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 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.
This guide supports the development, maintenance, and use of accurate and reliable Technical Reference Manuals (TRMs).

Energy efficiency program evaluation is increasingly important as utilities implement programs to meet regulatory requirements, such as energy efficiency portfolio standards. While utilities need internal staff to oversee evaluation activities, most evaluations are actually conducted by outside consultants. Thus, utility staff require a sufficient understanding of the evaluation process to plan program evaluation activities as well as to manage internal stakeholders and evaluation contractors. This guide is intended to help prepare utility staff to accomplish these tasks.
This paper explores ways in which program administrators are using social norms to spur behavior change and, as a result, curb energy use. In recent years, home energy reports (HER) programs have applied the concept of social norms to the energy efficiency context. These feedback programs inform customers of how their energy consumption compares to their neighbors' and provide other information about their usage, with the goal of enticing customers to change their energy use behavior to improve their relative neighborhood ranking.

This document provides guidance on how policymakers, utilities, and regulators should approach whole-building data access to maintain the confidentiality of utility customers.
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.
The benefits of energy efficiency extend beyond energy savings. Homes, commercial buildings, and industrial facilities gain comfort, health, and safety benefits from energy efficiency programs. Additional benefits for businesses include savings on maintenance, materials, and the costs of regulatory compliance. On the supply side, electric utilities enjoy reduced system costs. Focusing on the residential, business, and utility sectors, this report examines each of these multiple benefits, their role in program marketing, and current best practices for including them in cost-effectiveness testing.
New advanced Information and Communications Technologies (ICT) are pouring into the marketplace and are stimulating new thinking and a shift in the energy efficiency EM&V paradigm. These emerging technologies, including advanced data collection and analytic tools, are purported to provide timely analytics on program results and efficacy. This report reviews how new data analytic tools serve to help identify savings opportunities and engaging customers in programs like never before, and explores the potential for advanced data collection (e.g. AMI, smart meters) and data analytics to improve and streamline the evaluation process.
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.
Among the many benefits ascribed to energy efficiency is the fact that it can help create jobs. Although this is often used to motivate investments in efficiency programs, verifying job creation benefits is more complicated than it might seem at first. This paper identifies some of the issues that contribute to a lack of consistency in attempts to verify efficiency-related job creation. It then proposes an analytically rigorous and tractable framework for program evaluators to use in future assessments.
The report presents an analysis of the market performance of third-party certified sustainable residential properties in the Portland and Seattle metropolitan areas.

This paper presents the results of a comprehensive study of the energy-related needs of California’s low-income population. This study was commissioned to direct future policy regarding the various low-income energy programs offered in the state. These programs include the California Alternate Rate for Energy (CARE) Program, which provides a rate discount to qualified low-income customers, and the Low-Income Energy Efficiency (LIEE) Program, which installs weatherization and energy efficiency measures in qualified dwellings at no charge.
This paper describes existing barriers to integrating energy efficiency data into real estate markets, and illustrates recent efforts to address them. National cross-industry collaborations have resulted in standard data collection and transfer tools that allow home performance data to be shared across industries. Real estate markets in some regions have begun including these data into multiple listing services (MLS), making them visible during real estate transactions.
This study examines actual loan performance data obtained from CoreLogic, the lending industry’s leading source of such data. To assess whether residential energy efficiency is associated with lower default and prepayment risks, a national sample of about 71,000 ENERGY STAR and non-ENERGY STAR-rated single-family home mortgages was carefully constructed, accounting for loan, household, and neighborhood characteristics. The study finds that default risks are on average 32 percent lower in energy-efficient homes, controlling for other loan determinants.
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.
