveler Rebuilt or New Wheel Line Feed Hose 8.1.1 Irrigation Measure Descriptions Detailed descriptions of the irrigation measures identified in Table 8-1 include:  Cut and Pipe Press Repair of Leaking Wheel Lines, Hand Lines, and Portable Mainlines: Worn pipe connections can cause leaks and lead to failure. Typically the connections are replaced with new parts that are pressed on the end of aluminum pipe sections. This measure reduces water leakage from the irrigation system, resulting in reduced pumping demand and energy consumption from pump operation.  Drip Irrigation Systems: Drip irrigation systems can operate at lower pressures and higher application efficiency than typical sprinkler irrigation systems. Reduced energy demand can occur if the drip irrigation system reduces the pumping pressure and/or flow.  Low Pressure Sprinkler Nozzles: Some conventional impact sprinklers with operating pressures above 50 psi can be replaced with other sprinkler types designed to operate at lower pressures. Decreasing the pump’s discharge pressure by trimming the impeller or otherwise modifying the pump can decrease energy demand, resulting in energy savings from the pump operation.  New Center Pivot Base Boot Gasket: The center pivot base gasket can wear and cause significant leaks. Replacing the worn gasket reduces water leakage from the irrigation system, resulting in reduced pumping demand and energy consumption from pump operation.  New Drains for Wheel Lines, Hand Lines, or Pivots: Replacing leaking drains reduces the system flow rate, resulting in reduced pumping demand and energy consumption from pump operation.  New Drop Tube for Low Pressure Pivot Sprinklers: This component is required when converting from overhead sprinklers to lower-pressure drop sprinkler packages. After a sprinkler package conversion, the required pivot operating pressure is typically reduced. With less pressure required from the irrigation system, demand on the pumping equipment can be reduced. Individual replacement of leaking drop tubes reduces flow of the irrigation system, resulting in reduced pumping demand and reduced energy consumption from pump operation. Section 8 Irrigation 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-3  New Flow Controlling Nozzle for Impact Sprinkler: The volume of water distributed by the impact sprinkler can be reduced by installing new flow control type nozzles that replace existing worn brass or flow control nozzles of the same size or less. As a result, less water flows through the irrigation system, resulting in reduced pumping demand and energy consumption from pump operation.  New Gaskets for Wheel Lines, Hand Lines and Portable Mainlines: Replacing leaking gaskets reduces the irrigation system flow rate, resulting in reduced pumping demand and energy consumption from pump operation.  New Gooseneck Elbow for New Drop Tubes: This component is required when converting from overhead sprinklers to lower-pressure drop sprinkler packages. After a sprinkler package conversion, the required pivot operating pressure is reduced. With less pressure required from the irrigation system, demand on the pumping equipment can be reduced. Individual replacement of leaking goosenecks reduces flow from the irrigation system, resulting in reduced pumping demand and energy consumption from pump operation.  New Hubs for Wheel Lines: This measure is specific to Thunderbird brand wheel lines that have a gasket at the hub of each wheel. This measure can reduce the flow rate by fixing leaking hubs, resulting in reduced pumping demand and reduced energy consumption from pump operation.  New Low-pressure Regulators for Pivot Sprinklers: Worn or faulty regulators can result in excessive amounts of water being distributed by each pivot sprinkler. New regulators restore the design pressure and flow for the individual pivot sprinkler. Pumping less water through the irrigation system, results in reduced pumping demand and energy consumption from pump operation.  New Multiple-configuration Nozzles for Low-Pressure Pivot Sprinklers: This measure includes adding a sprinkler nozzle clip and a second nozzle at each drop tube or current sprinkler position. This allows irrigators to switch to smaller nozzles and reduce the average application rate during germination or the early stages of crop growth. Reducing the total center pivot flow results in reduced pumping demand and energy consumption from pump operation.  New Multi-trajectory Spray type Pivot Sprinklers: Replacing worn spray heads or overhead impact sprinklers on center pivots with spray type sprinklers restores the pivot flow to original design conditions. The pivot flow rate with new sprinklers is restricted to the amount specified by existing design conditions. This measure reduces pivot flow rate and improves the application efficiency, resulting in reduced pumping demand and energy consumption from pump operation.  New Rotating-Type Pivots Sprinklers: Replacing worn sprinklers or overhead impact sprinklers on center pivots with rotating type sprinklers restores the pivot flow back to design conditions. The pivot flow rate with new sprinklers is restricted to the amount specified by existing design conditions. This measure reduces pivot flow rate and Section 8 Irrigation 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-4 improves the application efficiency, reducing the pivot flow rate results in reduced pumping demand and energy consumption from pump operation.  Rebuilt or New Brass Impact Sprinkler: Worn impact sprinklers can leak and may not rotate properly. This measure reduces leaks and improves the application efficiency, resulting in reduced pumping demand and energy consumption from pump operation.  New Nozzles for Impact Sprinklers: This measure reduces flow from sprinklers by replacing worn nozzles with new ones of the same flow rate or less. Reducing the flow results in reduced pumping demand and energy consumption from pump operation.  Rebuilt or New Wheel Line Sprinkler Levelers: This measure reduces leaks from worn levelers and can improve sprinkler application uniformity by keeping the sprinkler level. Reducing the flow results in reduced pumping demand and energy consumption from pump operation.  Rebuilt or New Wheel Line Feed Hose: This measure reduces leaks from worn wheel line feed hoses. Reducing the flow results in reduced pumping demand and energy consumption from pump operation. 8.2 IRRIGATION TECHNOLOGY REVIEW Table 8-3 identifies the key informational resources utilized to conduct the irrigation technology review.

These programs include many of the same irrigation equipment measures. BPA’s list of eligible irrigation equipment is very specific to different types of equipment. Idaho Power’s list appears to be a simplified list of BPA’s measures, grouping similar measures together. The primary sources of information for each utility’s program include: Bonneville Power Administration. October 1, 2007. Conservation Rate Credit (CRC) and Conservation Acquisition (CAA) Implementation Manual, Section 5: Agricultural Sector, Pages 36-45. (PDF version downloaded January 2, 2008). Idaho Power, “Irrigation Efficiency Rewards”. December 3, 2007. http://www.idahopower.com/energycenter/energyefficiency/Irrigation/irrigationprogram.htm. (January 16, 2008). Utility program review showing measure savings is located in Appendix B and incentives are included in Appendix C. 8.4 IRRIGATION CODE REVIEW Generally, codes are not applicable to sprinkler equipment. However, standard industry practices and performance guidelines are the baseline. Pump motors are subject to state and federal energy codes (See Section 10). Water rights control the maximum amount of water available for irrigation but do not limit irrigation practices or types of equipment. Section 8 Irrigation 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-7 8.5 IRRIGATION VENDORS Table 8-5 contains contact information for three identified vendors of irrigation equipment within PacifiCorp’s Idaho service territory. Table 8-5. Representative Idaho Irrigation Vendors Vendor Phone Number Knudsen Irrigation (208) 397-4300 Valley Equipment & Irrigation (208) 785-7017 Rain for Rent (208) 522-4500 Golden West Irrigation (208) 524-3203 Twelve irrigation dealers were contacted and surveyed across PacifiCorp’s service territory regarding potential irrigation measures and their suitability in the dealer’s local service areas. These measures were discussed with each dealer and opinion was documented. Dealers provided estimated costs, suggestions for additional measure items, and irrigation equipment program delivery. Also, dealers provided additional information concerning other potential measures and local market acceptance for each measure. A summary of comments made by irrigation dealers is provided below. The vendor survey results can be found in Appendix A.  Irrigators tend to replace or repair relatively low cost equipment when worn, failing, or at the end of useful life. Routine maintenance and repair is more common for higher priced items such as pumps and center pivot sprinkler packages.  Dealers prefer that the irrigator pay for equipment purchased and then submit an application for reimbursement from the utility. Dealers recognize that they may have to help the irrigator fill out paperwork for reimbursement. Any reimbursement is directly sent to the irrigator.  Exchanging equipment can lead to unnecessary handling of used items. Generally, irrigation dealers do not want to be responsible for disposal or recycling of old equipment. An example would be if an irrigator brings in many center pivot sprinkler packages or parts which can equal several pickup loads.  Dealers prefer exchanging pivot components rather than entire sprinkler packages. Rocky Mountain Power’s Idaho program required complete center pivot sprinkler package changes with a minimum number of sprinklers. Many smaller pivots were not eligible.  Utah irrigation dealers are very enthusiastic about participating in an irrigation efficiency program, as one is currently not available through Rocky Mountain Power.  Dealers wish to include the following items in a potential irrigation efficiency exchange program:  Replacement or repair of worn and leaking wheel line feed hoses Section 8 Irrigation 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-8  Include replacement parts for valve openers in the gasket portion of the program. This includes riser caps (dome discs) and seals for valve openers which can leak significantly.  Similarly dealers wish to remove or had very limited interest in the following items:  Potential incentives for conversion to drip irrigation are either not supported or do not apply, because of the limited amount of permanent drip irrigation in Utah, Idaho and Northern California. It is assumed that farmers converting to permanent drip irrigation are motivated by other reasons beyond energy savings such as vineyard development. Based on the irrigation dealer comments, drip irrigation conversion has been removed from the list of recommended prescriptive measures. An irrigator converting to drip could still be eligible for incentives under a custom analysis, if available.  New multiple configuration nozzles (dual nozzles) for pivot sprinkler packages are popular in a few local areas in Washington. Most irrigation dealers indicated that none or a few pivots in their area would participate in this measure. Based on the irrigation dealer’s comments, this individual measure has been removed from the list of recommended prescriptive measures. An irrigator installing a new dual nozzle system may still be eligible for incentives under the standard pivot sprinkler replacement measure. 8.6 IRRIGATION EQUIPMENT PRESCRIPTIVE RECOMMENDATIONS Of the 18 potential irrigation measures investigated, 12 measures are recommended for a post- purchase prescriptive incentive program. The separate measures for rotating type and spray type pivot sprinkler have been combined into a single measure for all types of pivot sprinklers. The separate measures for new drains and new gaskets for wheel lines, hand lines, pivots and portable main-lines have been combined and expanded to include valve opener seals and caps. Multi-configuration nozzles sprinklers will qualify for incentives under the more general category of new pivot sprinkler heads. New drop tubes will only qualify for incentives if sold with a gooseneck elbow or boomback. Drip irrigation systems and new low pressure sprinkler nozzles are not recommended for a separate prescriptive incentive at this time based on feedback from irrigation dealers. These are better suited for a custom analysis. Table 8-6 contains a summary of the recommended measures for inclusion in the prescriptive incentive program. Where appropriate, the list of original measures has been simplified and some measures have been combined into a single measure. In addition to including these measures in the prescriptive incentive program, a formal trade ally network will be assembled to facilitate the distribution of these measures to the customer.

Annual energy savings were calculated using similar methods to the Irrigation Energy Saver’s program, with updated information. Savings by state vary based on the average operating hours and average pumping lift which are displayed in Table 8-9. Gross customer costs are based on material and installation costs provided by irrigation dealers. The estimated net-to-gross ratios are similar to those used by the Irrigation Energy Savers program. Section 8 Irrigation 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-12 Table 8-10 summarizes the key measure information for the recommended irrigation measures for Idaho.

Section 8 Irrigation 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 8-13 8.10 MEASURE CATEGORY OUTLOOK Irrigation equipment measures can have high participation rates for the first year and then drop off to a minimal level in subsequent years. Lately, the market price for hay and grains has increased significantly. As discussed with some irrigation dealers, many farmers may experience higher revenues. With increased revenues, irrigators may be more likely to perform maintenance and make upgrades that previously were not cost effective. This increase in crop revenues may increase program participation and/or extend the program. Material costs for irrigation equipment fluctuates regularly. Material costs for brass and metals are expected to continue to increase. The costs and incentive levels for all measures need to be re-evaluated every few years. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-1 Section 9 Lighting 9.1 LIGHTING CATEGORY OVERVIEW As the most common installation, prescriptive lighting incentives comprise the majority of PacifiCorp’s FinAnswer Express program. To provide knowledge and motivate owners to switch to more efficient fixtures, rebates should reflect the wide assortment of lighting systems that are available on the market. Table 9-1 lists existing FinAnswer Express measures as well as potential new measures. Table 9-1. Evaluated Lighting Measures Existing FinAnswer Express Lighting Measures Potential New FinAnswer Express Lighting Measures All current existing measures were reviewed for possible adjustment. See Appendix C and D for a complete listing. >750 W MH, MV, HPS with 8+ T5 HO lamps + EB Lighting controls Bi-level stairwell, hall and garage fixtures Indoor and outdoor LED channel letter signs Daylighting controls LED message center signs LED case lighting Exit signs (existing) Exit signs (photoluminescent and tritium) 9.1.1 Lighting Measure Descriptions  >750 W MH, MV, HPS with 8+ T5HO lamps + EB: Replace metal halide, mercury vapor or high pressure sodium lamps drawing greater than 750 W with a fixture of at least 8 T5 high output fluorescent lamps controlled by an electronic ballast.  Bi-level stairwell, hall and garage fixtures: Lighting fixtures that are wired to provide 2 or more levels of control and an integral occupancy sensor to allow for reduced lighting when areas are unoccupied. A special electronic ballast may be necessary depending on levels of power, multiple wall switches, or multiple ballasts per fixture. This measure was expanded to include bi-level fixtures installed in any space type.  Daylighting controls: An electronic system containing a photosensor which automatically dims or shuts off lighting when sufficient daylight is present to light the area. The sensor constantly measures ambient light levels and adjusts the lighting accordingly. A special electronic ballast that can constantly regulate the power flow and detailed sampling of light levels is required.  LED case lighting: Replace existing lighting in frozen or refrigerated retail food cases with energy efficient LED light bars.  Existing measure review: Review existing measure incentive levels and customer costs for possible adjustment.  Lighting controls: Automatic lighting controls are a popular way to save energy by turning off lights when they are not needed or in use. Many different varieties of controls Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-2 are available including ceiling or wall mounted occupancy sensors, built-in occupancy sensors, photocells, daylighting controls, timer controls, and time clocks.  Indoor and outdoor LED channel letter signs: Channel letter signs are large, illuminated signs used for commercial storefronts. These signs emit light through colored, translucent plastic front. Lighting is provided by either fluorescent tubing, neon (single or dual tube) or LED. Even though a wide variety of LED colors are available currently red and yellow dominate the market because they have demonstrated the highest lifetime and reliability.  LED message center signs: LED message center signs are signs able to be programmed to display or scroll information. LED offers monochrome, grayscale, and multi color styles with lower energy demand and consumption than signs using incandescent lamps.  Exit Signs: Exit signs alert people to the nearest emergency egress location and are required in any public, commercial or industrial building. Current technologies include incandescent, fluorescent, cold cathode, electroluminescent, LED, photoluminescent, and tritium. 9.2 LIGHTING MEASURE TECHNOLOGY REVIEW The following resources were reviewed for information regarding lighting measures with findings summarized in Table 9-2. Table 9-2. Lighting Measure Informational Resources Measure CEE DEER Energy Star ITP NW Alliance RTF Web Search >750 W MH, MV, HPS with 8+ T5HO lamps + EB    Bi-level Fixtures  Daylighting Controls     LED Case Lighting   Exit Signs   Retrofits of HID systems to T5 fixtures of 8 or more lamps have been found to be exclusively in high bay or specialty applications. Bi-level switching has shown to be a significant energy saver in areas with little or intermittent use where constant lighting is required. Daylighting is a popular topic and provides several benefits including saving energy and occupant preference over artificial light. On the downside, an improperly calibrated daylight control can lead to less desirable lighting and increased energy costs. Regarding LED case lighting, LED systems are hailed as the next major revolution in lighting technology. 9.3 UTILITY LIGHTING DSM PROGRAM REVIEW The incentive programs of primary utility companies were reviewed for the presence of lighting measures with the findings summarized in Table 9-3. Complete utility programs are referenced in Appendix C and D. Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-3 Table 9-3.

Incentives for daylighting controls include flat incentives per controller installed, per kWh saved rate, and per W connected rate. Some utilities only offer incentives for new construction projects. 9.4 LIGHTING MEASURE CODE REVIEW Table 9-4 provides a brief summary of the code requirements for the evaluated lighting measures in Idaho. Table 9-4. Lighting Measure Code Requirements Measure Code Requirements Notes >750 W MH, MV, HPS with 8+ T5HO lamps + EB IECC 2006 Sec 505 Specifies maximum lighting power densities by building area type. Bi-level Fixtures IECC 2006 Sec 505 Specifies maximum lighting power densities by building area type. Common custom lighting measures: IECC 2006 Sec 505 Specifies maximum lighting power densities by building area type. IECC 2006, adopted by Utah and Idaho, specifies the maximum lighting power densities by building area type. These requirements apply to all new construction projects, alternations or additions or repairs to the existing system, and any alteration that increases the lighting load Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-4 during a change in occupancy or space type. The IECC 2006 code lighting power densities for different building types are summarized in Table 9-5. Table 9-5.

As of January 1, 2009, all luminaries between 150W and 500W manufactured or imported to the United States must meet the ballast efficacy requirements stipulated by EISA in Table 9-6. Table 9-6. Minimum Ballast Efficiency Standards for Metal Halide Luminaries Ballast Type Lamp Wattage Minimum Ballast Efficiency Magnetic Probe Start 150W – 500W 94% Pulse Start 150W – 500W 88% Non-Pulse Start Electronic 150W – 500W 90% Non-Pulse Start Electronic 251W – 500W 92% Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-5 Due to technology limitations, in order to meet the EISA requirements, all metal halide luminaries between 150W and 500 W destined for sale in the United States will essentially be required to contain pulse-start electronic ballasts. The EISA requirements do not limit the availability of replacement parts and bulbs for existing probe-start luminaries so long has manufacturers have existing inventories available. 9.5 LIGHTING MEASURE VENDORS Currently, 9 vendors in Idaho support PacifiCorp’s FinAnswer Express lighting incentive program. A list of these vendors and their contact information is available on the Lighting Energy Efficiency Alliance listings accessed through Rocky Mountain Power’s website. Three of the most active vendors were selected from this list and interviewed regarding the program and the new measures. Additionally, Jim Benya, a lighting system design specialist was contacted for input on daylighting. Table 9-7 contains contact information regarding the lighting vendors surveyed in Idaho for the study. Table 9-7. Idaho Lighting Vendors Vendor Contact Phone Number Arco Electric Tony Passino (208) 552-2185 D&S Electrical Dave Bennett (208) 731-3701 Harris Aircraft, Inc. Ryan Harris (208) 852-2890 Benya Lighting Design Jim Benya (503) 519-9631 As part of this survey, the vendors were questioned regarding current market trends and cost data of these measures. Relevant responses include:  The majority of vendors agreed that daylighting installations are rare due to the high installation cost and difficulty in proper calibration and this could change with an incentive to help offset the initial cost. One vendor quoted a 15 year payback for a recent large daylighting installation (not counting incentives). Jim Benya, an expert in lighting design, added that when installed correctly, daylighting yields favorable energy savings. Important consideration include the amount and size of skylights, window glazing, light color qualities, and designing controls to harvest every available daylight lumen. When done correctly, daylighting is a good investment.  Installation of bi-level fixtures in warehouses and parking garages were common while in halls and stairwells were uncommon. Almost all vendors supplied and installed fixtures with built-in sensors with prices ranging from $125-$150 per fixture.  Two vendors replied that they were familiar with replacing high wattage HID systems with 8 lamp T5 fixtures and most felt it was a good upgrade. However, few manufacturers supply 8 lamp fixtures and most must be special ordered resulting in quoted prices ranging from $300-$500 without installation. Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-6  All vendors agreed that LED was still a developing technology and most viewed it as the future of lighting. Two vendors were familiar with the LED case lighting retrofit while only one sold the product through special order. One vendor expressed that this retrofit was an improvement because fluorescent lights can suffer in colder temperatures while LED lights do not. The price quoted was $30 per foot for the fixture.  Multiple vendors in Idaho expressed a preference for LED exit signs over any other type. All acknowledged that the high cost and permitting requirements for tritium exit signs made them undesirable, except in very select locations where electricity could not be made available. 9.6 EXISTING LIGHTING MEASURE REVIEW Currently, PacifiCorp offers average incentives when compared to similar incentives offered by other utilities. PacifiCorp desires to be in the top echelon of utilities offering incentives and, therefore, must raise incentive levels by 20% on average. Existing PacifiCorp prescriptive measure incentives were reviewed and compared to similar incentives offered by other utilities. Areas of comparison included maximum, minimum, and average incentives, incentive paid per kWh, the percentage of cost paid by incentive, and simple payback period. When considering increasing incentive levels, more emphasis was given to measures that had the most attractive energy savings. The incentive levels for measures with little energy savings were not raised and some were reduced. Incentive levels for replacements of 8’ T12 with premium T8s, CFL upgrades, and T5 fluorescent upgrades were kept the same. Also, replacement of HIDs, replacement of exit signs, addition of photocell and time clock lighting controls, and LED signage were kept the same. Two of the HID category incentives for replacements of MH, MV, or HPS with MHPS were reduced. These reductions were incorporated to reduce incentive levels ($/kWh) commensurate with estimated energy savings. All other incentives were increased by approximately 20%. The comparison of replacement measures can by found in Appendix D. The same review was conducted comparing incentives from other utilities offered on new construction projects. Since only a smaller number of utilities (Idaho Power, Nevada Power, Xcel, Alliant and ETO) offer new construction incentives the comparison was more limited. Most incentive levels were kept the same because PacifiCorp already offers incentives about the average. On average there was a 20% increase for the rest of the measures. The new construction measure table can be found in Appendix D. Provisions in EISA 2007 stipulate that ballasts installed in metal halide luminaries with rated wattage of 150 to 500 watts must meet minimum efficiency requirements after January 1, 2009. Accordingly, Nexant recommends revising the eligibility for incentives for pulse-start metal halide fixtures in new construction/major renovation projects so that only fixtures with a rated wattage larger than 500 watts are eligible. Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-7 9.7 LIGHTING MEASURE PRESCRIPTIVE RECOMMENDATIONS Table 9-8 contains a summary of the recommended measures to include in the prescriptive incentive program. In addition, a trade ally network has been assembled to facilitate the distribution of these measures to the customer. Table 9-8.

The minimum requirements for the recommended measures include:  >750 W MH, MV, HPS with 8+ T5HO lamps + EB: New fixture, at least 8 T5 HO lamps controlled by an electronic ballast.  New Construction 8+ T5HO lamps + EB: New fixture, at least 8 T5 HO lamps controlled by an electronic ballast.  Bi-level fixtures: Fixture must contain an integrated occupancy sensor and vary between at least 2 levels of switching when space is occupied/unoccupied. Section 9 Lighting 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 9-8  Daylighting controls: At least one photo sensor per control, continuous dimming or at least 3 levels of intensity, unit must be properly calibrated.  LED case lighting: Replacement with LED light bars, located in a refrigeration case.  Exit signs (photoluminescent, tritium): Meet visibility requirements, Energy Star and UL approved. 9.10 ESTIMATED LIGHTING COSTS, SAVINGS AND RECOMMENDED INCENTIVES During the process of lighting review, efforts were sought to find a single, reliable source on the costs of the lighting measures. While some cost data was found from the sources listed in Table 9-2 and additional data was provided during the vendor surveys, none proved to be a desirable, main source. Reasons for this include  No one source included data for all the prospective measures  Dates were highly variable between data with some being more than a few years old  Cost data was provided in varying metrics including $/area and $/fixture  Costs for installations greatly differed depending on the vendor, size of the order and the type of installation  The sources of cost data were not consistently documented or reported Effort was made to compute as accurately as possible averages and representations from the data that was collected. Data for daylighting controls especially varied between sources due to the many variables involved in its installation. The numbers for daylighting below were calculated from data provided by Quantec in the 2007 Pacificorp Measures Worksheet. Savings estimates from various sources ranged from 2% to 50%. Nexant’s estimate of 10.5% is a conservative estimate that takes into account potential problems with calibration and savings persistence for this measure. Cost data for stepped and continuous dimming was averaged together to find the energy savings percentage. Since each project’s cost was given in a dollar per square foot metric, this was also averaged ($0.55/sq ft). To find the cost per watt, the maximum power densities of buildings where daylighting was most likely to be found were also combined together in an average (1.1 W/sq ft). Dividing the cost with this value yielded a cost per connected watt metric. Also note that the savings calculated for LED case lighting takes into account both the reduced lighting load and refrigeration savings due to reduced heat gain from lighting equipment (reference PG&E LED Refrigerated Case Lighting Workpaper). Table 9-9 below describes the estimated costs and savings associated with implementing each lighting measure. After taking these costs into account with what is currently offered by other utilities, the recommended incentive levels for the new measures can also be found below in Table 9-10.

A brief synopsis of expected developments in energy codes, new lighting technologies and other issues is provided below.  State and Federal Codes: State and federal codes continue to tighten, mandating maximum lighting power densities for different space types and minimum efficacy. The Energy Independence and Security Act (EISA) of 2007 mandates minimum efficacy standards for general service incandescent lamps, modified spectrum general service incandescent lamps, incandescent reflector lamps, fluorescent lamps and metal halide lamps, as indicated in Table 9-11 and Table 9-12. The suite of lighting measures offered through FinAnswer Express will need to be evaluated periodically with respect to code developments to determine if individual lighting measures warrant inclusion in the FinAnswer Express program. Table 9-11. Minimum Efficacy Standards for General Service Incandescent Lamps Rated Lumen Ranges Maximum Rate Wattage Minimum Rate Lifetime (hrs) Federal Effective Date 1490 – 2600 72 1,000 1/1/2012 1050 – 1489 53 1,000 1/1/2013 750 – 1049 43 1,000 1/1/2014 310 – 749 29 1,000 1/1/2014 All 45 lumens/watt 1,000 Final Rule by 1/1/2017 Table 9-12.

In particular, LED lighting systems have already made inroads into certain markets (i.e. traffic lights, refrigerated case lighting) and will continue to find application in other types of lighting systems. Coordination with lighting research initiatives and lighting manufacturers is recommended for evaluating market-ready, high-efficiency lighting technologies proposed for inclusion in FinAnswer Express program. The continued push for higher efficiency lighting in buildings has resulted in more stringent codes at both the state and federal levels. The definition of high-efficiency lighting continues to change as new lighting technologies are developed and deployed into the market place. Consistent collaboration with lighting manufacturers, energy code developers and lighting designers will be necessary to insure that appropriate high-efficiency lighting measures are included in the FinAnswer Express program. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-1 Section 10 Motors & Drives 10.1 MOTORS & DRIVES OVERVIEW The existing measures were examined with incentives and savings adjusted according to the current market. In addition, potential measures were evaluated and can be found in Table 10-1. Table 10-1. Evaluated Motors & Drives Measures Existing FinAnswer Express Motors & Drives Measures Potential New FinAnswer Express Motors & Drives Measures Premium Motors 1 to 200 Hp Green Motor Rewinds ECMs (Electronically Commutated Motors) Escalator Motor Controllers VFDs Premium Efficiency Motors 201 - 500 Hp 10.1.1 MOTORS & DRIVES MEASURE DESCRIPTIONS  Green Motor Rewinds: A used motor is rebuilt in a controlled, specified process where the rebuilt motor is as energy efficient as the existing design of the motor allows. New motors have different energy efficiency requirements than green motor rewinds because they are not limited by the existing design. A leading proponent of green motor rewinds is Green Motors Practices Group™ (http://www.greenmotors.org/).  Escalator Motor Controller: An AC induction motor control device senses the load on the escalator motor(s) and adjusts the voltage and current accordingly. Since an escalator is a constant speed/variable load application, the escalator motor controller operates the escalator system at its peak efficiency at all times, reduces the motor energy consumption, and provides energy savings.  Premium Efficiency Motors 1 - 500 Hp: This measure includes the 1-200 Hp AC induction motors currently in the program and extends the NEMA Premium standard to motors up to 500 Hp.  ECMs: An electronically commutated motor (ECM) is a fractional horsepower direct current (DC) motor used in commercial refrigeration applications such as display cases, walk-in coolers/freezers, refrigerated vending machines, and bottle coolers. In addition, ECMs can be used as small fan motors for packaged terminal units or in terminal air boxes. Generally, ECMs replace shaded pole (SP) motors and offer at least 50% energy savings. Analysis focused on 10-140 W motors used in refrigeration and 1/3 to 1 Hp motors used in HVAC applications because these are the most prevalent use of ECMs,.  VFDs: Variable frequency drives (VFDs) or variable speed drives (VSDs) are electronic controls that regulate motor speed and torque. These controllers reduce motor and pump energy consumption under partial load conditions. Section 10 Motors & Drives 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-2 10.2 MOTORS & DRIVES RESOURCE REVIEW The following core resources were reviewed for information regarding motors & drives measures. The information findings are summarized in Table 10-2. Table 10-2. Available Measure Information Resources Measure Description CEE DEER Energy Star ITP NW Alliance RTF Web Search Green Motor Rewinds    Premium Efficiency Motors 1 - 500 Hp    Escalator Motor Controller  ECMs  VFDs    Green Motor Rewinds: There is considerable potential for efficiency penalties associated with rebuilding used motors. Without the correct process control, estimates on this efficiency penalty range from 1-2%. The focus of green motor rewinds is to formalize the rebuilding process to eliminate these losses.  Premium Efficiency Motors 1 - 500 Hp: CEE Premium-Efficiency Motors Initiative highly recommends using the “NEMA Premium" brand name in the Premium Efficiency Motors 1 - 500 Hp measure. Using the NEMA Premium brand name eliminates market confusion as to what constitutes an energy efficient motor. In addition, there are many NEMA Premium motor manufacturers to choose from. The “NEMA Premium" trademark is shown in Figure 1. Figure 1: The “NEMA Premium" Trademark A significant development since the last market characterization is that the National Electric Manufacturer’s Association (NEMA) adopted a standard for motors in the Premium Efficiency Motors 200 - 500 Hp measure in 2007. The new standard is contained in NEMA MG 1-2006 Revision 1 2007. Signed into law on December 19, 2007, the 2007 Energy Security and Independence Act adopts the new standard and requires that all new 1-500 Hp motors that are manufactured and sold in the United States meet the new standard by December 19, 2010. There are now published efficiency standards for 1-500 Hp motors. With these changes, any 1- 500 Hp motor bearing the “NEMA Premium" trademark will align with national energy efficiency standards and legislation. The Federal Energy Section 10 Motors & Drives 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-3 Management Program (FEMP) has already adopted NEMA MG 1-2006 Revision 1 2007 in their Designated Product List for federal customers. In addition to the new standards for 200 - 500 Hp motors, additional motors in the 1-200 Hp range are now included in the NEMA Premium standard. These new motors are referred to as “General Purpose Electric Motors (Subtype II)” in the standard and act.

Escalator Motor Controllers are a subset of a larger group of equipment called Motor Efficiency Controllers. Both are “variable torque” devices that operate at constant speed and vary the output torque of the motor to match the necessary motor load. According to two studies from Xcel Energy and Nevada Power, energy savings of approximately 30-40% are possible with Escalator Motor Controllers. The following design characteristics apply to Escalator Motor Controllers: • Solid state motor controllers are designed to dynamically optimize the efficiency of a 3-phase electric motor in constant speed, variable load applications. • The motor load is continuously monitored and the controller adjusts voltage and current accordingly, without losing any speed or performance.  ECMs: Since ECMs are currently part of the program, the resource review was an update to the previous report and can be found in Table 10-5.

Measure Category Utility Program Review Measure Description Alliant APS Avista BPA Energy Trust MidAmerican Energy Motor Up Nevada Power PG&E Green Motor Rewinds Premium Efficiency Motors (1 - 500 Hp)       Escalator Motor Controller  ECMs   VFDs   Green Motor Rewinds: A number of utilities are looking at the potential for green motor rewinds including: • Energy Trust • Tacoma Power • Puget Sound Energy • Idaho Power • BPA • Cowlitz PUD • BC Hydro • PacifiCorp The Green Motor Practice Group (GMPG) began implementing the Green Motor Initiative (GMI) on behalf of the Bonneville Power Administration (BPA) beginning September 1, 2008. Incentives are offered through BPA to GMPG members who complete motor rewinds on motors 15 – 5,000 hp for customers located in participating utility’s territories. The GMPG member receives $2.00/hp for a green motor rewind, of which $1.00/hp is passed along as to customer as an incentive at the point of sale. RTF recently finalized a deemed savings and costs spreadsheet for Green Motor Rewinds. GMPG members can be found in all states in PacifiCorp service territory.  Premium Efficiency Motors 1 - 500 Hp: Because there is a standard for energy efficient 200 - 500 Hp motors, prescriptive programs are becoming more popular. The most comprehensive prescriptive program is offered by APS. This program offers an incentive of $1.50/Hp on all 1200, 1800, and 3600 RPM motors meeting the efficiency requirements. This is the simplest prescriptive program in that there is only one efficiency requirement for the entire range of motors. PG&E offers a well documented, comprehensive program. Prescriptive incentives are only offered up to 350 Hp motors in Avista’s prescriptive program. There are two tiers of incentives; the higher tier is for continuous duty motors while the lower tier is for intermittent duty motors. With this structure, a motor operating continuously receives more Section 10 Motors & Drives 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-7 incentives than the same motor operating intermittently. The incentive for continuous duty is twice that for intermittent duty. The average incentive is $5.25/Hp. Comparisons of evaluated programs are shown in Table 10-8, Table 10-9, Table 10-10, and Table 10-11.  Escalator Motor Controller: Presently, only Nevada Power offers incentives for Escalator Motor Controllers. This program pre-qualifies manufacturers and offers $20/Hp controlled. Most escalators have 20 Hp motors, resulting in a typical incentive of $400 per motor controller.  ECMs: The utility review and cost and savings are shown in Table 10-5 and Table 10-7, respectively.

CW Silver Industrial Services, Inc. and Western Industrial Motor & Machine, Inc. indicated that they are already rewinding to green motor rewind standards and are not charging extra for it because they cannot cost effectively maintain two different processes. They indicated that a controlled rebuild process is the only effective way to produce quality, warranty guaranteed motors and that green motor rewinds make good business sense. Unfortunately, many of these quality shops get limited rewind business because shops that are providing inferior rewinds charge less. Consequently, to be competitive the vendors must receive incentives. Section 10 Motors & Drives 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-12 In talking with the Green Motors Practices Group™ and green motor rewinds vendors the following implementation process was identified. EEA Participant Process • The EEA Participant seeks and obtains membership with the Green Motors Practices Group™ • The EEA Participant notifies the Motor & Drives EEA Participant Coordinator that they have become members of the Green Motors Practices Group™ and requests to join the green motor rewind program by completing an EEA application and signing the EEA agreement. • The Motor & Drives EEA Participant Coordinator verifies the EEA Participant’s membership with the Green Motors Practices Group™, reviews other information on the EEA application, approves the EEA agreement, and lists the EEA Participant in the green motor rewind program. Incentive Process • The Green Motor Participant rebuilds a customer’s motor in accordance with the process established by the Green Motors Practices Group™. • The green motor rewind participant reports the rebuild to the Green Motors Practices Group™ who records it in their database and reports the rebuild to the Motor & Drives EEA Participant Coordinator on a monthly basis. • The green motor rewind participant submits an application for incentives on motors they have rebuilt monthly. • The Motor & Drives EEA Participant Coordinator receives, verifies, and pays qualifying incentives to the EEA Participant. EEA Participants can elect to pass along a portion of the incentive to the customer ($1.00/hp is practice in BPA territory and part of the Green Motor Initiative)  Premium Efficiency Motors 1 - 500 Hp: CW Silver Industrial Services, Inc. and Dykman Electrical, Inc. are top vendors in the current 1-200 Hp premium motor program and find the extension of prescriptive incentives to the 201-500 Hp size a natural extension of their business. However, they believe that there will be minimal additional sales because most business in this size range is rewinds. With EPACT motors still available, there is a need for premium motor incentives because currently premium motor sales are only 40% of the market. In order to increase market penetration of premium motors, Dykman recommends that Rocky Mountain Power encourage their CCMs to educate customers on the benefits of premium motors and offer regional training seminars for customers. Intermountain Fuse markets 1-5 Hp motors. Most motors in this size range are premium efficiency and, therefore, there is little choice in motor efficiency. Intermountain Fuse would Section 10 Motors & Drives 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-13 like to see more economic development effort from Rocky Mountain Power so that more companies using motors are brought into Utah. Also, they would like to see more work done with the OEMs on the benefits of premium motors.  Escalator Motor Controllers: Many of the escalator motor controller vendors expressed interest in helping bring this emerging technology to the market. Potential markets include airports and shopping malls where the escalator operating hours are long and loads are variable. Many are willing to stock the units because emergency escalator breakdowns are common and this is the most advantageous time for installations.  ECMs: Refrigeration Supplies Distributor is finding the ECM market difficult to penetrate. Primarily, this is due to “hidden labor charges” involved in unloading and re-loading refrigerator cases to remove and replace the motors. When these costs are included in the retrofit costs, the incentives that are currently available are not enough to motivate customers to retrofit their cases. Refrigeration Supplies Distributors questions the quality and life of some of the ECMs they have demonstrated for their customers and is actively looking for better ECMs.  VFDs: CW Silver Industrial Services, Inc. reports that they are having difficulty penetrating the retrofit market where the program incentives are most significant. However, they feel that this is no fault of the program but is a matter of pursing the retrofit business more aggressively. In general, they find the incentives for VFDs very attractive and think they will eventually become successful. 10.6 MOTORS & DRIVES PRESCRIPTIVE RECOMMENDATIONS Table 10-14 contains a summary of the recommended measures to include in the prescriptive incentive program. In addition to including these measures, a trade ally network has been assembled to facilitate the distribution of these measures to the customer. Where available, the exiting motor ally networks will be utilized. Table 10-14.

Incentives were determined by looking at the incremental cost percentage ratio in the current 1-200 Hp premium motor program and using similar ratios for the green motor rewind incentives. This resulted in an incentive of $2 per Hp for green motor rewinds. On average, 52% of the green motor rewinds incremental cost will be covered by the proposed $2.00/hp incentive. This is a reasonable cost share and should be significant enough to encourage motor shops to accommodate green motor rewinds.

Determination of incentives was influenced by the near-term phase out of incentives in response to the 2007 Energy Security and Independence Act. No changes were made in the incentives offered for 1-200 Hp motors. For 201-500 Hp motors, the incentive was based on a smooth transition from the 200 Hp size, the current incremental costs, and the incentives being offered by other utilities. The recommended incentives for 201-500 Hp motors are estimated to cover 39% of the incremental costs on average. The retrofit market for 201-500 Hp motor is entirely rewinds as seen in Table 10-21. Therefore, these incentives will be limited to new construction projects and purchases of spare motors.  Escalator Motor Controller: Since escalator motor controllers are relatively new, little data for comparison is available. However, Nexant was able to evaluate the savings estimates and incremental cost based on two studies, one by Nexant for Xcel Energy and another by Nevada Power. Currently, Nevada Power runs the only prescriptive program offering a $20 per Hp incentive. Nexant’s analysis indicates that this would be too low to achieve market penetration under PacifiCorp’s rate structure. Therefore, an incentive of $38 per Hp is recommended. There are no changes are recommended for ECM or VFD incentives at this time.

This is particularly true in the 201-500 Hp motor sizes as shown in Table 10-21. Determining if and when customers will rewind their motors depends on factors including how cost effective and timely it is to get a new motor. However, a growing trend is that customers are stocking spare motors to install during breakdowns. The time required to rebuild the broken down motor is no longer a driving factor and, therefore, motors are being rebuilt. Green motor rewinds will give access to these rewind savings that are becoming more popular in today’s market. Table 10-21. Motor Rewind Trends1 Motor Size (Hp) % Rewind 1 to 5 20% 6 to 20 61% 21 to 50 81% 51 to 100 90% 101 to 200 91% 201 to 500 100% 1 Pacific Gas & Electric Company. 2006 Work papers. 2006 Motors unit savings V14.xls. Bonneville Power Adminstration recently unveiled the Green Motor Initiative, providing prescriptive incentives for Green Motor Rewinds. PacifiCorp should tie in with the Green Motor Initiative and mirror program style, incentives and qualified motor rewind shops for consistency across the Pacific Northwest.  Premium Efficiency Motors 1 - 500 Hp: Premium efficiency 200 - 500 Hp motors are a natural extension of the current program and have excellent potential now that efficiency standards have been established. While there is only two years before the new code requirements, incentives should be provided for premium efficiency motors because nearly 40% of the market is still buying available EPACT motors. Since the lifetime of Section 10 Motors & Drives 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 10-19 these EPACT motors is 15 years, offering incentives will get long-term savings now. From market feedback, the net to gross ratio for the entire Motors and Drives section is approximately 80%. The recommended measure information is shown in Table 10-20. These incentives should be phased out around December 2010.  Escalator Motor Controller: Escalator Motor Controllers is an emerging technology that appears to have promise for prescriptive incentives.  ECM: ECMs have only been in the program for a year and increased savings is expected as the technology becomes more familiar to customers and EEA Participants. One of the most significant barriers with the refrigeration retrofit market for ECMs is the hidden labor costs associated with loading and re-loading the refrigerated cases while removing and replacing the motors. From a utility standpoint, this barrier is difficult to overcome because the program incentives are not able to incorporate such hidden labor costs. The best approach is to focus on having new equipment specified with ECMs and having vendors stock ECMs. Therefore, they are readily available to install in emergency breakdowns of existing refrigerated cases.  VFD: VFDs have only been in the program for a year and already they have begun to catch on in the market. While the new construction market is limited due to energy code, the retrofit market is just beginning to be tapped and there should be good growth at the recommended incentive levels. 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 11-1 Section 11 Office Equipment 11.1 OFFICE EQUIPMENT OVERVIEW According to the Department of Energy’s Building Technology Program, “Office equipment is the fastest-growing use of electricity in commercial buildings in the United States, accounting for 7% of all commercial-sector power consumption” (www.eere.energy.gov/buildings/). In light of the load growth in this sector, an expanded set of high-efficiency office equipment based on ENERGY STAR office products was evaluated. These measures are in addition to the existing plug load occupancy sensor measure. Table 11-1 summarizes the evaluated office equipment measures. Table 11-1. Evaluated Office Equipment Measures Existing FinAnswer Express Office Equipment Measures Potential New FinAnswer Express Office Equipment Measures Plug Load Occupancy Sensors Computers (including Notebooks and Tablet PCs) Copiers and Fax Machines Digital Duplicators External Power Adapters Mailing Machines Monitors Printers, Scanners, and All-in-Ones Water Coolers Network PC Power Management Software Single Outlet Server Power Supplies 11.1.1 Office Equipment Measure Definitions Detailed descriptions of the office equipment measures identified in Table 11-1 as well as ENERGY STAR requirements, were applicable, are listed below:  Plug Load Occupancy Sensors: Plug load occupancy sensors control low wattage devices using an occupancy sensor. Common applications are computer monitors, desk lamps, printers, and other desktop equipment. Under the current FinAnswer Express program, only equipment with passive infrared (line-of-sight technology that senses changes in the heat emitted by occupants) and/or ultrasonic (senses occupants by the changes in ultrasonic waves that it transmits and receives) detectors controlling electric plug loads are eligible.  Computers: Computers account for significant energy use in a typical office. A large portion of this energy use can be attributed to leaving computers on overnight and inefficient power supplies. An ENERGY STAR computer has a power supply that is at least 80% efficient and has a power factor >0.90. In addition to the power supply requirements, ENERGY STAR requires computers enter a stand-by mode that Section 11 Office Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 11-2 consumes <2W compared to >50W when the computer is in use.  Copiers and Fax Machines: Copy machines make duplicates of original hard-copy documents. ENERGY STAR copiers and fax machines are rated based on total energy consumption per week as a function of output speed and are equipped with a low power “sleep-mode”. ENERGY STAR models consume approximately 25% less electricity than traditional models and include a power-down function when not in use.  Digital Duplicators: A digital duplicator employs the ink-on-paper process to copy documents. A "master" copy of a document is wrapped around a print cylinder, ink squeezes through the cylinder into tiny holes in the master, and onto a sheet of paper. ENERGY STAR models consume approximately 25% less electricity than traditional models.  External Power Adapters: External power adapters convert alternating line current to direct current to be used by devices such as cell phones and notebook computers. They consume over 300 billion kWh/yr and account for 11% of the nation’s electrical use. ENERGY STAR models require a higher efficiency than standard models based on the size of the adapter. ENERGY STAR models are required to consume <0.75W when in a no-load status. Overall, ENERGY STAR adapters use approximately 30% less energy than traditional models.  Mailing Machines: Mailing machines save time and money by automatically postmarking correspondence. ENERGY STAR mailing machines are rated based on total energy consumption per week as a function of output speed and are equipped with a low power “sleep- mode”. ENERGY STAR models are approximately 25% more efficient than traditional models.  Monitors: Monitors are used to view the output from computers. One common misconception is that screen savers reduce energy use, when in fact they may actually increase the energy consumed by a monitor. ENERGY STAR requires that monitors use <2W while in sleep mode and <1W while in standby mode. ENERGY STAR units use between 25 and 60% less energy than traditional units.  Printers, Scanners and All-in-Ones: Printers, scanners and all-in-ones take a digital input and create a hard-copy or visa versa. ENERGY STAR requires that printers have double sided print capability, thus, saving paper. ENERGY STAR models can use up to 25% less energy and cost the same as traditional units.  Water Coolers: Standard water coolers can use the same amount of energy in a year as a typical refrigerator. Nationwide, water coolers consume four billion kWh per year. By utilizing better insulation, separating hot and cold, and using better cooling mechanisms, ENERGY STAR water coolers use up to 50% less energy than traditional models. Section 11 Office Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 11-3  Network Power Management Software: Network power management software reduces energy use by remotely placing computers and monitors in a low power sleep mode after a predefined period of inactivity. While most computers already include this individual functionality, it is typically not enabled or used by individual users. When computers are connected to a network, the network power management software automatically controls the power settings of networked personal computers at the server level.  Single Outlet Server Power Supplies: These power supplies take A/C line voltage and change it to D/C for use by solid state computer electronics. New ENERGY STAR computer requirements and the 80-Plus initiative require an efficiency of >80% at 20%, 50%, and 100% of nameplate loading and a power factor > 90%. 11.2 OFFICE EQUIPMENT MEASURE TECHNOLOGY REVIEW Table 11-2 identifies the key informational resources utilized to conduct the office equipment measure technology review.

ENERGY STAR currently rates the evaluated measures and provided cost and savings data. ENERGY STAR updated the specification for computers in November 2008 and external power supplies in July 2008. Revised specifications for imaging equipment and monitors are currently under development. These revisions focus on increasing performance efficiency requirements both during active equipment use and stand-by mode. Updated imaging equipment and monitor Section 11 Office Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 11-4 specifications are expected in April 2009. ENERGY STAR is also drafting a new specification for high-efficiency enterprise servers, with a final specification expected in February 2009. In June of 2007, CEE began a consumer electronics initiative. While focused on the residential market sector, initial market data compiled overlaps with some evaluated measures. Additional cost and savings information for the single outlet power supply measure was obtained from the 80-Plus program managed by ECOS Consulting. This program is an industry initiative to increase the efficiency of desktop computer and server power supplies. It sets a minimum efficiency requirement of 80% under 20%, 50%, and 100% of nameplate loading for internal power supplies and >90% power factor requirement. The 80-Plus program began with the development of a testing protocol to demonstrate compliance with the program eligibility requirements. NEEA became the first sponsor of the program in 2004 and the program has continued to gather utility and industry support. In July 2007, the 80-Plus requirements were incorporated into the revised ENERGY STAR computer specification. The program continues to incorporate efficiency power supplies into desktop computers and servers and is now targeting data center and enterprise computer servers. Detailed cost and savings data obtained from the sources identified in Table 11-2 are provided in Appendix B. 11.3 UTILITY OFFICE EQUIPMENT DSM PROGRAM REVIEW Table 11-3 identifies which of the evaluated utilities currently offer non-residential customers a prescriptive incentive for the evaluated office equipment measures.

With the exception of Idaho Power, there is a lack of prescriptive incentives offered for ENERGY STAR office equipment. PG&E’s incentive program is an up-stream effort for high-efficiency monitors that exceed the ENERGY STAR requirements by 25% or more. A preliminary search identified only one other Investor Owned Utility (IOU) offering an incentive for ENERGY STAR office equipment. Southern California Edison (SCE) offers a $100 incentive for ENERGY STAR copiers. A common approach is the promotion of ENERGY STAR office equipment through customer educational brochures, web sites, and energy savings tips. Utilities utilizing this approach include APS, Avista, PSE, NYSERDA, and BC Hydro. Idaho Power was the only utility offering a customer incentive for purchase of high-efficiency single outlet server power supplies. The other utilities promoting this effort where working with the 80-Plus program through upstream market delivery channels. Several utilities offer incentives for network power management software applications. Idaho Power and PG&E provide incentives for plug load occupancy sensors similar to the current FinAnswer Express program. In addition, Eugene Water and Electric Board and SCE offer incentives for plug load occupancy sensors. A detailed summary of the utility incentives and qualification requirements corresponding with information contained in Table 11-3 is presented in Appendix C. Section 11 Office Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 11-6 11.4 OFFICE EQUIPMENT MEASURE CODE REVIEW Applicable code requirements were only identified for external power adaptors. The Washington and California state appliance standards address minimum efficiency requirements for external power adaptors with both having the same requirements. As part of the 2007 Energy Independence and Security Act signed into law on December 19, 2007, a new federal minimum efficiency standard for external power adaptors becomes effective for units manufactured on or after July 1, 2008 and will supersede the Washington and California requirements. This act requires DOE to complete a rulemaking for revised standards for external power adaptors by July 2011. The requirements for external power adaptors are summarized in Table 11-4. Table 11-4.

Some key feedback received included:  Several Staples representatives from different states remarked that many products offered are ENERGY STAR rated. However, most consumers are unaware of the rating and don’t ask for it.  Many independent office equipment dealers offering mostly imaging equipment stated that all of their products are ENERGY STAR rated and that this was due to manufacturer initiatives rather than consumer demand.  There were many vendors that had never heard of ENERGY STAR nor recalled any customers asking about it.  Some water cooler vendors remarked that reliability was their primary concern and that they were hesitant to switch to something that they didn’t know or trust. Other water cooler vendors remarked that they had switched to ENERGY STAR rated equipment because that was all that their manufacturers sent them anymore. A water cooler vendor that had not yet switched was aware of ENERGY STAR water coolers and was in the process of evaluating whether or not they were economically justified. This vendor mentioned that an incentive would surely affect his decision to buy ENERGY STAR. Section 11 Office Equipment 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho 11-8 The vendor survey instrument and additional vendor responses are provided in Appendix A. 11.6 OFFICE EQUIPMENT MEASURE PRESCRIPTIVE RECOMMENDATIONS For the existing office equipment measure, plug load occupancy sensors, Nexant recommends expanding the description of eligible equipment to include plug strips which limit stand-by power consumption of plug-load appliances by completely switching off power to the strip when a minimum electrical load is sensed, or by using a timer. The new measure category should be renamed “Smart Plug Strips” and use the provisional deemed savings and costs identified by RTF. Of the potential prescriptive office equipment measures, only one, network power management software, is recommended for post-purchase prescriptive incentive delivery under the FinAnswer Express program. Post-purchase prescriptive incentives are not recommended for the suite of ENERGY STAR office products at this time because:  The limited presence of prescriptive incentives from other utilities for these measures.  Market reports from CEE and ENERGY STAR that show significant market penetration of these measures  Procurement regulations and guidelines that require all federal facilities, and many state government, schools, and large corporations to specify ENERGY STAR or better equipment.  Little to no customer incremental costs associated with purchasing ENERGY STAR qualified office products. Incorporation of prescriptive incentives for single outlet power supplies is not recommended at this time for the FinAnswer Express program for the following reasons:  The 80-Plus performance requirements were incorporated into the recently upgraded ENERGY STAR computer specifications, and as such, their market penetration is expected to increase significantly for the same reasons as noted above.  Only one other utility, Idaho Power, offers a direct customer incentive for this measure. Should PacifiCorp choose to pursue this measure more aggressively, participating in the existing 80-Plus program with its established upstream marketing and promotional channels will likely provide a more cost-effective means to realize savings from this technology. To maintain consistency in the marketplace, recommended eligibility requirements and incentives for network PC power management software are based on similar utility incentive programs. Estimated savings and cost data are taken from a number of reports done by Quantec LLC. Table 11-8 contains a summary of the office equipment measure prescriptive recommendations. Additional information on the recommended baseline, measure eligibility requirements, cost, savings and incentives for this measure are provided in the balance of this section.

Continued customer awareness training and outreach is expected to be the best approach for these measures. Incentives for network PC power management software should continue to be viable unless future ENERGY STAR computer specifications disallow user overrides of power management functions. This change appears unlikely in the near future. . 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-1 Appendix A General Vendor Survey Results A.1 APPLIANCE MEASURE VENDOR SURVEY RESULTS Table A-1 Summary of Appliance Measure Vendors Vendor Phone Number State 1 Home Depot (208) 542-2520 ID 2 Lowes (208) 542-9030 ID 3 Northgate Appliance (208) 524-2122 ID Number indicates a “yes” No number indicates a “no” or no response 1.

Number indicates a “yes” No number indicates a “no” or no response 1. Do you sell/install any of the following measures? Attic Insulation (1) (2) Only rarely with special order Wall Insulation (1) (2) Only rarely with special order High-efficiency Windows (1), (2) (3) Primarily whole window products from Marvin Windows and Amsco Windows Reflective Window Films Cool Roof Products (1) No, is not a roofing company 2. What percentage of your work is divided between commercial and residential? (1) 50% Commercial (mostly small commercial), 50% Residential (2) 2% Commercial, 98% Residential. Of residential customers about 60% is new construction, 40% is retrofit. (3) 60% Commercial, 40% Residential 3. Can you estimate what percentage of work is performed on commercial new construction or retrofit projects? (1) 25% New construction, almost all new construction, very little retrofit work (of commercial customers) 75% Retrofit, primarily residential, very little commercial. (2) 60% New construction, 40% retrofit 4. How would you categorize the nature of the customers’ purchase of energy efficient products? Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-4 (2) Generally in the residential market, 90% of purchased windows are standard code-compliant windows that builders install in spec homes. Only on custom homes (about 10% of market) are EnergyStar windows common. 5. What percentage of commercial customers request/install elevated levels of attic or wall insulation? Do you attempt to sell additional attic/wall insulation? (1) 0% New construction, 0% Retrofit. Projects usually meet the specifications supplied by general contractor. Very little opportunity to up-sell additional insulation unless working directly with customer. Sometimes in small commercial spaces for new construction the insulation levels are increased from R-38 to R-49. 6. What percentage of commercial customers request/install high-efficiency windows (i.e. EnergyStar)? (1) Very few new construction projects. Retrofit is more common, but generally only code- compliant windows (double-pane, low-e). Very little commercial work is done. Best opportunity to sell windows is on existing residential homes replacing older windows. On new construction projects, the incentive to cut costs prevents many customers from installing high-efficiency windows. (3) The EnergyStar specification is confusing in ID, so a low-e double glazed product is recommended, but doesn’t always comply with EnergyStar. In ID climate, breather tubes are required, which hurts the thermal performance of the window. Best achievable U-factor with breather tubes is 0.33. 7. How many cool roofs have you installed for commercial customers in the last year? (1) None, only do gables and roof vents. 8. How many commercial customers have you installed window films for in the last year? (1) None 9. What is the average cost to install attic/roof insulation per square foot in commercial buildings? (1) Blown-in fiber glass in attic costs $0.68/sf for R-38 and $0.85/sf for R-49. Cellulose costs a bit more. 10. What is the average cost to install wall insulation per square foot in commercial buildings? (1) Don’t generally apply ci insulation to existing buildings. Drill and fill is rare as the mesh netting/screen in wall cavities prevents additional insulation from being added. 11. What is the average cost to install EnergyStar windows per square foot/per window? How does the price of EnergyStar windows compare to standard code-compliant windows? (1) Unknown (3) Provided material cost info for standard 3’ x 4’ casement window (most popular) Clear on Clear – air-filled - $430.00 Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-5 Low-e 272 with clear interior lite – air-filled - $460.00 (U-factor = 0.35, SHGC = 0.29) High-R triple pane with low-e (<15 sq. ft.) - $660.00 (Very uncommon) In ID where breather tubes are required, cannot do argon gas fill. 12. Would an incentive provided to Customers from <Rocky Mountain Power (UT and ID), Pacific Power (WA and CA)> encourage more customers to install additional insulation, high- efficiency windows, window films? (1) Probably (2) Helps a bit. Used to participate in Home Energy Savings program as a contractor. (3) Likely. The cost differential isn’t so large that it inhibits customers from going with a higher efficiency window, but incentives encourage the fair number of customers who install code-compliant windows to go with higher-efficiency. 13. What one or two key items could <Rocky Mountain Power (UT and ID), Pacific Power (WA and CA)> do to help increase the percentage of the measures installed by customers today? (1) Incentives would help. (2) Incentive should encourage proper installation of windows. Suggest they should be wrapped and siliconed, not just taped. (3) 1. Don’t use the EnergyStar specification – it isn’t optimized for ID and just causes confusion. Instead, specify U-factor and SHGC and require the NFRC certification. 2. Make the Rocky Mountain Power website clearer – it is incredibly confusing, especially when trying to distinguish between Idaho and Utah program differences. 14.

How would you categorize the nature of the customers’ purchase of energy efficient products? For example, are they for emergency repair? Retrofit or remodeling? New construction? (4) Mainly retrofit and new construction, for an emergency repair it is more important to get equipment online as soon as possible than it is to upgrade efficiency (5) New construction projects are 100% energy efficient, retrofits are 50/50 energy efficient 4. How many of these measures do you have available in your daily inventory? (4) Most (5) Full line, backup parts for everything 5.

Representatives for many food service equipment manufacturers. Serve areas in Southern Idaho, Western Wyoming, Eastern Oregon. Satellite Store in Spokane, WA cover the northern portions of Idaho and Eastern Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-9 Washington. Have worked with Avista and Energy Trust of Oregon on Food Service Incentives. (2) Carry all of the above products, but not aware if any are EnergyStar. Only thing with EnergyStar sticker on show floor is Solid-Door refrigerators. (3) Yes – major retailer of food service equipment in Intermountain West. 2. Are there any other high-efficiency measures that you’re familiar with? (1) Not energy-specific, but also focus on clean air, and water conservation aspects of food service equipment. (3) Customers are becoming much more interested in high efficiency ice-machines, primarily because major manufacturers have stopped selling ones that don’t comply with CA energy code and/or EnergyStar. 3. How would you categorize the nature of the customers’ purchase of energy efficient products? For example, are they for emergency repair? Retrofit or remodeling? New construction? (1) Most equipment is replaced at end of life or upon failure. Very few customers upgrade before equipment fails. Incentive would be required to encourage before-end-of-life replacement. Most equipment replaced on failure. Not much of a price up-charge for some EnergyStar Equipment. Pretty seamless transition for customers into the EnergyStar equipment. No lines are exclusively EnergyStar equipment – some are 90%energy star. (2) Usually end-of-life replacement or for a new building. Customers interested only in first cost, not energy savings. Customers are not requesting EnergyStar. (3) Equipment generally lasts 5-7 years – Customers start shopping for replacements around year 5, but aren’t generally interested in upgrading before that time. 2 reasons to replace equipment: 1. Failure (Major failures generally occur when weather is hot – 2nd week of June is extremely busy month) 2. Features – Chefs preference plays a big role in purchasing decisions, also any features which make equipment safer, increase longevity, or easier to use generally compel users to buy before their equipment breaks. Energy-efficiency is becoming a larger concern for customers. For example, special filters in fryers that allow oil to be used longer and kept clean are a big draw for commercial fryers. 4. How many of these measures do you have available in your daily inventory? (1) Refrigeration is in stock. Other cooking equipment is custom order. (2) None on show floor, except EnergyStar solid-door refrigerators. (3) All products with EnergyStar logos are stocked in warehouse – many displayed on showroom floor with EnergyStar stickers. Sales across all states (CO, NM, AZ, NV, ID) were about 300-400 combi ovens last year, 100-150 convection ovens, and over $6 million in refrigerators. Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-10 5. For those that aren’t stocked, do you have any feel for the availability and lead times to obtain them? (1) Generally 2-3 weeks. (2) Couple of weeks. 6. What percentage of your customers do you see installing these measures? (1) 40%-50%. Really try to push EnergyStar products. Some products sold are primarily EnergyStar (i.e. refrigerators) and are relatively cost-effective to upgrade. Other equipment is more difficult to get customers to upgrade to EnergyStar – an incentive would help. (2) None. Customers are only interested in first cost. (3) Not sure – for new construction projects, EnergyStar is definitely encouraged over other products, but for retrofit, generally defer to customers judgment. 7. Can you estimate the average percentage incremental cost and customer payback for these higher-efficiency measures? (1) Minimal upgrade cost for refrigerators. No feel for upgrade cost for cooking equipment, other than that is fairly significant, particularly fryers. (2) Not very familiar with equipment. (3) $100 more per unit or 10-20% on average for a high-efficiency unit. 8. What one or two key items could <Rocky Mountain Power (UT and ID), Pacific Power (WA and CA)> do to help increase the percentage of the measures installed by customers today? (1) Work with State and Industry organizations that serve restaurants and food service equipment manufacturers to inform them of incentives. Talk to General Manager for more information. (2) Had to serve customer. (3) Seasonal promotions are a big draw to customers when shopping around for equipment. Incentives. 9.

Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-11 A.6 HVAC MEASURE VENDOR SURVEY RESULTS Table A-6 Summary of HVAC Measure Vendors Vendor Phone Number State 1 Brower Mechanical (916) 624-0808 CA 2 R and R Heating (509) 484-1405 WA 3 Sound Geothermal Corporation (801) 244-8800 UT 4 Quantum Engineering (208) 523-8068 ID 5 Proliphix (978) 692-3375 MA 6 RSD Total Control (509) 838-0593 WA 7 ThermoPros (916) 933-0443 CA 8 TCS Basys (801) 487-7741 UT Vendors 1-4 were contacted in regards to geothermal heat pumps. The remainder was contacted about portable classroom controls. The survey tool used for HVAC measures differed from the standard survey tool. Summaries of the conversations with these vendors can be found below. Geothermal Heat Pump Vendors: Product Offered (1) Geothermal heat pumps to residential and commercial customers. Mostly prefers water- to-water heat pumps as they can be tied into the HW/CHW system and are good for radiant heating, which is common in the bay area and many parts of CA. Vendor installs only closed-loop systems so as not to have to deal with legal issues surrounding water rights, EPA, etc. Typical lifetime of system is 20-25 years. (2) Vendor is a geothermal heat pump contractor – mostly for residential customers. Vendor installs the slinky style ground loop most commonly. (3) Designer for geothermal heat pump systems for commercial customers. Mentioned ASHRAE Typical lifetime of system is 20-25 years. Schools can be major beneficiaries of GSHP, as well as hotels, extended care facilities, apartment buildings, office buildings  just about any commercial building. (4) Designer for geothermal heat pump systems for commercial customers. Costs (1) Costs are highly variable depending on the type project. Largest upfront cost is the cost to drill the well for the ground-loop. Costs average about $10/ft and it takes approximately 250 drilled feet per ton of cooling. A typical house with 3-4 tons of cooling would face drilling costs of $7500-$10,000. Commercial applications much more expensive – must drill 10s to 100’s of vertical wells for the ground loop. Any building with a constant 24/7 load is a “no-brainer” for geothermal heat pump installation. (2) Cost is highly variable depending on the type of project. Costs average about $7/ft for vertical bore drilling in WA. Costs depend on type of soil and can be as low as $3/ft in Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-12 Florida. Can’t understand why schools don’t install geothermal heat pumps as it is a good payback for them. (3) More expensive than conventional systems up to about 300-400 tons, then geothermal can be cheaper because of reduced mechanical room costs, maintenance, etc. Definitely more expensive then conventional ASHP for smaller systems. Largest cost component of the system is installation of the ground loop. Costs quoted for Utah are $9.75-11/vt ft. and 185-200 vertical feet are required per ton of cooling = $1800 to $2200 per ton of cooling. Costs will be highly dependent on soil conductivity, water content, soil type, etc. Operating costs are about half of conventional chilled water system at about $0.125/yr/sq. ft. Usually a ground source heat pump (single stage) is about $250 more than a water-source heat pump. A single stage GSHP is about $1000 more than a water source heat pump (per unit) (4) Major cost is the ground-loop system. Closed-loop is most expensive option. Open-loop (pump and dump) systems cheaper, especially if existing well or well must be drilled anyway. Paybacks range from 2-10 years. Vertical bore hole closed ground loop systems can be as high as $12/ft, and use 200ft/ton. Incentive Program Results (1) SMUD attempted a program some time back and tried to defray the upfront drilling costs with some success. Goal was to reduce peak kW consumption of cooling/heating systems in commercial buildings. Sierra Power had a very successful program. Doesn’t remember any details, but should look into it. Best place to target incentive is on the drilling costs. If costs can be reduced from $10/ft to $7-8/ft, that will lower costs of the whole system by up to $500-1,000 per installed ton. Other key is to make sure qualified personnel are designing/installing/servicing these systems. If not a qualified contractor, huge problems can occur. Suggest involving IGHSA or other type of certification agency. (2) Residential and commercial incentive programs are available but rarely advertised – usually it is a “custom” project where contractor, customer and utility work together from the beginning. No prescriptive programs he is aware of. (3) Utah offers up to a $50,000 tax incentive for renewable energy systems (including GSHP) as of the last legislative session. See R-638-2 in the tax code or Utah Code sections 59-7-614, 59-10-1014, and 59-10-1106 or Utah Senate Bill 223. Goal for utilities is to have general energy reduction, peak shifting and or load leveling. GSHP have significant load leveling characteristics since they operate at peak efficiency with constant ground temp rather than part-load efficiency with changing air temp. General energy reduction occurs in the summer, but is partly offset by electric energy use in the winter. Vendor suggests that multi-stage systems be incentivized differently than single-stage systems. Moon Lake Electric has a ground-source heat pump program. Nevada Power offers incentives for GSHP only at the custom level and requires energy modeling. Also Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-13 suggests incentivizing types of systems differently. 80% of systems installed are hybrid systems (smaller ground loop and includes a cooling tower) which can control the entering water temperature more precisely and boost efficiency of heat pumps. Vendor also suggested that minimum efficiency criteria be set for these systems. Problem with fixed incentive per ton of cooling in the past was that installers used it as excuse to raise costs. However, commercial marketplace has changed significantly in the past few years and competition is fierce, so that is unlikely to happen. For any system, the ground loop is typically contracted out separately from the design/heat pump installation, so there is less of a chance that the end customer will be overcharged. (4) BPA incentives are available for residential systems - $3,000/system for PTCS certified systems. BPA apparently also provides incentives for commercial customers - $0.13/kWh for existing buildings and $0.20/kWh for new buildings. Federal tax deduction - $300/system ID – low-interest loans (4%) for com/res heat pump systems UT - $50,000 tax deduction for qualifying heat pump systems (up to 10% of system cost) Federal Builders Tax Credit – up to $1.80/sf Marketing Approach (1) Mostly work with large homes in California that can afford system. Geothermal system has multiple benefits – lower variability of monthly conditioning bills, longer-life equipment, etc. Commercial buildings should be targeted during the new construction phase because excavation costs are significantly lower if you can piggyback on existing foundation, pipes, and drainage excavations. (2) Vendor noted that it is difficult to install geothermal heat pump systems because of a lack of design expertise. No one is really that experienced with designing them and it results in contractors/engineers with conflicting opinions, which only hurts the customer. (3) Discussed the Trade Ally approach to marketing. Felt that the incentives program would benefit greatly from a coordinated approach where installers/designers work with utility to “sell” geothermal heat pumps to commercial customers. (4) Focused on commercial buildings and high-end residential. Annual projects are 20-30 per year, about 70% commercial/30% residential. Lots of schools are getting GSHP systems. Savings and Payback (1) One project done in Nevada had $1,000,000 investment to drill 300 wells. Constantly loaded – simple payback was around 4 years. Best commercial products are those with constant cooling/heating loads such as spas/pools, ice rinks, year-round schools, 24/7 buildings (i.e. casinos). Water-to-Water options open up possibilities of process cooling in industrial settings (but not that common). Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-14 (3), (4) Did not discuss in depth. Suggested that there are a number of case studies that provide this information and underscored how variable the costs are based on individual project circumstances. Other Sources and Info (1) Geooutlook, Climatemaster.com, Waterfurnace (2) See additional questions below. (3) GSHP systems typically are only sized up to 35 tons, some up to 50 tons. (4) Open-loop systems require state permitting generally. The permitting is usually easy to get for open-loop systems since water isn’t actually consumed. Re-injection permits are required in WY and ID. No federal or EPA oversight. Usually deal directly with the State department of water resources. GSHP systems are generally the same devices as water-source heat pumps, but are rated at different standards than WSHP. Generally a water-well driller used for open-loop system installation and a common mechanical contractor installs the heat pumps system in the building. Common configuration is to size ground-loop for heating and install a cooling tower in the loop to take care of peak cooling days. Vendor (2) offered to provide more information about geothermal heat pumps in response to e- mail questions. The following questions were sent for response and the vendor replied with the answers listed: 1. What is the percentage of commercial customers you serve compared to residential customers? 25% commercial, 75% residential 2. Approximately how many heat pumps a year do you install? 250 3. Are heat pumps primarily installed in existing buildings or as part of new construction projects? 75% new, 25% retrofit 4. Who are the primary commercial customers you see installing heat pumps (i.e. schools, hospitals, municipal buildings) Our Design build customers and a very few others as Engineers do no spec. them as much as we do. 5. What is the most common reason why you think geothermal heat pumps aren't more commonly installed? (i.e. lack of design expertise, not enough qualified installers, high upfront costs, poor environment for heat pumps etc.) Up front cost and contractors, engineers being able to calculate ROI to show pay back. Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-15 6. What is the most expensive component associated with a typical ground source heat pump installation? What percentage of total project cost is the most expensive component? Equipment, but could be heat exchanger depending on design 7. Can you approximate what the installation cost is for a typical 20 ton, ground-source (closed- loop), water-to-air heat pump system installed in a commercial setting? What is the average payback on such a system? $60,000 4-5 years for additional cost over a conventional system, and 10-12 years total. 8. What are one or two key items you think would promote wider adoption of ground source heat pumps by commercial customers (i.e. up-front incentives, greater education through the utilities, more installer/design expertise, etc.) Incentives and educations, SHOW THEM THE MONEY – (ENERGY SAVINGS) Portable Classroom Controls: Product Offered (5) Web-enabled thermostat w/ integral web server can be connected directly to Ethernet cable in portable classroom. Product offers 366-day schedule capability with three different daily schedule types. Can be configured and locked remotely via internet – manual one-touch override if necessary. Even if portables already have programmable thermostats, rarely are they configured to account for vacation, summer, holidays on a regular basis since they must be manually configured in each portable. Web-enabled thermostat allows all to be scheduled at once and 366-day scheduling capability allows for vacation, summer scheduling. 1996 telecom act requires that every classroom have a portable computer, so plugging unit into Ethernet cable generally very easy (~30 min install) (6) Vendor offers Honeywell T7350B 366-day programmable thermostat. Offers setback capability during summer, spring break – pre-programmed holidays. Reduces nuisance callbacks over normal EMS systems or programmable thermostats with three separate stages of lockout. Each can be easily programmed through IR with a Palm Pilot. (7) Consulting Firm that offers Energy Management Services. Installed 90 Prophilix thermostats on contract for office building and dental office. (8) TCS Basys controls – offers 365-day thermostats that communicate via RS-232 interface. Usually put in new construction projects like small strip malls with 13-14 units that can be centrally controlled via internet. Costs (5) NT130 – Most popular for commercial, portable classrooms  $425 retail  Volume discounts are offered to school districts: 150+ @ $365 each, 400+ at $325 each. NT160 – more premium model with auxiliary relay that can be used to control OA dampers, lighting based on input occupancy schedule  Retail Cost = $499 Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-16 (6) $300 each + install costs (7) Typically $400 + installation costs for each thermostat. (8) SZ1033 – 2 stage Heat Pump thermostat w/ communications interface - $306 Comparable product – Honeywell T7350-1004 non-communicating - $138.50 Incentive Program Results (5) Xcel Energy (approved in CO, possibly pending in MN) and Puget Sound Electric offer incentives for these devices. Xcel Energy incentive makes up about 1/3 of total (equipment and labor install) and Puget Sound Electric makes up about 2/3 of total (equipment and labor install). Incentives of been very helpful for selling to school districts. Ideally, the incentives would be enough to buy-down the cost of 366-day web-enabled thermostat to the point where they cost the same as a standard programmable thermostat. School budget cycles are difficult to work with since they constrain how much money can be spent on a short-term basis and it is difficult to plan for upgrades on a long-term basis, so any incentive really helps them make the business case for existing or upcoming budgets. (6) Avista was running a program where they paid for the entire thermostat. As a result, all portable classrooms in Spokane and Couer d’Alene school districts were replaced recently. (7) Disappointed to see the SMUD ($50) incentive for programmable thermostats discontinued in 2006 and the PG&E ($100) incentive for programmable thermostats discontinued in 2008. Has been trying to get utilities to see the Prophilix device and other 366-day programmable thermostats as energy management systems and incentivize them accordingly. Marketing Approach (5) Direct Sales to School Districts. Usually sell equipment, districts install the units themselves. If wanted, Prophilix will contract with a national installer (Network Access Products) to go to the schools and install for a nominal fee. A proxy for market size is the growth of the area – generally rapidly growing areas have larger number of portables existing and being installed. Large market – estimated number of portables is: United States = 300,000 California = 80,000 Texas = 35,000 Florida = 35,000 (6) None discussed. Sounds like the sales of these thermostats into portable classrooms were a utility/school district initiative and not aimed at population at large or through a trade-ally network. (7) Offers these thermostats as part of total energy management service package to business, schools, etc. Incentives are a key to helping make the sale to customers who are skeptical of the controllers’ ability to save energy  uses energy management contract to monitor Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-17 and verify savings to customer. Believe incentives help overcome customers skepticism and become easier to convince. (8) No real market for 365 day programmable thermostats except in portable classrooms – even churches have daily activities and events that preclude use of 365 day programming capability. Any building that is occupied 95% of the time will just use a cheaper 7-day thermostat. Savings and Payback (5) Generally estimate a 9-12 month payback. Schools usually use internal labor to install which lowers upfront cost. Prophilix has assumed that going from a non-programmable thermostat to a programmable thermostat is about the same savings as going from a programmable thermostat (configured poorly or not optimized) to their web-enabled 366 day thermostat. As such, they use the EnergyStar calculator to get kWh estimates. BIG WARNING – your mileage may vary. (6) HUGE. A small study was conducted with the Avista thermostat replacement program. (7) For the dental office, saw monthly electricity bill reduced from 1200 – 850 kWh/month. Generally, would expect 15-30% savings. The following questions were sent to vendor (6) for response and the vendor responded with the answers listed: 1. Typical retail cost and installation cost of the T7350B thermostat. Referred to Dan Craner in SLC. 2. Any energy savings estimates for the recent upgrade to T7350B thermostats in the Spokane and CDA school district portable classrooms. Referred to Matt in the CDA school district (208-929-1028) 3. Do you see any types of customers other than schools installing these devices (i.e. contractors purchasing them for installs, facilities managers at commercial buildings, etc.) No response 4. Most often, do the T7350B thermostats replace existing programmable or non-programmable thermostats? Can replace any type of thermostat, has added benefit over 7-day t-stats to be able to schedule holidays, vacation. 5. Do you think an incentive would encourage customers and contractors to install more of these? Incentives are a big help, especially with school districts who would not shell out the extra cash for a 365 day programmable thermostat ordinarily.

(208) 852-2890 ID Number indicates a “yes” No number indicates a “no” or no response 1. Does your company have any experience or familiarity with these measures? 8+ T5HO High Bay Fixtures (1) (2) No. Work with 4-lamp and 6-lamp primarily (3) Only have worked with 6 Lamp – never used 8 Lamp Bi-Level Fixtures with Integral Occupancy Sensors (1) (2) Long daylighting in dairies – helps boost milk production. (3) Not used before. Probably good for areas where lighting needed for security, but want to reduce lighting load. Daylighting Controls (1) (2) Aware of it, but haven’t used it. Some customers have asked. LED Case Lighting (1) (2) Aware of it and it is available. Not used with customer yet. Distribute GE – which is all over the LED Case lighting. (3) No. Interested in learning more. Exit Signs (1) (2) Photolumeniscent/Tritium – rather do the LEDs since once you take possession of nuclear you own it forever. “Permalite” offers non-electric exit signs. (3) Worked with a few of them. Not a fan. Don’t want to mess with radioactive licensing, etc. LED fixtures are much better and cheaper than the $300 – 400 to install tritium exit signs. Misc. (2) Worked with LED in retail situations for PAR lamps. Still very expensive, but looking at 100,000 hours of life which makes it worth it. Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-22 2. Are there any other high-efficiency measures that you’re familiar with? (2) Program is pretty complete. Work mostly with 2, 3, 4 lamp 4 footers, 8 ft 2 Lamps and MH. (3) Probably. 3. How would you categorize the nature of the customers’ purchase of energy efficient products? For example, are they for emergency repair? Retrofit or remodeling? New construction? T5HO (1) New Construction – Warehouse, Manufacturing – mostly specified by engineers. Bi-Level (1) Structures that are limited maintenance, but require constant lighting for safety or other reasons Daylighting (1) More common with Green Design – mainly office structures, occupied 12 hours per day or less, and with lots of windows, multiple stories – try to add daylighting controls to lighting retrofits – most customers like the idea, but it adds cost (large control panels, rewiring, different low voltage ballasts and controls wiring). LED Case Lighting (1) Refrigerated cabinets, not used any yet – would save a lot of energy Exit Signs (1) Prefer LED – tritium is only for places where it is too expensive to transfer power – not real common, each sign must be registered with nuclear regulatory agency. Misc. (1) LED lighting is promising technology in the next 1-2 years. It currently is too cost- prohibitive. Extra incentive may be required to drive customers over the top. Building in IF looking to backlit with LED, but was cost-prohibitive and not installed. (2) About 15-20% of customer (mostly in Jackson Hole) request that lighting audit be performed and energy-efficiency lighting installed. Remaining customers must be approached about upgrading to high-efficiency lighting. (3) Just a matter of customer being aware of value of high-efficiency lighting. Manufacturers/ distributors don’t do a good job of advertising energy savings associated with high-efficiency lighting. 4. How many of these measures do you have available in your daily inventory? (1) Order all measures on a special order basis. (3) None. Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-23 5. For those that aren’t stocked, do you have any feel for the availability and lead times to obtain them? (1) High-bay lighting – 2-6 weeks depending on special options. Normal is 2-4 weeks. (2) Couple weeks. (3) All are special order. 1-3 weeks. 6. What percentage of your customers do you see installing these measures? (1) T5HO - <12% - majority are lower lamp counts or T8 high-bays. Really good efficiencies on high-bay reflectors– longer lamp life (3) Very small percentage - 8L T5 is possible – but 6L is more common. Very small percentage - tritium exit signs are possible in certain applications. 7. Can you estimate the average percentage incremental cost and customer payback for these higher-efficiency measures? (1) Depends on the baseline. There are many options. (3) Not easily. It is project specific. 8. What one or two key items could <Rocky Mountain Power (UT and ID), Pacific Power (WA and CA)> do to help increase the percentage of the measures installed by customers today? (1) Outdoor lighting is a potential market for high-efficiency lighting. Cold weather mini- fluorescents for soffit lighting a possibility for outdoor lighting (ballasts rated for - 20F), lighting level is as good or better, and have long-life. (2) Improve the lighting tool to allow more accurate estimates of savings. Currently, the tool uses a F34T12 as baseline for T12, when most fixtures are F40T12. Has the result of understating savings. Idaho Power and BPA lighting tool both allow F40T12 to be selected by user. For a school recently, RMP tool gave 33% savings but BPA tool gave 48% savings. Currently uses BPA sheet to calculate savings, then submits to Rocky Mountain Power for conversion to RMP lighting tool. Make all lighting tools between Idaho Power, BPA and Rocky Mountain Power use the same calculation methodology and establish uniform savings numbers. Provide a way to query customer rate schedule and billing rates in advance so lighting proposal to customer is accurate at the outset. 9. Is there anything else you would like to add that may help us with this effort? (2) Offer separate incentives for light retrofit or fixture replacement - If retrofit fixture – BPA has separate incentive that is lower ($30) than whole fixture replacement ($120) Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-24 A.9 MOTORS MEASURE VENDOR SURVEY RESULTS Table A-10 Summary of Motors Measure Vendors Vendor Phone Number State 1 KONE (EcoStart) (303) 342-0200 CO 2 Power Efficiency Corporation (702) 697-0377 NV 3 ProProducts, Inc.

Number indicates a “yes” No number indicates a “no” or no response 1. Does your company have any experience or familiarity with these measures? (1) EcoStarts (from Power Efficiency Corp) at Denver International Airport, Xcel rebates, $170-180 per unit. 30-40 hp, 160 units. Xcel Energy testing. First installations were in 1999. (2) Manufacturer (3) Yes, became familiar with new technologies like this after an effort in MN to produce energy efficient equipment. (4), (5) Yes, part of GMPG (6) Serves Hill AFB and ski resorts in UT. Quite familiar with Green Motors, about 5-6 years of experience. Did it all the time to avoid warranty issues and call backs. 1998 is when they got into it. Currently certified with GMPG and works for RMP generation systems. 2. Are there any other high-efficiency measures that you’re familiar with? (3) High-bay industrial lightings (4) NEMA Premiums, controlled burn-off, core loss testing helps efficiency. (5) Maintain efficiency, familiar with NEMA Premium (6) Raising or lowering hp on motors, systems approach. Aware of NEMA Premium speed increase. Currently involved with FX program. Aware of efficiency penalties especially on large motors and educates customers. 3. How would you categorize the nature of the customers’ purchase of energy efficient products? For example, are they for emergency repair? Retrofit or remodeling? New construction? (1) 95% retrofits, 5% new construction (2) Retrofit or upgrade remodeling (3) Retrofit and remodeling, though new construction is emerging. Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-25 (4) Emergency repair goes to new motors. Need 3 day turn around on Green Motors. Mostly retrofit basis. No inventory on green motors. (5) Not much new construction, mostly retrofit. Emergency repairs would use new motors. (6) Retrofit 4. How many of these measures do you have available in your daily inventory? (1) 2 in the location offices (2) Varies across the board. Inventory is usually readily available. Delivery is usually 2-3 weeks. Not usually too important because they aren’t being installed in emergencies. (3) About 7 (4), (5) Don’t stock. Motors are rebuilt as customers bring them in. 5. For those that aren’t stocked, do you have any feel for the availability and lead times to obtain them? (1) 1 or 2 days. Emergencies are not common because there is a bypass. (3) Lead time is 6-8 weeks. Microprocessor manufacturing and overseas shipping (manufacturer is UK based) delay orders. 6. What percentage of your customers do you see installing these measures? (1) A lot! (3) Escalator motor controller business is a low priority. Industrial motor controllers are their top priority. (4) Can’t say, they quote both new and Green motors and let the customer decide. Important to note that in order to remain competitive they do not charge extra for Green Motors. (5) Only offers Green Motors (6) Rebuilds are 100% if they can be done to original efficiency. If new is not available in time, will rebuild less efficient and go with that. Will order new and replace less efficiency rebuild when available. 7. Can you estimate the average percentage incremental cost, customer payback, or average life for these higher-efficiency measures? (1) 35% savings annually, 10, 15, 20 hp sizes. 15 hp is very popular (2) $1100 cost for 80% of the controls that are sold. (4) Although the customer is not charged a higher price, it costs the vendor 10% more to rebuild motors to Green Motor standards. They are unable to estimate customer payback because they are presently not charging anything more for green motors. Motors mostly fail for mechanical reasons such as bearings, etc. About the same life time as standard motors, 15-20 years. Generally any motor over 100 hp will be rebuilt rather than replaced. (5) 5-10% greater cost. Average life is as good as OEM, about 5-10 years. Appendix A General Vendor Survey Results 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho A-26 (6) 95% of the time it will be better than when it came in. Probably last longer than a new one. Sometimes motors have been rebuilt new to last longer. 8. What one or two key items could <Rocky Mountain Power (UT and ID), Pacific Power (WA and CA)> do to help increase the percentage of the measures installed by customers today? (1) Rebates, press releases, publicity on the savings. (2) Rebates, field representative support on sales calls. Green power and energy efficiency promotion. (3) Promote awareness of technology to our customer base. Incentives would be good. (4) Lead the way in advertising, trade magazines, and case studies. Incentives wouldn’t help much because they currently charge the same for green motors and new motors. (5) Rebates, customer education that rebuilt can be as good as new with Green Motors. It is not possible to rebuild an EPACT compliant motor into a NEMA Premium Efficiency motor due to design constraints. Emphasize recycling. (6) Incentives would be nice, but they are going to do Green regardless in order to avoid warranty issues. 9. Is there anything else you would like to add that may help us with this effort? (4) Doesn’t think green motors will be very effective until customers are educated as to what the impacts are. Top down education is necessary. (5) Keep paper work simple. Likes the sound of $2/hp (6) Keep mailings, email is good.

Savings data for compressed air measures was not reported by any of the reviewed resources and as such a table reporting estimated savings is absent. Due to the variability associated with HVAC equipment, the savings and cost data collected from the key resources and utilities was extremely varied and in some cases irrelevant. Savings data for HVAC measures was calculated and is listed in the body of the report. The cost data averaged from utilities and key resources is provided below. Customer cost estimates for irrigation measures was provided by vendors, and is therefore listed in Appendix A. Cost and savings data for motor measures is listed in Section 10 of this report and is therefore not included in this appendix.

provide a cost-effective means of enhancing program participation. Energy Efficiency Alliance participants have expressed confusion regarding the level of marketing allowed by the program, the process for approval of their marketing materials, and their ability to identify their business as a participant of the alliance. The following guidelines have been established as a draft set of procedures from which to build a final version for distribution. 1. Energy Efficiency Alliance Participants (Ally) may promote the availability of incentives from the FinAnswer Express program to customers who wish to upgrade their building or equipment. These guidelines apply to the program calendar year only. It is the Ally’s responsibility to review the guidelines at the beginning of each calendar year at www.rockymountainpower.net/idsave. 2. Ally shall not use Rocky Mountain Power’s or PacifiCorp’s corporate name, trademark, trade name, logo, identity or any affiliation for any reason (except as noted below), including soliciting customers, without Rocky Mountain Power’s prior written consent. This shall apply to, but not be limited to: seller proposal forms; envelopes; business cards; vehicle panels; telephone directories (including white pages, yellow pages and business directories); trade publications; advertising (including newspaper, radio and television); door-to-door flyers; clothing; briefcases; clipboards; billboards; or mailings. NOTE: Nexant recommends investigation of allowing a logo for use by trade ally that relates to the program. If the Rocky Mountain Power logo is not acceptable for use, consider the use of a specific program-level logo that pertains specifically to the program. In this case, additional description regarding the proper use of the logo would be substituted here. 3. There are some exceptions to the above usage rules. Participating allies may include the following pre-approved FinAnswer Express program copy in public promotional materials. Text listed in brackets {} is optional and may or may not be included at individual dealer’s discretion: ― “Take advantage of incentives from Rocky Mountain Power when you install qualifying high-efficiency {lighting,HVAC,etc}equipment” ― “Incentives available from Rocky Mountain Power for qualifying {lighting,HVAC,etc}equipment” ― “{ally name}, a participating vendor in Rocky Mountain Power’s FinAnswer Express Energy Efficiency Alliance” ― “Take advantage of incentives from Rocky Mountain Power when you install new {lighting,HVAC,etc}equipment” Appendix E Trade Ally Marketing Guidelines 2008 FinAnswer® Express Market Characterization and Program Enhancements – Idaho E-2 Websites If an ally website is co-branded, the page(s) that mentions Rocky Mountain Power must include a link to www.rockymountainpower.net/idsave. Approval Process Rocky Mountain Power will review ally materials at no cost. Any requests for such marketing should be made to the program administrator with a minimum of 10 business days to review and provide written approval. Cooperative Marketing Rocky Mountain Power will also work with equipment manufacturers and distributors to incorporate the Rocky Mountain Power name and logo into brand-specific materials for use by multiple allies. Any requests for such cooperative marketing should be made to the program administrator with a minimum of 10 business days to review and provide written approval.
