Selected Projects

Below is a small sample Evergreen Economics project experience.
(Note that Evergreen staff managed some of these projects while they were employed at other companies.)

Evaluation of Hawaii’s Energy Efficiency Program Portfolio. For the Hawaii PUC, Evergreen is leading a team to evaluate Hawaii’s energy efficiency programs covering the residential and non-residential sectors. This evaluation will include impact, process, and market assessment research. Data collection and analysis tasks include participant and nonparticipant phone surveys, engineering analysis, on-site verifications, billing regressions, and in-depth interviews with trade allies and other market actors.

Independent Evaluator for the State of Ohio.
For the Public Utilities Commission of Ohio (PUCO), Evergreen is working as the Independent Evaluator to assist PUCO with developing rigorous estimates of energy and demand impacts for the Ohio utility DSM programs. The Evergreen team is reviewing the deemed savings values, conducting site visits to verify equipment installations, conducting participant surveys and baseline nonparticipant surveys, and verifying all the impact evaluation work conducted by the utility evaluation teams. Where needed, we will be conducting our own independent analysis of program impacts where there are gaps in the utility evaluation efforts.

Estimating Embedded Energy Savings From Water Conservation Programs.
For the California Public Utilities Commission (CPUC), Evergreen staff managed the EM&V of 8 separate pilot programs targeting water conservation that are joint program efforts between the electric utilities and local water agencies in California. For each pilot, the amount of water savings achieved is measured, either from analyzing bills or installing meters at the end use sites. The information on end use water savings is combined with information on the water agencies that supply fresh water and treat the wastewater for each territory covered by the pilot program. The water savings and water agency data are used to estimate the amount of electricity is saved as a result of the reduced water consumption (embedded energy savings). The embedded energy savings estimates are being developed for specific measures for different water agencies and will be used to update the CPUC’s Embedded Energy Savings Calculator.

Impact Evaluation and Discrete Choice Modeling for Small Commercial Energy Conservation Programs.
For the CPUC, Evergreen staff (as subcontractors to Itron) assisted with the impact evaluation of multiple energy conservation programs that target the small commercial customer market sector. Tasks include assisting with developing the evaluation plan, developing sample methods, and creating models to estimate net realized energy impacts resulting from the programs. Modeling techniques include billing regression analysis and discrete choice models of customer equipment choices.

Impact Evaluation of Commercial Program Portfolio.
For Consumers Energy in Michigan, Evergreen is managing the multi-year impact evaluation component of Consumers’ portfolio of efficiency programs for commercial and industrial customers. Tasks include developing the sample design for on-site metering, verification inspections, and phone surveys. Modeling tasks include conducting billing regression models to determine realized savings from these programs. Evergreen is a subcontractor to EMI for this project and is contributing to the process evaluation and market effects/baseline research that are also being conducted as part of this multi-year evaluation.

Impact Evaluation of Residential and Commercial Efficiency Programs.
As a subcontractor to Tetra Tech, Evergreen is conducting the impact evaluation for the Black Hills Energy programs in Colorado and Iowa, with additional states and programs expected to be added in the future. The evaluation is multi-year and covers both the residential and non-residential programs in each state. Tasks include assisting with developing evaluation plans, writing survey instruments, reviewing deemed savings values, and using billing regression and discrete choice models to estimate gross and net program impacts. Conjoint analysis is also be used to collect additional market data on customer preferences for efficiency programs and energy efficient equipment options.

Impact Evaluation of a Low Income Energy Efficiency Program.
For the California PUC, Evergreen is evaluating California’s Statewide Low Income Energy Efficiency (LIEE) Program. This impact evaluation involves estimating the realized energy savings due to the LIEE program efforts in low income households throughout the state. Analysis tasks included on-site visits, participant and nonparticipant phone surveys, engineering analysis, and billing regression models to estimate realized energy savings from the installed measures.

Process Evaluation of a Residential Efficiency Program Portfolio.
For SDG&E, Evergreen staff headed a team to conduct process evaluations for 10 of SDG&E and SoCal Gas energy efficiency programs. Tasks included developing logic models, fielding phone surveys, conducting in-depth interviews in support of a process evaluation. In addition, Evergreen staff conducted a portfolio analysis to assess how well the group of programs fit within the broader energy efficiency program landscape within California as well as within the larger conservation program portfolio at SDG&E.

Process and Impact Evaluation of a Home Energy Efficiency Survey.
For Pacific Gas and Electric and Southern California Edison, Evergreen staff conducted evaluations of the Home Energy Efficiency Survey program (HEES). The HEES program is designed to provide customers a comprehensive home audit to identify ways they can conserve energy. Customers can take the survey online, by phone, or by mail. For the evaluation, Evergreen staff examined customer satisfaction with the survey and assess whether or not completing the audit survey actually resulted in any changes in behavior regarding energy consumption. This involved conducting an online survey of participants (for those that did the HEES online) and fielding a phone survey to customers that did the phone or mail-in version of the HEES. For Pacific Gas and Electric, this project also involved an impact evaluation where phone survey and historical billing data are combined with HEES recommendations to quantify energy savings that result from taking the HEES survey.

Evaluation of the ENERGY STAR Homes Northwest Program.
For the Northwest Energy Efficiency Alliance, Evergreen staff are evaluating the Energy Star Homes Northwest program that provides the Energy Star label for residential new construction. The program focuses on training builders to use high efficiency building components (lighting, heating/cooling, windows, duct testing) to meet the Energy Star standard. Evaluation efforts include tracking market penetration, surveying homebuyers on market drivers and barriers, process evaluation, and determining baseline builder practices so program progress can be tracked. The evaluation is also assisting in the cost effectiveness calculations and providing recommendations based on evaluation analysis for key impact and cost effectiveness parameters.

Evaluation of an ENERGY STAR Residential Lighting Program.
For the Northwest Energy Efficiency Alliance, Evergreen staff evaluated a program promoting residential compact fluorescent lighting (CFL). The program focuses on providing support to retailers for promoting CFL bulbs and fixtures and also incorporated the impacts of the BPA Coupon Campaign. Evaluation efforts include tracking sales, estimating market penetration, and determining how the program has influenced CFL sales over time as measured by multiple consumer surveys. Evaluation efforts have also focused on reviewing impact and cost effectiveness estimates and providing recommendations on how these estimates can be improved.

Logic Modeling and Program Theory for Conservation and Renewable Energy Programs.
For the New York State Energy Research and Development Authority (NYSERDA), Evergreen staff were on a team (with Research Into Action) that evaluated 41 programs contained in the New York Energy $mart Program. This multi-year evaluation focused on the program logic and theory underlying these programs. Activities included reviewing program documentation, developing logic models documenting current program activities, and evaluating how well the program logic compares with social science theory and experiences with similar programs in other regions.

Evaluation of 6 Local Government Partnership Programs.
For Pacific Gas and Electric, Evergreen staff evaluated the performance of 6 DSM programs being implemented as partnerships with local governments in California. Evaluation tasks include developing and verifying estimates of net energy impacts resulting from the program, estimating free ridership, surveying program participants, and conducting a process evaluation of the program delivery for each partnership.
