Cost-effectiveness evaluations compare energy efficiency's benefits and costs to judge whether to expand, retain, revise, or eliminate efficiency programs or specific measures. This presentation discusses the basics of cost-effectiveness assessments for utility customer-funded efficiency portfolios as well as issues and options that should be considered when assessing cost-effectiveness, selecting which test(s) to use, and quantifying the components of tests (e.g., non-energy impacts, measure costs).

This presentation covers the current pilot project testing M&V2.0 as an evaluation tool facilitated by Connecticut Department of Energy and Environmental Protection (CT DEEP). Speakers on this panel presented examples of how whole building modeling is currently being used for M&V now and its potential future applications. Speakers also discussed benchmarking, data access and other protocols, and how experience with efficiency programs teach us so we can build upon the current experience.
This report provides a comprehensive review and analysis of home energy upgrade programs with proven track records, focusing on those with robustly verified savings and constituting good examples for replication. This meta-analysis describes program models and implementation strategies for direct install upgrades; heating, HVAC replacement and early retirement; and comprehensive, whole-home upgrades.
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 guide supports the development, maintenance, and use of accurate and reliable Technical Reference Manuals (TRMs). TRMs provide information to estimate the energy and demand savings of end-use energy efficiency measures associated with utility customer-funded efficiency programs. This guide describes existing TRMs in the United States and provides recommendations for TRM best practices. It also offers related background information on energy efficiency; evaluation, measurement, and verification; and TRM basics.
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 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.
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.
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.
This summary from a Better Buildings Residential Network peer exchange call focused on energy modeling in multifamily homes.
This summary from a Better Buildings Residential Network peer exchange call focused on the advantages and challenges of data tracking systems.
This summary from a Better Buildings Residential Network peer exchange call focused on evaluating and demonstrating the cost-effectiveness of energy upgrades to programs.
This summary from a Better Buildings Residential Network peer exchange call focused on how loan performance data is tracked and analyzed, and what the data shows.
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 peer exchange call summary focused on how to calculate and communicate program activities and results.
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 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 peer exchange call summary focused on effective program evaluation and incorporating changes into programs based off evaluation insight.
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 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 provides an overview of evaluation, measurement, and verification approaches used to estimate the load impacts and effectiveness of energy efficiency programs.
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.
