This paper examines the current state of energy efficiency financing, highlighting segments of strength such as cars, green buildings, and energy service companies, and offering areas that are underserved, including residential low-income and moderate-income households and multifamily housing.

This paper analyzes Bank of America's $55 million initiative to provide low-cost funding and grant support to advance energy efficiency investment in low- to moderate-income communities. The funding supported community development financial institutions (CDFIs) in developing and enhancing efficiency programs for residential, commercial, and multifamily buildings. We report on loan performance, energy savings, and the degree to which the savings offset the cost of the energy efficiency investment.

This report provides an overview of credit enhancements available, such as loan loss reserves, loan guarantees, debt service reserve funds, and subordinated capital. It also discusses key issues related to credit enhancement, examples of how others have successfully implemented credit enhancements as part of their energy efficiency financing programs, and additional information on existing resources that provide further information on credit enhancement design and implementation.

Outlines five public-private financing mechanism options for energy efficiency upgrades programs, including on-bill financing, PACE financing, and loan loss reserve funds.
