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 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 summary from a Better Buildings Residential Network peer exchange call focused on how energy efficiency could be used to achieve other goals. It features speakers from the City of Orlando and Seattle City Light.

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.

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 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.

Quick summaries of strategies various programs have used to improve the efficiency of delivering efficiency.

This summary from a Better Buildings Residential Network peer exchange call focused on the challenges, strategies and advantages of  operating as a prime contractor.

Presentation that provides insights from a utility executive on how energy efficiency programs can effectively partner with utilities.

This webcast reviews the SEE Action report that describes how utility planning processes that allow demand-side resources to compete with supply-side resources can promote cost-effective energy efficiency.

This report explores the best practices that utilities should undertake in the development and implementation of energy efficiency programs. The report calculates the impact that investing in energy efficiency will have on jobs, household income, and state and regional economies, along with the other public health benefits such as reducing pollution.

This peer exchange call summary focused on best practices, entry points, strategies and challenges of program integration and participation in utility planning efforts.

Presentation on the SustainableWorks non-profit general contractor model for supporting energy upgrades in Washington state and lessons learned for implementing a whole house approach.

In this video interview segment, Yvonne Kraus of Conservation Services Group describes how program and utility partnerships can co-benefit each other.

The RePower programs in Washington State convened local community leaders, organizations, contractors, and program partners for a planning summit to consider the benefits and challenges of different business models for the post-grant period. Participants considered four models: non-profit organization, utility, county or city government, and private sector.

In this video interview segment, Will Ranes of RePower Kitsap discusses the importance of understanding your market, including being able to speak the language of utilities and other key players.

This report helps policymakers understand how electric and natural gas utilities can achieve greater efficiency by establishing numeric energy savings targets and goals for energy efficiency programs.

This report describes how utility planning processes that allow demand-side resources to compete with supply-side resources can promote cost-effective energy efficiency.

This report presents best practices for operating successful portfolio-level efficiency programs, including assessing efficiency potential, cost-effectiveness screening, and developing a portfolio of approaches.

This guide helps states and localities develop voluntary or mandatory programs that go well beyond minimum code requirements for new buildings. It addresses energy efficiency materials and resource conservation, water efficiency, indoor environmental quality, and site development and land use.

The purpose of this study is to furnish comprehensive information on ratepayer-funded low-income energy programs. This study includes information on and analysis of the energy needs of low-income households, the legal and regulatory framework supporting ratepayer-funded programs, program design options, and the findings from evaluations of program effectiveness.

This report provides comprehensive information on state, federal, local, and utility incentives and policies that are in place to support renewable energy and energy efficiency.
