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 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 report looks into residential lighting savings assumptions found in Technical Reference Manuals (TRMs) throughout the Northeast and Mid-Atlantic regions to understand what values were being used for key metrics such as hours of use, delta watt, and measure life.  It provides the opportunity to view completed Standardized Methods Forms to compare evaluation methodology and results.

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.

A number of states are beginning to recognize Demand Reduction Induced Price Effects (DRIPE) as a real, quantifiable benefit of energy efficiency and demand response programs. DRIPE is a measurement of the value of demand reductions in terms of the decrease in wholesale energy prices, resulting in lower total expenditures on electricity or natural gas across a given grid. This paper reviews the existing knowledge and experience from select U.S. states regarding DRIPE (including New York and Ohio), and the potential for expanded application of the concept of DRIPE by regulators.

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.

This report provides information on how access to energy use data can help local governments create policies for benchmarking and disclosing building energy performance for public and private sector buildings.

This report provides information on how supporting access to building benchmarking data can help utilities increase efficiency and drive down energy demand.

This report provides information on how energy use data access can help state governments lead by example through benchmarking and disclosing results and implement benchmarking policies for the private sector.

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 report identifies issues associated with developing a national evaluation, measurement, and verification (EM&V) standard for end-use, non-transportation, energy efficiency activities.

This report provides an overview of residential customer information and behavior efficiency programs, and identifies key challenges to and solutions for increasing the penetration of these programs nationwide.

This report presents the results of a scoping study to assess the need for national databases that can support best practices in energy efficiency program evaluation, measurement, and verification (EM&V).

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

This report provides an overview of evaluation, measurement, and verification approaches used to estimate the load impacts and effectiveness of energy efficiency programs.

This report describes the effects of utility spending on efficiency programs, how those effects could constitute barriers to investment in energy efficiency, and how policy mechanisms can reduce these barriers.
