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 explores how governments and energy efficiency implementers could help stakeholders better analyze and act upon building performance data to unlock savings.
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 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 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.
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.
Connecticut's Neighbor to Neighbor Energy Challenge uses dashboards that display key project data for administrators and contractors to monitor progress over time. The program has evaluated performance at different steps in the process and identified strategies to improve performance where needed, such as sales training for contractors, energy advisors, monthly contractor scorecards, and multiple customer "touches." These improvements increased the close rate from 26 to 60 percent in one year.
This presentation shares how the Neighbor to Neighbor Energy Challenge collected and evaluated data and used the results to improve its program.
