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.

This industry survey incorporates raw data collected from local, state and national energy efficiency, green and high performance certification and verification programs, builders and developers, home energy raters and many others to compile an updated database of units built or retrofitted in North Carolina since approximately 2007. 

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.

The Guide to Action provides in-depth information about over a dozen policies and programs that states are using to meet their energy, environmental, and economic objectives with energy efficiency, renewable energy, and combined heat and power. Each policy description is based on states’ experiences in designing and implementing policies, as documented in existing literature and shared through peer-exchange opportunities provided to states by EPA’s State Climate and Energy Program.

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.

Example Request for Proposal (RFP) to provide The City of Greensboro with an estimate for the work required to create a Business Process Management Information Technology Tool (BPM IT Tool) for a municipal energy efficiency project.

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 summarizes research assessing national and regional residential behavior-based energy efficiency (BBEE) programs and activities to identify best practices. The report emphasizes that a basic foundation for behavior change is providing energy consumers with feedback on their energy consumption, with customer engagement strategies and tactics employed to get customers to take action and drive greater levels of energy savings.

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 guide provides background on the home improvement market in the U.S. and Canada and end users and systems in existing homes, as well as a description of energy efficiency program approaches and strategies.

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.
