Efficiency Maine Trust Home Energy Savings Program Final Evaluation Report

Date Published: November 30, 2011     Document Type: Evaluation study type/report
Sectors: Evaluation, Program Evaluation, Research, Evaluation, & Behavior, Residential

This report presents the results of an impact evaluation of the Efficiency Maine Trust (Efficiency Maine or Trust) Home Energy Savings Program (HESP or Program), conducted by The Cadmus Group, Inc. (Cadmus). The HESP is a residential, whole-house, energy-efficiency program that targets existing homes in Maine, and is available to any residence in Maine that is heated during the winter (regardless of occupants’ income levels). The evaluation addressed the following research objectives:

Determine energy savings;
Evaluate the cost-effectiveness and job creation potential (due to funding from theAmerican Recovery and Reinvestment Act (ARRA));
Compute carbon emissions reductions and environmental impacts; and
Assess customer satisfaction.

The goal of this report is to present a summary of the findings and results from the Impact and Process Evaluation of the energy efficiency and demand response programs offered by ComEd in Plan Year 2, which ran from June 1, 2009 to May 31, 2010.

Energy Efficiency/ Demand Response Plan: Plan Year 2 (6/1/2009-5/31/2010) Evaluation Report: All Electric Single Family Home Energy Performance Tune-Up Program

Date Published: December 21, 2010     Document Type: Evaluation Study / Report, Report
Sectors: Research, Evaluation, & Behavior, Residential

The goal of this report is to present a summary of the findings and results from the evaluation of the Program Year 2 (PY2) All Electric Single Family Home Energy Performance Tune-Up Program. The objectives of the evaluation are to: (1) quantify net energy and peak demand savings impacts from the program during Program Year 2 (PY2); and (2) to determine key process-related program strengths and weaknesses and provide recommendations to improve the program.

Lessons Learned and Next Steps in Energy Efficiency Measurement and Attribution: Energy Savings, Net to Gross, Non-Energy Benefits, and Persistence of Energy Efficiency Behavior

Date Published: November 1, 2009     Document Type: Report, White paper
Sectors: Behavior, Research, Evaluation, & Behavior

This white paper examines four topics addressing evaluation, measurement, and attribution of direct and indirect effects to energy efficiency and behavioral programs:

  • Estimates of program savings (gross);
  • Net savings derivation through free ridership / net to gross analyses;
  • Indirect non-energy benefits / impacts (e.g., comfort, convenience, emissions, jobs); and
  • Persistence of savings.

Evaluation and attribution methods have reached a point that they must evolve in order to provide credible results for the next generation of programs. Two primary factors have complicated the methodologies that have been applied to energy efficiency programs:

  • Transition to more behavioral, outreach and other non-measure-based programs (education, advertising), making it especially hard to “count” impacts, and
  • Increased chatter in the marketplace, in which consumers may be influenced by any number of utility programs by the host/territorial utility (the “portfolio”) as well as influences from outside the territorial utility (national, neighboring programs, movies/media).
