This report updates ACEEE's 2013 assessment of multifamily energy efficiency programs in US metropolitan areas with the most multifamily households. Using housing, policy, and utility-sector data from 2014 and 2015, this report documents how these programs have changed in the context of dynamic housing markets and statewide policy environments. The report also offers an analysis of the number, spending, offerings, and targeted participants of current programs and their potential for further expansion.

The NorthernSTAR and U.S. Department of Energy Building America Program partnership investigated a new model to deploy building science-guided performance solutions to homeowners. This research explored three aspects to market delivery:
1. Understand the homeowner's motivations regarding investing in building science-based performance upgrades.
2. Determine a rapidly scalable approach to engage large numbers of homeowners directly through existing customer networks.
3. Access a business model that will manage all aspects of the contractor-homeowner performance professional interface to ensure good upgrade decisions throughout time.

This report details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.

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.

The report, based on U.S. Bureau of Labor Statistics data and a survey of tens of thousands of businesses across the country, provides detailed breakdowns of clean energy jobs not available previously, and it was developed and released in connection with a major U.S. Department of Energy study of all energy jobs in America.

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

This report, informed by leading research and real-world examples, highlights practical online and in-person tactics that contractors can use to promote social interaction and social comparison among homeowners to make energy upgrades a "must-have" in U.S. homes.

This report provides information and tools for policymakers, regulators, utilities, shared renewable energy developers, program administrators and others to support the adoption and implementation of shared renewables programs specifically designed to provide tangible benefits to low income and moderate income individuals and households.

This report lays the groundwork for a dialogue to explore regulatory and policy mechanisms for ensuring that efficiency financing initiatives provide value for society and protection for consumers. Through case studies of Connecticut, New York, Massachusetts, California, and Maryland, it explores emerging issues that jurisdictions will need to tackle when considering an increased reliance on financing.

This webcast covers a report that is a comparative analysis of utility-run behavior programs, which lays the groundwork for further program development by developing a classification scheme, or taxonomy, that sorts programs into discrete categories.

The California investor-owned utilities -- Pacific Gas and Electric (PG&E), Southern California Edison (SCE), Southern California Gas (SoCalGas), and San Diego Gas & Electric (SDG&E), referred to collectively as the IOUs or Joint Utilities -- are designing seven energy efficiency financing pilot programs at the California Public Utilities Commission’s (CPUC's) direction. To help inform the pilot design process and subsequent evaluation efforts, this report summarizes a comprehensive review of 15 existing financing programs representing noteworthy program models across the United States and around the globe.

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.

This webcast provided an overview of on-bill financing programs, and presented three case studies: Manitoba Hydro, New York State Energy Research and Development Authority, and Pacific Gas & Electric (California).

This report provides an overview of the current state of on-bill programs and provides actionable insights on key program design considerations for on-bill lending programs.

This webcast discusses the background for U.S. Department of Energy’s Smart Grid Investment Grant (SGIG) consumer behavior study effort; the various utilities who are participating and what they each plan to include their respective studies; the quantitative results and qualitative lessons learned thus far from these studies; and the types of research will be undertaken by LBNL over the next several years.

Study examining actual loan performance data to assess whether residential energy efficiency is associated with lower default and prepayment risks. Results show that default risks are on average 32 percent lower in energy-efficient homes, controlling for other loan determinants.

The objective of this document is to help state and local governments understand the role of program administrators (PAs) and assist them in developing successful partnerships with utility and other energy efficiency PAs. The majority of this paper presents information on partnering and leveraging current energy efficiency activities. However, it also includes information for governments in areas without active PAs, as well as an appendix with a case study describing how state and local governments can fill gaps and administer programs in the absence of a PA.

This guide shows HVAC contractors how to get started in the home improvement market. It explains the approach of treating a house like a system and provides step-by-step instructions on setting up a home performance contracting business.

This webcast (Part III of a three-part series) covers how to choose and implement financing options that meet local needs.

This paper establishes the size of the potential retrofit market in the United States, and examines the emergence of new financing models that offer the promise of overcoming historical barriers to energy efficiency.

This U.S. Environmental Protection Agency resource is intended to help state and local governments design finance programs for their jurisdiction. It describes financing program options, key components of these programs, and factors to consider as they make decisions about getting started or updating their programs.

This report provides state and local policymakers with information on successful approaches to the design and implementation of residential efficiency programs for households ineligible for low-income programs.
