REQUEST:
On page 8 of its 2019 Impact Evaluation, Cadmus describes its non-residential program sampling
methodology. For each of the programs listed in Table 7 (page 9), please provide the workpapers
used to determine sample size in electonic format with formulae and links intact. For each
progrcm, please include the population variance (or standard deviation) assumed in the calculation
as well as the source for that variance (or standard deviation). If any methodology other than
simple random sampling was used (e.g. stratified sampling or cluster sampling), please describe
the methodology and explain the rationale for its use.
RESPONSE:
Sta[PR_4l Attachment A shows the confidence and precision assumptions that were made for
each program and fuel type. It also includes the tracking of population for each program by
sampling wave. Note that the 2019 sample was part of the total 201 8-201 9 period, so it is inclusive
of two years of population.
Staf[_PR_4l Attachment B (CONFIDENTIAL) and StafLPR_4l Attachment C
(CONFIDENTIAL) contain the population for sampling waves 3 (January 2019 to June 2019) and
4 (July 2019 to December 2019). Each tab represents a program and contains a listing of the
population as well as the sites selected by Cadmus. Each sample also includes specifications
regarding whether the sample is made with certainty or randomly; further notations are included
for each certainty selection to explain the reason why that particular sampling was with certainty.

RBQUEST:
On page 20 of its 2019 Impact Evaluation, Cadmus states that the Multifamily Direct Install
"MFDI ldaho participant group showed a reliable relative precision estimate of +/- 17% atthe9}Yo
confidence level for the34 facilities included in the analysis and savings of 5.80/o." Please provide
all workpapers (in electronic format with all formula and links intact) and data showing how these
estimates were determined.
RESPONSE:
Please See Staff PR_42 Attachment A (CONFIDENTIAL) for the workpapers requested above.
The tab labeled "Facility_Type_Summary_State" shows the 2018 data in row 12. Please note that
Cadmus utilized the 2018 participation data for 2019 due to insufficient data from 2019.
With regard to 2019 data, the "part 2019" (row 9) group is a subgroup that installed MFDI
measures in 2019 but installed too early to be put in the nonparticipant group. Because they
installed in2019, these participants have the minimum number of post months (10 months post)
and, on average,have only 300 post days, which is the minimum allowed number of days. Cadmus
did not use this group because there was a constant misbalance between number of days pre (365)
and post (300) and this could potentially skew results.
