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.
Utilities and regulators increasingly rely on behavior change programs as essential parts of their demand side management (DSM) portfolios. This report evaluates the effectiveness of currently available programs, focusing on programs that have been assessed for energy savings. This report focuses on behavior change programs that primarily rely on social-science-based strategies instead of traditional approaches such as incentives, rebates, pricing, or legal and policy strategies. The objective is to help program administrators choose effective behavior change programs for their specific purposes.
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 from the New York State Energy Research and Development Authority (NYSERDA) details the range of behavior change strategies in the existing portfolio and identifies strategic opportunities in the area of behavior change.
As part of its Smart Grid Investment Grant, Minnesota Power conducted a Consumer Behavior Study Plan (CBSP) designed to answer research questions about residential customers' interest in, use of, and benefits derived from higher resolution feedback on electricity consumption (such as usage data for each individual day or hour). The study also explored the customer experience with the tools that provide this information. These questions are of interest because the advanced metering infrastructure associated with a smart grid enables higher resolution usage information for utility customers, which has the potential to better inform them about their energy consumption and help them refine their usage choices. The CBSP began in the spring of 2012 and was implemented in the Duluth/Hermantown area of Minnesota.
This paper explores the drivers of energy use behaviors and the behavior‐based programs adopted by utilities charged with reducing the energy consumption of their residential and small commercial customers. It also presents researchable recommendations on how utilities can improve the effectiveness of behavior‐based energy programs.
A variety of new feedback initiatives, including real-time web-based or in-home feedback devices and enhanced billing approaches, are making energy resources visible to residential consumers throughout the United States. These initiatives are opening the door to potential energy savings that, on average, have reduced individual household electricity consumption 4 to 12%. In so doing, feedback is proving a critical first step in engaging and empowering consumers to thoughtfully manage their energy use.

The report also offers an analysis of the number, spending, offerings, and targeted participants of current programs and their potential for further expansion.
Research reveals a whole range of unmet housing-related desires in America -- gaps between what Americans have and what they say they need or want. The Demand Institute surveyed more than 10,000 households about their current living situation and what’s important to them in a home. The survey represents all U.S. households: renters and owners; movers and non-movers; young and old and finds that unsatisfied needs and desires cut across the entire population.
This study focused on barriers to, and opportunities for, solar photovoltaic energy generation; opportunities for, access to other renewable energy by low-income customers; contracting opportunities for local small businesses in disadvantaged communities; low-income customers to energy efficiency and weatherization investments, including those in disadvantaged communities. It also provides recommendations on how to increase access to energy efficiency and weatherization investments to low-income customers.
Residential air-source heat pumps (ASHP) are a heating and air-conditioning technology that use electricity to provide a combination of space heating and cooling to homes. A new generation of ASHPs has come to market over the past five years. This report evaluates the key market barriers as well as potential opportunities to leverage. Based on an assessment of the regional ASHP market, it is clear that while ASHPs have established a viable and growing market, there remains a significant opportunity to further accelerate adoption of the technology and in the process achieve energy and cost savings to the Northeast and Mid-Atlantic region.
This technical brief presents trends in the cost of saved electricity for energy efficiency programs between 2009 and 2013. For this report, LBNL collected and analyzed more than 5,400 program years of data collected in 36 states from 78 administrators of programs funded by customers of investor-owned utilities. These administrators provide efficiency programs to customers of investor-owned utilities that serve about half of total U.S. electricity load.
Behavioral change programs are not necessarily a separate category of efficiency efforts; rather, behavioral approaches can be effectively integrated into all programs in residential, commercial, or industrial settings. As increased connectivity within homes and businesses expands opportunities to provide energy information, the role of behavior will likely become even more prominent. Consortium for Energy Efficiency, Inc. (CEE) provides this webpage dedicated to behavior change resources.
Research traditions across the social sciences have explored the drivers of individual behavior change and proposed different models of decision making. In this paper, four diverse perspectives are reviewed: conventional and behavioral economics, technology adoption theory and attitude-based decision making, social and environmental psychology, and sociology. This paper concludes with how to develop a more integrated approach to both behavioral change research and intervention design in a residential energy context.
To help inform and prompt discussion across a range of audiences on the health co-benefits from residential EE investments, this paper reviews research studies of residential EE and related ventilation upgrades, discusses ways that programs have monetized occupant health co-benefits, and highlights innovative programs that combine EE and health-focused home repairs. The paper concludes with identifying research gaps and strategies to help advance such work.
This report examines the history of pay-for-performance (P4P) energy efficiency approaches. As the report describes, there is a diverse spectrum of pay-for-performance programs but, at the most basic level, these programs track and reward energy savings as they occur, usually by examining data from a building's energy meters -- as opposed to the more common approach of estimating savings in advance of installation and offering upfront rebates or incentives in a lump-sum payment. The report finds that P4P has some important opportunities for increasing energy savings, but also key limitations that will need to be better understood through piloting and experimentation.
This report explains the psychology of individual energy efficiency actions, and how large scale behavior change programs can use this research to reduce greenhouse gas emissions.
This report explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.
This literature review describes what is currently known about the occupant health benefits resulting from residential energy efficiency or work that is consistent with home performance upgrades. Of particular interest are the occupant health impacts associated with work typically conducted by the home performance industry, such as: air sealing and insulation; properly-sized, selected, matched, and installed energy efficient heating, ventilation, and air conditioning (HVAC) systems; identification and correction of moisture problems; proper whole house and room ventilation; lighting; and additional services including the replacement of appliances; measurement and installation of whole house and room air filtration systems (e.g., air purifiers); and basic pest exclusion. The intent of this literature review is to examine research that assessed work that would not be expected to harm residents or the workers.
This report was developed to help inform national stakeholders about the strategies that have been used to achieve deep energy savings in the multifamily housing sector through energy efficiency upgrades. These strategies could be used as models in areas where utility program administrators and policymakers seek to achieve deep energy savings in the multifamily building stock for the purposes of reducing energy costs, creating comfortable and healthy homes, meeting regulatory requirements, or reducing the environmental impacts of energy consumption. This report includes a national multifamily market characterization, barriers and opportunities for program and policy efforts, and eight exemplary case studies from across the country.

This report, informed by leading research and real-world examples, highlights practical online and in-person tactics that contractors can use to promote social interaction and social comparison among homeowners to make energy upgrades a "must-have" in U.S. homes.
This paper describes a wide variety of behavior change insights potentially applicable to the energy efficiency program context, provides examples of efficiency programs that have applied these insights, and explores some untapped opportunities to achieve energy savings through behavior change.
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.
Over the past 30 years, program administrators have concentrated on investment behavior change -- that is getting their customers to install things like insulation and lighting systems using various behavior change tools such as marketing, education, rebates, and technical assistance to support the investment behavior change. Today, as program administrators move to expand the range of behavior change strategies in their portfolios, it is often difficult to know where to begin. The New York State Energy Research and Development Authority (NYSERDA) began by detailing the range of behavior change strategies and identifying strategic opportunities.
The purpose of this report is to demonstrate the potential for HEMS as an evolving avenue to deeper residential energy savings, and it explains, in detail, the variations and characteristics of HEMS; what the market is and who the major market players are; what the major barriers to implementation look like; and finally, it attempts to outline potential program solutions with HEMS at the core of the strategy.
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.
This document provides guidance on how policymakers, utilities, and regulators should approach whole-building data access to maintain the confidentiality of utility customers.
NEEP has been tracking the residential lighting market for several years and has provided analysis in many reports. As the transformation of this complex market gains traction, we find the conversation and need for new information narrowing to one key topic: LEDs. While CFLs continue to play a role in residences and amongst Northeast and Mid-Atlantic program administrators, the LED has transitioned into the starring role of the residential lighting show.
This report details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.
This report provides information and tools for policymakers, regulators, utilities, shared renewable energy developers, program administrators and others to support the adoption and implementation of shared renewables programs specifically designed to provide tangible benefits to low income and moderate income individuals and households.
This guide is designed to help state and local governments reduce carbon emissions by connecting them with EPA programs that can help them expand or develop their own energy efficiency and renewable energy initiatives in ways that benefit low-income communities. The guide can also be used by low-income community leaders and stakeholder groups to better understand how they might participate in and take advantage of EPA initiatives to help their communities save energy.
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.
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.
The NorthernSTAR and U.S. Department of Energy Building America Program partnership investigated a new model to deploy building science-guided performance solutions to homeowners. This research explored three aspects to market delivery:
1. Understand the homeowner's motivations regarding investing in building science-based performance upgrades.
2. Determine a rapidly scalable approach to engage large numbers of homeowners directly through existing customer networks.
3. Access a business model that will manage all aspects of the contractor-homeowner performance professional interface to ensure good upgrade decisions throughout time.
Energy efficiency savings have grown substantially in the past ten years, and national leaders in program administration have emerged as savings levels have increased. This report reviews annual program performance for 14 leading energy efficiency program administrators, with a focus on costs, electricity savings, cost effectiveness, and portfolio design.
Several recent studies purport to show that particular energy efficiency programs and policies do not work or are too expensive. This short paper is written for people who are not evaluation experts and are trying to understand what conclusions they can take from these studies. We examine many of these papers and find that while they do have some useful findings, they often include a variety of unreasonable assumptions or outright mistakes that undermine their conclusions. Based on this review, we offer several recommendations on ways we can constructively move forward.
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.
Through field-testing and analysis, this project evaluated whole-building approaches and estimated the relative contributions of select technologies toward reducing energy use related to space conditioning in new manufactured homes. Three lab houses of varying designs were built and tested side-by-side under controlled conditions in Russellville, Alabama. The tests provided a valuable indicator of how changes in the construction of manufactured homes can contribute to significant reductions in energy use.
Building on the strategy of creating a sustainable workplace, many companies have been focusing their efforts on developing a sustainable workforce.

This white paper from Lawrence Berkeley National Laboratory describes the benefits and costs of energy advisors, and describes how residential energy efficiency programs have made use of them in their program design.
EPA released the updated State and Local Guide to U.S. EPA Climate and Energy Program Resources, a guide designed for state and local government staff that describes EPA programs and resources that can help them develop or expand their own energy efficiency and renewable energy initiatives or meet regulatory requirements.
This study documents the market valuation associated with the predominant green and energy efficiency home certifications used in the Northwest. Regional markets with a track record of including green building and energy efficiency information in MLS databases have lacked a recent, thorough, locally relevant analysis of the potential value of “higher performing” homes in current market conditions. Real property appraisers require a reliable, localized, granular analysis they can use in their home valuation calculations. The analysis contained in this report addresses this identified market need.
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.
Real estate professionals are increasingly aware that today’s homebuyers consider heating and cooling costs, efficient appliances, and efficient lighting to be important factors in home purchase decisions. Residential energy efficiency and real estate stakeholders, however, agree that the home resale process frequently fails to account for the value of high-performance home features. If investments in energy efficiency were more accurately reflected in home resale prices, homeowners could have greater confidence that these investments would be recouped at resale, and they might make more investments in 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.
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 lack of documented value of retrofit measures is a barrier to many homeowners doing upgrades - as most appraisals do not include energy improvements in their comparables, and the home’s future sale can prevent the homeowner from earning a return on their investment via lower energy costs. Once the industry develops a process for valuing the energy improvements, it can unlock the significant potential for retrofit work through market pricing signals (energy efficient homes are worth more) and enhanced access to capital for those purchasing a more efficient home (energy efficient homes improve borrowers’ cashflow because they cost less to operate).
The report presents an analysis of the market performance of third-party certified sustainable residential properties in the Portland and Seattle metropolitan areas. In each location, a sample of third-party certified homes was selected and comparable homes were found. The author documents that certified homes in the Seattle metro area sold at a price premium of 9.6% when compared to noncertified counterparts.
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.
The purpose of this study is to furnish comprehensive information on ratepayer-funded low-income energy programs. This study includes information on and analysis of the energy needs of low-income households, the legal and regulatory framework supporting ratepayer-funded programs, program design options, and the findings from evaluations of program effectiveness.
This white paper provides energy efficiency program sponsors and other stakeholders in the home performance industry with methods to document efficiency improvements and incorporate them into the real estate value chain. Making information about energy efficiency improvements visible to home buyers and others involved in a home sale transaction will play a crucial role in ensuring that improvements are fairly valued at the time an existing home is sold.
This paper explores the State Energy Efficient Appliance Rebate Program (SEEARP) designs and delivery methods used, and provides lessons learned about specific program models and best practices for states, utilities, and energy efficiency organizations to use in designing rebate programs.
This report is targeted at both policymakers and program administrators who are less familiar with secondary markets and their significance in the energy efficiency context, as well as those that are more familiar with these concepts and may be actively considering secondary market strategies. It covers how efficient access to capital from secondary markets -- reselling energy loans to investors to replenish program funds -- is being advanced as an important enabler of the energy efficiency industry “at scale.”
The objective of this Guide, in part, is to serve as a resource to support municipal electric utilities meeting electricity savings goals. This Guide serves as a resource to not only increase the understanding of best practices utilized by successful energy efficiency programs across the country, but also a plan to support MOUs implementing energy efficiency programs that will ultimately result in energy and electric bill savings for their customers. To support MOUs with the implementation of their own energy efficiency programs, this Guide leverages the lessons learned from energy efficiency programs operating across the country.
