Please describe your work experlence with Idaho
Power Company.
I became employed by Idaho Power Company in
1996 as a Customer Service Representative in the Company
Customer Service Center.Over the first two years I handled
customer phone calls and other customer-related transactions.
In 1999, I began working in the Customer Account Management
Center where I was responsible for customer account
maintenance in the area of billing and metering.
TATUM, DI-
Idaho Power Company
In June of 2003, after seven years in customer
service, I began working as an Economic Analyst on the Energy
Efficiency Team.As an Economic Analyst, I maintained proper
accounting for Demand-Side Management (DSM) expenditures
prepared and reported DSM program accounting and activity to
management and various external stakeholders, conducted cost-
benefi t analyses of DSM programs, and provided DSM analysis
support for the Company s 2004 Integrated Resource Plan (IRP).
In August of 2004 , I accepted a position as a
Pricing Analyst in Pricing and Regulatory Services.As a
pricing Analyst, I provided support for the Company s various
regulatory activities including tariff administration
regulatory ratemaking and compliance filings, and the
development of various pricing strategies and policies.
In August of 2006, I was promoted to Senior pricing
Analyst. As a Senior Pricing Analyst my responsibilities have
expanded to include the development of complex financial
studies to determine revenue recovery and pricing strategies.
In my current position , I also provide regulatory support for
the Company s DSM programs and other DSM related activities.
What is the scope of your testimony?
My testimony will describe the purpose and
structure of a proposed performance-based DSM incentive pilot
program (Pilot), detail the proposed mechanisms for providing
performance incentives and penalties, and provide an estimate
of the financial impact of the proposed mechanisms.
Why is the Company proposing to implement a
performance-based DSM incentive pilot program?
TATUM, DI-
Idaho Power Company
Commission Order No. 29558 established Case No.
IPC-04-15 and approved the use of workshops for the purpose
of assessing the financial disincentives to investing in
energy efficiency by Idaho Power (Workshop). On January 27,
2006, Idaho Power filed an Application in Case No. IPC-04-
requesting authority to implement a rate adjustment mechanism
that would adjust the Company s rates upward or downward to
recover the Company s fixed costs, independent of the volume of
Company energy sales (FCA Mechanism). Within Case No. IPC-04-
15, the Company and other parties have filed a settlement
stipulation that would implement an FCA Mechanism on a pilot
basis. If the FCA Mechanism is approved by the Commission and
operates as expected, it will significantly reduce the
financial disincentives to investing in energy efficiency by
Idaho Power. However, during the Workshop process the parties
that signed the stipulation all agreed that with the FCA
Mechanism alone, the Company does not have an incentive to
pursue all cost effective DSM; it simply no longer has a
disincentive. At the suggestion of the Northwest Energy
Coali tion and others, the parties agreed that the Company
should test a performance-based DSM incentive mechanism on a
pilot basis. The performance-based DSM incentive mechanism
combined with the FCA Mechanism will create an economic
environment that will encourage Idaho Power to aggressively
pursue DSM resource acquisition.
If a performance-based incentive program is
desirable , why is the Company proposing a pilot program?
A. Introducing the performance-based incentive program
TATUM, DI-
Idaho Power Company
as a pilot program will allow the Company to test the effects
of the proposed performance-based DSM incentive mechanism on a
limited basis. The Company intends to learn from the pilot
with the ultimate goal of developing a broader performance-
based DSM incentive mechanism that can be applied to the
Company s entire portfolio of DSM programs.
How was the proposed pilot structure developed?
The proposed pilot structure is the result of a
collaborative effort between the parties involved in the
Workshop including representatives from the Company, the Idaho
Public utili ties Commission Staff (Staff) and the NW Energy
Coali tion.
Please describe the purpose of the proposed
performance-based DSM pilot.
The purpose of the pilot is to test the effects of a
performance-based DSM incentive mechanism designed to reward
the Company for executing its DSM program at a level that
exceeds agreed-upon goals and impose a penalty if the DSM
program s performance falls below its 2006 performance level.
The Company will not earn an incentive or a penalty for DSM
program performance between the goal level and the historical
level. In the Pilot, the performance incentive and penalty
mechanism will be tested on one of the Company s current DSM
Programs.
What is the proposed effective period of the pilot?

operational performance be evaluated?
The operational performanceCompanyDSMprogram
will be evaluated annually for the purpose of determining an
incentive or penalty under the proposed pilot structure.
Which DSM program does the Company propose to use
for the pilot?
The Company proposes to use the ENERGY STAR~ Homes
Northwest program in the pilot.
Please provide a brief description of the ENERGY
STAR Homes Northwest program.
ENERGY STAR Homes Northwest is an incentive-based
program that encourages the onsite construction of energy
efficient single-family homes. ENERGY STAR Homes Northwest is
the program currently operated by the Company to acquire the
resources identified in the Residential New Construction
Option in the 2004 IRP. This program was developed by the
Uni ted States Environmental Protection Agency/Department of
Energy, the Northwest Energy Efficiency Alliance (NEEA) and
Pacific Northwest electric utili ties.There are three
implementation partners for this program in the Company
servlce territory; NEEA , Idaho Energy Division (lED) and Idaho
Power.

Idaho normally establishes cost-effectivePower
energy savings targets for its DSM programs through the IRP
process. Why has the Company adopted a different goal setting
method for the pilot?
The establishes long- termCompanyIRPprocess
energy savings goals for DSM programs based on assessments of
DSM potential and load forecasts. The long-term nature of the
IRP energy targets does not allow for annual adjustments to
for economic variabili ty from year.Theaccountyear

TATUM, DI-
Idaho Power Company
It was suggested by Staff during the Workshop that
the NEEA market-share goals for 2007 through 2009 would
establish a good target for the pilot,it would align Idaho
Power program targets with NEEA' s goals for ENERGY STAR
Homes in the region. Furthermore, by achieving NEEA's market-
share goals for utility funded ENERGY STAR Homes,the Company
will also meet its IRP energy savings targets for ENERGY STAR
Homes.

Is the tracking of building permits as a determinant
of the single-family home construction totals consistent with
NEEA's method for deriving its market-share projections?
itsYes.NEEA states RSI Newpage
Construction Renewal Proposal dated June 26,2006 that single
family home construction permits form the basis of its market-
share proj ections
At what performance level will the Company incur a
penal ty under the proposed pi lot?
The Company will be subj ect to a penalty when the
ENERGY STAR Homes Northwest program fails to reach the market-
share percentage achieved by the program in 2006. The program
is expected achieve a market-share of 4.9% in 2006.The 2006
market-share percentage is calculated as the number of Idaho
Power-funded ENERGY STAR Homes constructed in 2006 divided by
the number single family home building permits recorded
within Idaho Power s service area in 2006 as reported in the
Wells Fargo Bank Idaho Construction Report ( 400 ENERGY STAR
Homes 7 8,185 Total Homes = 4.9%).
How does the Company propose to compute the
incentive and performance penalty through the pilot?
Whenever the Company s DSM program operational
performance is at a level that triggers an incentive or
TATUM, DI-
Idaho Power Company
penal ty, both the incentive and penalty dollar amounts will be
derived as a percentage of the present value life-cycle net
benefi ts of the DSM program from a Total Resource Cost
perspecti ve.A program s net benefit represents the dollar
difference between the present value life-cycle gross benefits
of the efficiency measures installed and the Total Resource
Cost. If program performance falls between the penalty
threshold and the performance goal, the Company will not earn
a penalty or incentive.
What is the Company s preferred method for
quanti fying the gross benefits of a DSM program?
Idaho Power calculates the gross benefits of a DSM
program as the present value life-cycle energy savings
resul ting from a DSM program based on the avoided energy cost
of the next best generation alternative as reported in the
most recent IRP.
The DSM Alternative Costs in Table 3 below represent the

Does the Company plan to use the energy savings per
home estimates from the Ecotope Consulting study to quantify
the energy savings achieved each year under the pilot?
No. The energy savings per home estimate of 2,078
kWh annually as measured at the meter or 2 305 kWh including
line losses has been used only in analyses of potential
effects of the pilot. The Company or a third-party consulting
firm will conduct an updated evaluation of ENERGY STAR Homes
Northwest program energy savings during 2007. The updated
evaluation results will serve as the basis for the
quantification of the energy savings achieved by the program
throughout the remainder of the pilot.
What are the expected program costs for ENERGY STAR
Homes Northwest required to achieve the 7.0% market-share goal
for 2007?
TATUM, DI-
Idaho Power Company
The ENERGY STAR Homes Northwest program costs for
2007 are estimated at $850,000 and will be funded through the
Idaho Energy Efficiency Rider (Rider). Program costs funded by
the Rider include the cost of planning, developing,
implementing, monitoring and evaluating DSM programs included
in the pi lot.Evaluation costs of the programs in the pilot
are not to exceed 5% of program costs and will be included in
the cost-effectiveness calculation.The Total Resource Cost,
which includes the cost to a customer for participating in the
program, is estimated to be approximately $1 100,000 in 2007.
Will a portion of the costs associated with NEEA' s
regional ENERGY STAR Homes initiative be included in the
calculation of Total Resource Costs in the pilot?
No. While NEEA's regional ENERGY STAR Homes
initiative contributes to the success of the Company s current
program, NEEA's ultimate goal for its current expenditures is
a transformed market where ENERGY STAR homes are constructed
without receiving utility incentives. In order to achieve its
market transformation goal, NEEA is making investments today
to develop a support network for the construction of ENERGY
STAR homes. These investments include, but are not limited to,
the training of ENERGY STAR home builders and inspectors,
energy efficiency research and supporting improvements in
building codes and efficiency standards. Each of these
activities benefits the Company s current program while
building a foundation for future energy savings. Since it is
difficult to determine what share of the NEEA expenditures
benefi t utility progams and what share results in market
TATUM, DI-
Idaho Power Company
transformation savings, NEEA and its members have agreed to
keep the accounting of costs and savings associated with NEEA
initiatives separate from the accounting of utility program
acti vi ties.
If the Company s ENERGY STAR Homes Northwest program
exceeds its market-share goal during the Pilot , how will the
Company s percentage share of the program s net benefits
(incentive) be determined?
The propo s ed performance incentive design uses
sliding scale approach that increases the incentive amount as
program performance increases.As can be seen from the detai
in Table incentive would be awardedbelow,performance
when the market-share achieved exceeds 100%the target
level.The incentive amount awarded increases for each whole
percentage point over the market-share goal and will be capped
at 110% of the goal.

Share Program Net Benefits (TRC)1. 0%10.
I f the Company s ENERGY STAR Homes Northwes t program
fails to achieve its minimum market-share threshold of 4.
during the pilot, how will the Company s penalty amount be
determined?
Like the incentive determination , the penalty will
be calculated as a share of the program s life-cycle net
benefits from the Total Resource Cost perspective. However , in
TATUM, DI-
Idaho Power Company
the penalty calculation , the Company will pay a fixed 50%
share of the "lost" net benefits resulting from the
unsatisfactory performance level. Lost net benefits are
equivalent to the difference in the net benefit amount that
would have occurred had the program performed to the minimum
market-share level and the actual net benefits at the lower
performance level. For example, if the ENERGY STAR Homes
Northwest program achieves a 2.5% market-share level in 2007
resul ting in net benefits of $100,000 and the net benefits at
9% market-share threshold are equal to $150,000, the penalty
amount would be $25,000 or 50% of the difference in net
benefi ts.
What is the range of potential incentive and penalty
payouts at various program performance levels?

pilot as applied to the Company s ENERGY STAR Homes Northwest
program market-share goals for 2007.The estimated incentive
and penalty amounts shown in Columns E and F of Table 5 are

If Company earns an incentive or incurs a penalty
during the Pilot, how will the amount of the incentive or
penalty be transferred between the Company and its customers?
Should the Company earn an incentive or incur a
penalty under the pilot , the dollar amount of the incentive or
penalty will be determined by the Company and submitted for
Commission review no later than March 15 of each year. Upon
Commission approval , any incentive amount will be applied as
an additional energy rate to all customer classes over a 12-
month period beginning June 1. Conversely, any penalty amount
will be applied as a reduction to the energy rate over the
same period. The resulting dollar amount applied to customers
bills will not appear as a separate line item on each bill.
For the purpose of bill presentment, the dollar amount will be
combined wi th the existing "Conservation Program Funding
Charge " line item.
TATUM, DI-
Idaho Power Company
Is it your opinion that the implementation of the
proposed pilot is in the public interest?
Yes. The proposed Pilot will provide an environment
where the incentive mechanism can be tested on a limited basis
to determine its potential to encourage the Company to
aggressively pursue cost-effective energy efficiency.
Furthermore, the pilot is consistent with the National
Action Plan for Energy Efficiency introduced last summer and
endorsed by many entities including the National Association
of Regulatory Commissions and the Edison Electric Institute.
Does this conclude your testimony?
Yes it does.

RSI New Construction Renewal Proposal
SUMMARY:
Project Name:RSI New Construction
Sector:Residential
Market:New single-family residential construction
Description:Residential new construction includes promoting a market-
based component called ENERGY STAR Homes Northwest
well as efforts to demonstrate emerging products and
improve codes and code implementation. ENERGY STAR
Homes Northwest is based on EP A's ENERGY STAR brand
for new homes, adapted to meet the unique needs of the
Northwest. The ENERGY STAR label serves as the
mechanism to both differentiate builders and the homes they
build as well as to provide consumers with an easy way to
identify the home as efficient. Marketing and home
certification and labeling efforts are designed to increase the
market share of ENERGY STAR homes.

IMPLEMENTATION: Strategy and Approach
Status through 2005:
The first two years of the Residential New Construction component has been focused on bringing
ENERGY STAR Homes to the market. The market actors are largely relying on the Alliance, its
contractors and utilities to achieve success in the market. We have been focused on building the
market infrastructure, signing on builders and moving homes through the certification process.
During that time period the following has been accomplished:
Established a solid infrastructure of verifiers and performance testing technicians.
Established processes for certification and quality assurance that are working and are
continuously examined for improvement in efficiency and effectiveness.
Signed 305 builders total in 2004 and 2005. Market Progress Evaluation Report 2 indicates
participating builders are currently satisfied with the initiative.
Certified 988 homes in 2005 and 57 homes in 2004.
Developed and implemented key components of the marketing elements and gained
participation from builders, HV AC contractors and verifiers.
Established relationships with national market players such as the EP A and RESNET
(Residential Energy Services Network - a national organization of professionals providing
energy analysis and consulting for existing and new residential construction).
Progress Planned for 2006
In 2006 the new construction component will add to this success in the following ways:
Fill in the gaps that exist in some geographic areas for performance testing and verification
infrastructure.
Gain more participation from the existing builder base in co-marketing and selling Energy
Star homes to the consumers.
Begin to engage the HV AC community in selling the ENERGY STAR Homes brand.
Leverage the federal tax credit program to establish a higher bar for potential future
ENERGY STAR Homes Northwest specifications and gain incremental savings. Utilize
demonstration proj ects to assist with this effort.
Begin to establish manufacturer relationships in lighting and HV AC and develop co-
investment opportunities with these players.
Engage the Realtor community in selling ENERGY STAR Homes.

Leverage EP A funding and local utility efforts for increased consumer marketing.
Support builders in successfully meeting the lighting requirement through builder and
verifier trainings and showroom support.
Objectives and Strategies for 2007-2009
The objective for the renewal period will be to achieve 14% market share by the end of20093 and
to have the marketplace take ownership ofthe ENERGY STAR Homes initiative s success.
Encouraging the verifiers and builders and other market actors to take ownership of the success of
this effort is a critical step in market transformation and the first step of a long-term exit strategy.
The new homes team will continue to recruit ENERGY STAR builders but increase efforts to
enable HV AC contractors and verifiers to recruit the builders. In addition, more emphasis will be
placed on engaging the lighting and HV AC channel in promoting ENERGY STAR Homes.

* Total Homes Estimated are derived as follows: 2004 single family permits
pulled from the 2004 Census. 2005 numbers assumed a 10% increase based on
data through mid year. 2006 through 2009 assumes a 3.85% growth based on
Northwest Power Plan. ENERGY STAR market share is for certified ENERGY
STAR homes only.
The following strategies will be pursued to achieve this objective:
Homebuyer Market
Leverage Alliance funds to obtain co-investment from EP A and utilities for consumer
advertising.
Continue to focus marketing efforts primarily on reaching current homebuyers vs. broad
based consumer marketing.
3 The 14% market share goal has been reduced from the origina120% goal (as indicated in the Project Description for
ENERGY STAR Home Northwest dated July 10 2003) as a result of2 years of program start up experience. This
adjustment is due to full program roll out completing approximately 10 months later than anticipated and the sales
cycle to bring a builder on board and fully transition their building practices to the ENERGY STAR standard is longer
than fIrst anticipated.

Builders, Realtors, Lenders and Appraisers
. Move beyond the recruitment of builders who are early adopters, those who use the brand
to differentiate themselves, to the early majority, those builders who begin to sign on
because they want to be a part of the success.
Increase builder participation in marketing ENERGY STAR homes to consumers.
Continue to engage the Realtor community in selling ENERGY STAR Homes.
Engage the lending and appraisal industry to recognize the increased value of ENERGY
STAR Homes.
Heating and Cooling (HV AC)
Fully engage the HV AC contractors in pro actively selling ENERGY STAR Homes
Northwest as a means to improve their profitability. Primary focus will be dedicated to
their support of the ENERGY STAR Homes specification, however these efforts will also
support component improvements in the new homes market place.
Dramatically increase participation and co-investment from HV AC equipment
manufacturers. Participation might include sponsoring training for builders and HV
contractors, providing manufacturer rebates on equipment or co-investing in consumer
marketing or builder marketing activities.
Lighting4 and Appliances
Continue to work with builders and verifiers to ensure quality installations of ENERGY
STAR lighting.
Continue to work with manufacturers, lighting showrooms and electrical distributors to
ensure quality products are available for builders.
Engage manufacturers and showrooms in pro actively supporting ENERGY STAR lighting
in new homes.
Work with builders and manufacturers on promoting ENERGY STAR appliance packages
to new homeowners.
Support the use of lighting fixtures to meet the specifications of ENERGY STAR Homes
Northwest in those markets where utilities are supporting the sales oflighting fixtures.
Work with the Puget Sound area utilities on a fixture pilot that works with lighting
showrooms and distributors to improve their support of ENERGY STAR fixtures sales.
Verification, Certification and Quality Assurance
Develop the verifier network to be professional, proactive, self-sustaining businesses.
. Move to a point where certification fees, training fees and HV AC manufacturer support
fully fund the training, QA and certification aspects of the initiative.
Incorporate quality assurance results into builder, verifier and HV AC training to ensure
continuous improvements in the quality of ENERGY STAR Homes.

Market Outreach, Coordination and Marketing are currently elements of the new construction
component. Market Outreach includes staff dedicated to selling, educating and supporting builders
and HV AC contractors as well as travel expenses associated with the outreach activities. 6 FTE is
currently budgeted for this category.
Coordination expenses include staff dedicated to managing the new construction component
database support, internal builder support and utility coordination.
Marketing expenses included co-op ad funds, public relations support, advertising dollars, builder
training materials and merchandising materials. The team will work to maintain as much
marketing funding as possible to address the need for additional consumer education as
recommended by the Market Progress Evaluation Report 2.
Technical support services are provided by the State Certification Organizations: Oregon Depart of
Energy (ODOE), Washington State University Energy Services (WSU), Idaho Energy Division
(lED) and National Center for Appropriate Technology (NCAT) in Montana. These services
include quality assurance, certification, verifier training and support and HV AC performance
testing training and support. This budget category also includes demonstration proj ects in Idaho
and Montana for the 2007 time period. (Oregon and Washington are scheduled for 2006.) This is
the net Alliance funding after revenues from certification fees for each home certified ENERGY
STAR are netted out.
Lighting budget includes lighting support for builders; showroom, distributor and manufacturer
engagement ; and the promotion of appliance packages to homebuyers' purchasing appliances
beyond the built in appliance spec for ENERGY STAR Homes Northwest. It also includes
$40 000 allocated to the ENERGY STAR Fixture Pilot in New Construction in 2007 and 2008.

The new construction component of the RSI initiative brings in certification fees as project
revenue offsetting the costs of technical support, quality assurance and certification from the State
Certification Organizations. Over the course of the 3 year period Alliance funding support is
reduced and certification revenue increases to offset reduced Alliance expenditures as pictured in

Cost Effectiveness
Energy Savings. The RSI Energy Star New Homes project was modeled for cost-effectiveness on
the basis of a weighted average cost and savings across three different building types (1 800 ft
200 ft2 and 3 300 ft , five climate zones (Portland, Seattle, Spokane, Boise, and Missoula) and
four heating system types (heat pump, zonal electric, gas with air-conditioning, gas without air
conditioning). Table 1 below indicates the average electric and gas savings by heating system
type. It also indicates the amount of savings allocated to lighting in each of the homes.

Using the data and weights in Table 1 , the regional average savings per home amount to 1 533
kWh/yearlO and 131.4 therms/year.
Costs. Using the same weighting and incremental first costs, the weighted regional average
incremental first cost of the Energy Star Home is $1 349 per home. Because the home represents a
package of measures, some of which will last for the life of the home and others with much shorter
life, the cost of replacements are modeled and then computed as a present value which is added to
the incremental first cost of the home in the ACE model. Including this present value
replacement costs raises the total cost of the weighted average home to $2 373.78.
8 Savings for heat pumps are based on the increment between HSPF 8.5/SEER 13 and the new federal standard of HSPF
7/SEER 13.
9 Air-conditioners in gas homes are modeled as SEER 13 units in both Energy Star and base case; savings result only from
reduced internal gains from lighting and lower fan energy from reduced fan run time due to reduced leakage in ducts.
10 CFLs contribute to savings at 992 kWH/year/home with HV AC Interactions that result in net savings of 795 to 1052
kWh depending on the HV AC system type.

Market penetration of all homes built to ENERGY STAR Homes Northwest standards (including
baseline homes) is estimated to grow from just over 1 % in 2005 to 14% by 2009 and to 34% by
2015. Utility and baseline units make up the majority of the units in 2007-2009. Utility units are
forecasted to level off as the market share increases beyond 20%.
A more detailed summary of the cost-effectiveness analysis is included in Appendix A.
Evaluation
The RSI Energy Star New Homes project evaluation for 2007 - 2009 will include three MPERs
and an Impact Evaluation report. The evaluation will measure the project's progress toward the
goals stated above.
In addition, the following measurable progress indicators will be tracked as indicators of market
progress:
Builders use the ENERGY STAR label to differentiate themselves in the marketplace.
. Consumers, builders, and other market actors link ENERGY STAR homes and home
quality/value.
Builders are convinced of the long-term cost savings from reductions in call-backs that
should result from performance testing and quality assurance practices;
Increased awareness by builders and subcontractors of key efficiency and quality issues.
Other market actors and trade allies are spending their own resources marketing ENERGY
STAR Homes and matching Alliance investments.
Builders and their subcontractors have expanded knowledge and skills necessary to treat
key energy efficiency and quality issues, particularly performance testing ofHV AC ducts
and equipment.
Increasing recognition of the ENERGY STAR label and understanding what it means for
new homes.

Multiple Listing Services include whether a home is certified ENERGY STARin their
listings.
The value of efficiency upgrades is automatically included in the appraisal process.
Residential energy codes are upgraded to incorporate some or all of the current ENERGY
STAR requirements.
A new level of efficiency for ENERGY STAR is adopted based on successful
demonstration of new and emerging technologies.
ENERGY STAR home purchasers are highly satisfied with their homes and recommend
them to others
Evaluation Components
The ENERGY STAR Homes evaluation for 2007-2009 will include the following components.
Table 2 shows the anticipated schedule for conducting each of these components.
Process Evaluation/Assessment: The evaluator will summarize project activities since the
previous MPER based on status reports, in-depth interviews with key market actors (such as
builders, verifiers etc); contractor staff and proj ect contractors. Findings will be incorporated into
each MPER.
Market Characterization: Evaluation reports will include a review of current conditions in the
new home market including potential market size and market share; and forecasted market growth.
Data from the tracking database will be analyzed in conjunction with the market characterization
to estimate ENERGY STAR current and projected market share.
Homebuyer Survey: A third wave of the homebuyer survey previously conducted in 2004 and
2006 will be conducted in 2008. The survey will track progress on homebuyer awareness
knowledge, understanding, attitudes, and purchasing behavior surrounding ENERGY STAR
homes. This includes general awareness and understanding of the ENERGY STAR home label and
its meaning, and the value placed on the various benefits offered by ENERGY STAR homes.
Builder Survey: A third wave of the builder survey previously conducted in 2004 and 2006 will
be conducted in 2008. The survey will track builder knowledge, attitudes, and sales behavior
regarding ENERGY STAR Homes as reflected in their attitudes and perceptions ofthe ENERGY
STAR homes label, marketing efforts, and individual efficiency components such as duct testing
and sealing. Satisfaction with the ENERGY STAR Homes Northwest component will also
be measured.
Market Actor Interviews: In-depth interviews with builders, contractors, verifiers, lighting
market channels, and project staff will be conducted each year in order to gain an in-depth
understanding of ongoing market barriers and opportunities. This information will be used to
inform the process evaluation and adaptive management process.
Post-Occupancy Survey: A post-occupancy survey will be conducted in 2007 to assess purchaser
satisfaction with ENERGY STAR homes and to determine the retention rate of CFLs, which are a

critical component of electricity savings. The evaluator will attempt to conduct these surveys on-
site to allow the most reliable possible measurement of CFL retention.
Impact Evaluation: The evaluator will initiate an impact evaluation in 2007 that will provide an
analysis of actual realized savings per ENERGY STAR new home, based on homes constructed in
2006-2007. This effort will include a field survey to characterize the building and occupant
characteristics ofES new homes in the region, and may include sub-metering of homes with heat
pumps. It is assumed that the Residential New Construction Building Characteristics Study will
serve as a baseline for this impact evaluation.

Contracts.
This project is part of the Residential Project Management Contract (PMC) which was
competitively bid in late 2003 and awarded to PECI in 2004 and extended through 2006. While
implementation of a majority of the project is through the PMC contract, the Alliance contracts
with each of the state energy offices (ODOE, WSU, lED and NCAT) to implement the
certification and quality assurance components. Current contracts run through 12/31/06. The
Fixture Pilot Program funding for 2007 and 2008 of $80 000 will be combined with Bonneville
funding and competitively bid separately.

Staff recommends a competitive bid of the PMC work through 12/31/09. Staff recommends
extending the sole source contracts of the state certification organizations (ODOE, WSU, IDWR
and NCAT) on an annual basis. These state agencies are uniquely qualified to provide credible
quality assurance and local technical expertise and code integration. The nature of these contracts
is such that fees collected from market actors for certification and QA of homes and for training
are supplementing and will eventually replace Alliance funding.
Alliance Internal Resource Requirements.
Internal resources required to manage this project are estimated to be approximately 1.0 FTE.
These resources are assumed to be available within current staffing levels approved by the Board.
Local Utility Coordination.
This initiative assumes a high degree of coordination with local utilities and is designed
accordingly. It is also designed to work with the full range of potential utility interest from full
implementation to complete lack of participation. There are a number of areas of utility interaction
with this initiative. These include, but are not limited to the following:

There are a number of stakeholders engaged in this market. First, the state energy offices and
similar entities (Idaho Department of Water Resources Energy Division (IDWR), Montana
Department of Environmental Quality, National Center for Appropriate Technology, Oregon
Department of Energy, and Washington State University Energy Program ) have been working
with the national level Energy Star program as well as the regional Energy Star manufactured
housing.
Additionally, the Alliance is coordinating with the EP A and RESNET (Residential Energy
Services Network) to ensure the Northwest is aligned with national programs and is up to date on
new national developments. Each ofthe State Certification Organizations are RESNET approved
providers. The Alliance and CSG are RESNET members as well.
