This paper examines criteria for a comparative assessment of multiple financing programs for energy efficiency, developed through a statewide public process in California.

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 presents findings from an impact evaluation of the Universal Audit Tool (UAT). UAT programs provide residential customers with advice on energy efficiency, insight into areas of high energy use, and tips and suggestions for saving both energy and money based on responses to an online survey regarding household appliances, occupancy, and other dwelling characteristics.

This report is a guide to all customer-facing financing products—products offered by a lender directly to a borrower—used to pay for energy efficiency. Intended for state and local governments that are deciding whether to start a new program, tune up and existing program, or create a Green Bank, it provides information on the full range of financing product options for target participants, the tradeoffs of various products, and potential advantages and disadvantages for different types of customers.

This paper examines the current state of energy efficiency financing, highlighting segments of strength such as cars, green buildings, and energy service companies, and offering areas that are underserved, including residential low-income and moderate-income households and multifamily housing.

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.

This report lays the groundwork for a dialogue to explore regulatory and policy mechanisms for ensuring that efficiency financing initiatives provide value for society and protection for consumers. Through case studies of Connecticut, New York, Massachusetts, California, and Maryland, it explores emerging issues that jurisdictions will need to tackle when considering an increased reliance on financing.

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.

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.

The California investor-owned utilities -- Pacific Gas and Electric (PG&E), Southern California Edison (SCE), Southern California Gas (SoCalGas), and San Diego Gas & Electric (SDG&E), referred to collectively as the IOUs or Joint Utilities -- are designing seven energy efficiency financing pilot programs at the California Public Utilities Commission’s (CPUC's) direction. To help inform the pilot design process and subsequent evaluation efforts, this report summarizes a comprehensive review of 15 existing financing programs representing noteworthy program models across the United States and around the globe.

This report provides an overview of credit enhancements available, such as loan loss reserves, loan guarantees, debt service reserve funds, and subordinated capital. It also discusses key issues related to credit enhancement, examples of how others have successfully implemented credit enhancements as part of their energy efficiency financing programs, and additional information on existing resources that provide further information on credit enhancement design and implementation.

There are more than 17 million multifamily households nationwide, yet they remain a significant and mostly untapped opportunity for energy efficiency gains. Many cities and states that have embraced energy retrofitting as a job creator and boon to both the environment and economy have yet to address potential savings in multifamily properties, primarily because of obstacles not faced by single family and commercial properties. This paper discusses two barriers -- a lack of information and financing -- that stand in the way of multifamily energy retrofits.

This report provides an overview of the current state of on-bill programs and provides actionable insights on key program design considerations for on-bill lending programs.

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.
