This report is a guide to all customer-facing financing products—products offered by a lender directly to a borrower—used to pay for energy efficiency. Intended for state and local governments that are deciding whether to start a new program, tune up and existing program, or create a Green Bank, it provides information on the full range of financing product options for target participants, the tradeoffs of various products, and potential advantages and disadvantages for different types of customers.

This Guide is designed to help state and local policymakers to take full advantage of new policy developments by providing them with a comprehensive set of tools to support launching or accelerating residential energy efficiency programs. The Guide focuses on four categories of policies that have proven particularly effective in providing a framework within which residential energy efficiency programs can thrive: incentives and financing, making the value of energy efficiency visible in the real estate market, data access and standardization, and supporting utility system procurement of energy efficiency.

This study examined consumer awareness and opinions concerning the New Jersey Clean Energy Program (NJCEP). Research areas included New Jersey homeowners' awareness of NJCEP, an assessment of attitudes towards energy efficiency, the main benefits associated with energy efficiency, key drivers associated with purchasing energy efficient products, the best methods for increasing consumers awareness of NJCEP, and obstacles to implementing energy efficiency measures in the home.

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 evaluation and research plan sets out a proposed process for establishing and executing a detailed evaluation and research plan for New Jersey's Clean Energy Program.

This memo provides a review of the New Jersey Comfort Partners Energy Saving Protocols, recommends changes to the calculations and additional calculation protocols for measures not included, and calculates engineering estimates for those proposed energy savings formulas.

This paper explores ways in which program administrators are using social norms to spur behavior change and, as a result, curb energy use. In recent years, home energy reports (HER) programs have applied the concept of social norms to the energy efficiency context. These feedback programs inform customers of how their energy consumption compares to their neighbors' and provide other information about their usage, with the goal of enticing customers to change their energy use behavior to improve their relative neighborhood ranking.

This report presents results, recommendations, and case studies of energy efficiency financing programs.
