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.

This report identifies opportunities for Connecticut's Home Energy Solutions program (HES) to increase savings related to air sealing, duct sealing, and insulation.

This report is the process evaluation of the Connecticut Multifamily (MF) Initiative, which leveraged the state's Home Energy Solutions (HES) and Home Energy Solutions-Income Eligible (HES-IE) programs. The objective of this process evaluation is to provide actionable recommendations about how to improve the design, delivery, and administration of the MF Initiative.

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 report includes evaluation analysis and findings from the Eversource New Hampshire Home Energy Report pilot program.

This report presents the results of the evaluation of National Grid Rhode Island's 2014 EnergyWise program. EnergyWise is designed to achieve energy savings in single family (1-4 unit) residential homes by directly installing efficient lightbulbs and water heating measures, providing devices for homeowner use, and offering building shell retrofit rebates.

This report provides the electric and natural gas impacts from the suite of National Grid Multifamily Retrofit Programs as determined through a billing analysis.

This report summarizes the impact analyses of National Grid's and Eversource Energy's Home Energy Report (HER) programs. The evaluation team conducted three distinct impact analyses related to these HER programs: Cohort-Specific Impact Analysis; Mapping Analysis; and Dual Treatment Analysis.

This technical reference manual provides detailed, comprehensive documentation of resource and non-resource savings corresponding to the Energy Efficiency Fund program and individual Conservation and Load Management (C&LM) program technologies.

The study involved on-site visits to 180 single-family homes across Connecticut. The team assessed compliance with the weatherization standard using both the prescriptive and performance paths and made recommendations to improve program quality.

Three-part webinar series. Part I discusses how to design and implement funding programs, line up partners, and gain support for clean energy programs through both conventional and non-conventional methods. Part II discusses how to locate available sources of funding. Part III explains how to leverage existing funds and make clean energy investments more affordable for clean energy program audiences.

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 report presents results, recommendations, and case studies of energy efficiency financing programs.

This guide describes a structure and several model approaches for calculating energy, demand, and emissions savings resulting from energy efficiency programs that are implemented by cities, states, utilities, companies, and similar entities.
