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.

Reviews and summarize energy efficiency financing models and strategies. Models are analyzed according to funding sources, program structures, limits to scale, repayment vehicles, and project risks. Strategies consider applicable building sectors, models, levels of establishment, growth potential, advantages, and disadvantages.

This report describes different approaches to energy efficiency finance taken by utilities.
