Design
for Excellence
Impact Evaluation |
For
Southern California Edison, ADM developed
detailed estimates of the impacts of the Design
for Excellence Program, SCE's commercial new
construction DSM program. The analysis quantified
the following post-implementation impacts: first-year
savings, load shape changes, and net adoption
rates. ADM defined a strategy for selecting
program participants for the impact evaluation
sample. ADM then conducted phone interviews
with a sample of decision-makers to determine
their criteria for participation in the program.
Title 24 documents were also collected for projects
within this sample. High-resolution on-site
surveys of 100 participants provided the data
for DOE-2 runs correlated to billing data and
local weather data. Additional parametric runs
compared the energy-use of the buildings under
various Title 24 conditions and the as-built
conditions. The data from the decision makers'
survey was combined with the results of the
DOE-2 parametric analysis to inform the overall
net-to-gross analysis for the program. |
| Title-24
Plus Measurement and Evaluation Impact Study |
ADM
performed a study to develop quantitative estimates
of the impacts of San Diego Gas and Electric's
Commercial New Construction Program, whose technical
requirements exceeded California's Title 24
building energy-use criteria. The purpose of
the study was to assess the actual (realized)
impact of several post-implementation program
parameters; first year annual energy savings,
load shape impacts, net-to-gross and persistence
impacts, incremental customer equipment and
installation costs, and total customers' costs.
Samples of program participants and nonparticipants
were chosen and a survey designed to compare
the energy-use of these groups. Realized savings
are being evaluated for the two groups using
data on building equipment and characteristics,
economic and attitudinal characteristics of
the businesses involved, and billing and/or
end-use metered data. On-site data-collection
was used to collect "as built" information
not available from existing sources. Monitoring
equipment was installed on a subsample of the
buildings visited. Metered electricity end-use
data were collected that reflected equipment
"as-operated" conditions. |
| Commercial
Audit Impact Evaluation |
ADM
was a subcontractor for the evaluation of Consumers
Power's Commercial Audit and Bonus Program.
The primary goal of the evaluation is
to estimate the gas and electricity energy and
demand savings of the program.
ADM conducted on-site engineering audits
for a sample of 30 commercial sites, and was
responsible for reviewing the engineering assumptions
for 170 commercial sites; analyzing and reporting
on the kWh and kW energy savings for the program
participants. |
| Residential
Audit Program Impact Evaluation |
ADM
was a subcontractor for the evaluation of Consumer's
Power Residential Audit Program.
CPCo's residential program offers energy- efficiency information,
rebates for customer-installed energy-efficient
measures, and direct installation of low-cost
energy-efficiency measures. The primary objective
of the evaluation was to determine the energy
impacts of this program.
ADM developed a sample for on-site verification
audits, conducting on-site audits, and reported
on the effectiveness of the program. |
| Residential
New Construction Impact Evaluation |
ADM
was a subcontractor for the evaluation of Consumers
Power's Energy Wise Home Builder Program.
ADM was responsible for designing the
sample for participating and nonparticipating
homes, conducting detailed on-site audits of
30 homes, performing engineering simulations
of energy use based on the on-site-collected
data, and reporting on the kWh and kW impacts
of the program measures. |
| Evaluation
of Energy Smart Design Program |
ADM
conducted an evaluation of the gross and net
savings impacts of
Portland General Electric Company’s Energy
Smart Design Program, a new-construction DSM
program for the commercial sector.
Estimates of the gross savings in energy
use for buildings participating in the ESD Program
were derived through comprehensive engineering
analysis of the energy use for a sample comprised
of both participant and nonparticipant buildings.
Complete data on the building and equipment
characteristics and the operational practices
of the sample buildings were collected through
on-site visits.
For each building in the sample, the
data collected on-site were used in a series
of parametric simulation runs with the DOE-2
building energy analysis model to develop estimates
of annual whole-building and end-use energy
use under different sets of building conditions.
The gross savings attributable to measures installed
under the ESD program were then determined through
comparisons of a building’s whole-building and
end-use energy use with and without the rebated
measures installed.
Net-to-gross ratios for determining the
net energy savings of the program were derived
both through survey-based estimation methods
and through econometric methods. |
| Evaluation
of New Building Design Program |
ADM
prepared an impact evaluation of the gross savings
achieved by B.C.
Hydro’s New Building Design (NBD) Program.
Estimates of the gross savings in energy
use in the new commercial buildings participating
in the NBD Program were derived through comprehensive
engineering analysis for a sample comprised
of both participant and nonparticipant buildings.
Complete data on the building and equipment
characteristics and the operational practices
of the sample buildings were collected through
on-site visits.
For each building in the sample, the
data collected on-site were used in a series
of parametric simulation runs with the DOE-2
building energy analysis model to develop estimates
of annual whole-building and end-use energy
use under different sets of building conditions.
The gross savings attributable to measures
installed under the NBD program were then determined
through comparisons of a building’s whole-building
and end-use energy use, with and without the
rebated measures installed. |
| Evaluation
of the Large Commercial/Industrial Retrofit
Program |
ADM
conducted comprehensive process and impact evaluations
of Green
Mountain Power Company's Large Commercial
and Industrial Retrofit (LCIR) Program. Data for the evaluations were obtained via: a telephone survey
of all participants, on-site data-collection
at the facilities of the 10 participants that
were responsible for 85% of the program’s impacts,
selected end-use metering (using compact data-loggers)
at 6 facilities, staff interviews, and a detailed
review of all records, correspondence, and other
documentation.
The impact evaluation was based on an
independent assessment ¾
using engineering analysis ¾
of both electricity savings and fuel-use increases
produced by each measure installed because of
the program at each of the 10 facilities, plus
an analysis of free-ridership and other parameters
relevant to a gross-to-net adjustment. |
| Evaluation
of the High-Efficiency Motors and Adjustable
Speed Drives Rebate Programs |
ADM
performed process and impact evaluations of
two of Cincinnati
Gas and Electric Company’s commercial and
industrial DSM programs. Through these programs,
customers receive rebates for installing high-efficiency
motors or ASDs.
We are collecting data via a telephone
survey of a sample of participants, staff interviews,
and records/documents review.
An engineering analysis was used to estimate
the energy and demand savings achieved by the
programs. |
| Process
and Impact Evaluations of the Smart Light
Program |
ADM
is currently performing process and impact evaluations
of Brooklyn
Union Gas Company’s 1994 Gas Cooling Rebate DSM program, and has completed a
process evaluation of BU’s newly introduced
Gas-Engine Drive Pilot Program.
(In 1995, process and impact evaluations
of both programs will be performed.) Both programs are focused on commercializing new technologies
(gas-fired absorption-cycle chillers smaller
than 10-tons and all equipment larger than 100-tons
are not eligible for BU’s rebates).
An interesting feature of the evaluations
of these programs is that Consolidated Edison,
the electric utility that serves the same customers,
also offers a rebates for converting from electric-motor-driven
equipment to gas-powered equipment.
The impact evaluations (which are based
on both a billing analysis and an SAE analysis
of both gas and electricity billing records)
will take into account both electricity savings
and gas-usage increases. |
| Impact
Evaluation of New York State Energy Star Program |
ADM
conducted process and impact evaluations of
the Smart
Light Program that Conowingo
Power Company (CoPCo), a subsidiary of PECO
Energy, offers in its Maryland service territory.
Under the program, residential customers
can order (via either mail or telephone) up
to 5 compact fluorescent lamps (CFLs) for only
$5.00 each, plus a $3.00 shipping charge.
As of the start of the evaluation in
June, 1994, more than 2000 customers had participated
in the program, and more than 9,000 CFLs had
been distributed.
The objectives of the evaluation were
to develop: (1) estimates of the program's demand-reduction
and annualized energy-savings impacts, and (2)
assessments of (a) the adequacy of the program's
design and implementation procedures, and (b)
customer satisfaction with both the program
and the CFLs. ADM's activities included developing survey questionnaires,
conducting survey interviews with 300 participants
and 125 nonparticipants, interviewing program
staff,
reviewing program records and other documents,
calculating annualized demand-reduction and
energy-saving impacts, and preparing an Evaluation
Report. |
| Prime
Power Pilot Program Evaluation |
This
project had two parts.
The first was to conduct an impact evaluation
of the NYSE-STAR Home component of
Long Island Lighting Company's Residential
New Construction Program. This work involved conducting a telephone survey of about 300
residential customers and home builders (both
participants and nonparticipants), and collecting
detailed data on-site for 18 houses (6 NYSE
STAR homes, 6 participants in the other components
of the New Construction Program, and 6 nonparticipant
homes).
Annual fuel-use in the homes were computed
using the DOE-2 computerized building energy
analysis program, calibrated to actual billing
records. The average annual fuel-uses for the
three groups were then compared.
The other part of the project was to
perform an evaluation of weatherization measures
in existing single-family homes that are heated
by natural gas.
This evaluation consisted of obtaining
detailed data on-site at 5 homes, performing
blower-door tests to measure air infiltration,
performing the weatherizations, repeating the
blower-door tests, and then using the DOE-2
program to estimate annual gas savings for each
home. |
| PG&E
Nonresidential Energy Management Services Evaluation |
For
Pacific
Gas and Electric, ADM conducted a study
of the air conditioner repair program being
operated by PG&E in the Fresno area.
Telephone interviews were conducted with
350 PG&E customers in the Fresno area to
determine their attitudes toward the program
and toward PG&E.
The study was conducted in two waves.
In the pre-wave, telephone interviews
were conducted with 200 PG&E customers,
divided equally between participants and nonparticipants
in the air conditioner study.
In the post-wave, telephone interviews
were conducted with 150 participants, using
a modified version of the questionnaire used
for the pre-wave interviews. |
