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.

Each ResStock fact sheet presents the potential for residential energy and utility bill savings for the state. The top ten energy savings home improvements are highlighted.

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 U.S. Department of Energy's (DOE) Building America research team, Advanced Residential Integrated Energy Solutions Collaborative (ARIES), worked with four public housing authorities (PHAs) to develop packages of energy-efficiency retrofit measures that PHAs can cost-effectively implement with their own staffs during the normal course of housing operations when units are refurbished between occupancies. More than 1 million public housing units supported by the U.S. Department of Housing and Urban Development (HUD) provide rental housing for eligible low-income families across the country, ranging from single-family houses to multifamily, high-rise apartments.

Energy efficiency is good for you--and for the air you breathe, the water you drink, and the community in which you live. This fact sheet shows how saving energy reduces air and water pollution and conserves natural resources, which in turn creates a healthier living environment for people everywhere. It includes the stories of a family in Pennsylvania and a hospital in Florida.

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.

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 study looks at evidence of capitalization of energy efficiency features in home prices using data from real estate multiple listing services (MLS) in three metropolitan areas: the Research Triangle region of North Carolina; Austin, Texas; and Portland, Oregon. These home listings include information on Energy Star certification and, in Portland and Austin, local green certifications. Our results suggest that Energy Star certification increases the sales prices of homes built between 1995 and 2006 but has no statistically significant effect on sales prices for newer homes.

Many states have adopted policies intended to overcome the barriers that limit the more efficient use of electricity. Yet because such efforts have not addressed the lack of consumer information and motivation to improve efficiency, many opportunities for energy efficiency remain untapped. To help address that problem, states, utilities, and other energy efficiency service providers have begun to develop new approaches to informing and motivating customers based on behavioral economics and psychology research. This report describes three broad strategies that states can use to engage consumers' participation in energy efficiency programs: provide direct consumer information and feedback on energy use, influence social norms; and match messages and messengers to target audiences. Recommendations for actions that governors can take within the context of each of those three strategies are provided.

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.

This study provides statistically significant analysis that ENERGY STAR qualified new homes sell faster (i.e., fewer days on the market) and for higher prices (i.e., sell for higher prices, or sell for a greater percentage of the listing price, or have a higher price per square foot) than comparable nonqualified homes, providing valuable evidence that there is a market advantage for ENERGY STAR qualified homes.

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 considers consumers' perspectives on policy and regulatory issues associated with the administration of energy efficiency investments funded by ratepayers of electric and natural gas utilities.

This report summarizes the scale and economic value of energy efficiency for reducing carbon emissions and discusses barriers to achieving the potential for cost-effective energy efficiency.
