This report builds and expands off of previous research by collecting and evaluating data from 800 Illinois Home Performance (IHP) retrofits. This study investigates homeowner measure package choices in the Illinois Home Performance with ENERGY STAR® (IHP) program compared to cost-optimal choices determined through Building Energy Optimization (BEopt™) modeling software.

This report documents findings and recommendations from an impact evaluation of the California Energy Commission’s California Comprehensive Residential Retrofit program, a statewide energy upgrade program funded by the American Recovery and Reinvestment Act of 2009. The program funded local and regional subrecipients to develop and test initiatives aimed at transforming the residential energy upgrade market and building an infrastructure for whole-building energy upgrades. These local and regional governments collaborated with California’s major utilities to jointly conduct the statewide Energy Upgrade California program.

The Multi-State Residential Retrofit Project is a residential energy-efficiency pilot program, funded by a competitive U.S. State Energy Program (SEP) award through the U.S. Department of Energy. The Multi-State Project operates in four states: Alabama, Massachusetts, Virginia, and Washington. During the course of this three-year process evaluation, Cadmus worked closely with NASEO and the four states to collect information about the programs from many perspectives, including: State Energy Office staff, program implementers, homeowners, auditors/contractors, real estate professionals, appraisers, lenders, and utility staff. This report discusses: the project’s context; its goals; the evaluation approach and methods; cross-cutting evaluation results; and results specific to each of the four states.

This report demonstrates the results achieved to date by the Southeast Energy Efficiency Alliance. It highlights the experiences of Consortium programs, their successes driving further investments in energy efficiency improvements, and the challenges that hindered their progress. It also details the infrastructure, resources, and opportunities that support the deployment of energy efficiency programming, and the approaches that the Consortium has found best suited to the region.

This report presents impact evaluation results for the Energy Savers program for large multi-family buildings. The Energy Savers program is run by CNT Energy and Community Investment Corporation. Initiated in January 2008 and now in its fifth year of existence, the Energy Savers program involves a variety of services to promote energy efficiency improvements for multi-family residential buildings of 5-50 units in the affordable housing market segment.

This interim evaluation report examines the design, delivery, and market effects of each of the Southeast Energy Efficiency Alliance's (SEEA) thirteen sub-grantee programs and identifies opportunities to increase each program's success, and quantifies and verifies the energy savings achieved through the programs' funded home energy improvements and the cost-effectiveness of those savings.
