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.

This report reviews Ouachita Electric Cooperative's transition to its HELP PAYS® tariffed on-bill investment program. This analysis uses data for the first nine months of the program launched in 2016. Some of those benefits are being validated immediately by the market response in the service area compared to the same period of the prior year with HELP, the on-bill financing program that HELP PAYS replaced.

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 explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.

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.

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.

Residential air-source heat pumps (ASHP) are a heating and air-conditioning technology that use electricity to provide a combination of space heating and cooling to homes. A new generation of ASHPs has come to market over the past five years. This report evaluates the key market barriers as well as potential opportunities to leverage. Based on an assessment of the regional ASHP market, it is clear that while ASHPs have established a viable and growing market, there remains a significant opportunity to further accelerate adoption of the technology and in the process achieve energy and cost savings to the Northeast and Mid-Atlantic region.

This guide for states highlights energy efficiency as a least-cost strategy to meet air pollution reduction and other policy objectives, including energy affordability and reliability. It presents established policy and program “pathways” to advance demand-side energy efficiency.

This summary from a Better Buildings Residential Network peer exchange call focused on innovative financing approaches programs are using to support residential energy efficiency.

Energy efficiency collaboratives vary greatly and are typically designed for a specific jurisdiction, making them hard to compare side by side. This guide seeks to highlight a few common elements and draw conclusions on the overall effectiveness of specific characteristics of collaboratives. This guide defines and examines four different types of collaboratives in terms of their origin, scope, decision-making method, membership, duration, available resources, and how they interact with and influence their respective commissions.

This presentation covers the New York On-Bill recovery financing, Home Energy Lending Program's (H.E.L.P.) loan program, and California energy efficiency financing products.

This study documents the market valuation associated with the predominant green and energy efficiency home certifications used in the Northwest. Regional markets with a track record of including green building and energy efficiency information in MLS databases have lacked a recent, thorough, locally relevant analysis of the potential value of “higher performing” homes in current market conditions. Real property appraisers require a reliable, localized, granular analysis they can use in their home valuation calculations. The analysis contained in this report addresses this identified market need.

This guide is designed to serve as a "how-to" reference for island communities (or small, similarly sized, more isolated communities) that want to develop and implement a residential energy-efficiency and conservation program. The purpose of this guide is to help communities chart a course for successful program development based on the lessons learned during implementation and operation of RePower Bainbridge, an energy-efficiency program on Bainbridge Island, Washington.
