This paper is a baseline assessment of electric and natural gas energy efficiency programs that target low-income households in the largest metropolitan areas in the country. ACEEE surveyed over 70 electric and natural gas utilities on their 2015 low-income program spending, energy savings, customer participation, and best practices.

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.

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 webinar explored innovative measures Better Buildings Challenge partners have taken to improve water efficiency while reducing energy use. United Technologies Corporation discussed their impressive water reduction goals and best practices in managing water, while also focusing on energy management strategies at diverse manufacturing sites. The City of Atlanta discussed their new, high-efficiency pumping station and how the efforts of large-scale users to reduce water use can help the City reduce both water and energy use. InterContinental Hotels Group highlighted their worldwide water management program, which includes metering and tracking consumption and water efficiency strategies.

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.

The research described in this report holds great potential to significantly improve the process for including energy efficiency in developing and implementing federally funded multifamily rehabilitation projects through the USDA, the U.S. Housing and Urban Development (HUD) Low Income Housing Tax Credit, and other programs.

The multifamily sector can be hard to reach when it comes to energy efficiency programs. Besides being diverse and complex, the sector presents a unique set of challenges to efficiency investments. The result is that multifamily customers are often underserved by energy efficiency programs. Drawing on data requests and interviews with program administrators, this report summarizes the challenges to program participation and identifies best practices that programs can use to reach and retain large numbers of multifamily participants.

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 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.

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 guide identifies 12 best practices for policymakers, regulators, and program administrators to help building owners invest to increase the energy efficiency of multifamily affordable housing.
