This case study highlights how EmPOWER Maryland’s low-income programs have helped to reduce or eliminate the up-front costs of efficiency upgrades, minimize administrative burden on participants, and provide coordinated services through a statewide network of trusted partners. Under the Multifamily Energy Efficiency and Housing Affordability EmPOWER Program, owners of affordable multifamily housing receive loans and grants with flexible terms for the purchase and installation of a variety of energy improvements, from lighting and appliances to insulation and HVAC systems.

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 report reviews the costs and benefits of EmPOWER Maryland through 2015 with a focus on statewide benefits.

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 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.

This summary from a Better Buildings Residential Network peer exchange call focused on approaches to generate demand for energy efficiency upgrades at multifamily buildings.

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.

This summary from a Better Buildings Residential Network peer exchange call focused on combining solar and home performance energy efficiency.

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 report analyzes and develops estimates of non-energy impacts that could be included in cost effectiveness analyses for the EmPOWER Maryland energy efficiency programs. Four non-energy benefits are included in this analysis: air emissions, comfort, commercial operations and maintenance (O&M), and utility bill arrearages. In all four cases, a recommended value and methods for including them in future EMPOWER costs effectiveness analyses are provided.

Reviews and summarize energy efficiency financing models and strategies. Models are analyzed according to funding sources, program structures, limits to scale, repayment vehicles, and project risks. Strategies consider applicable building sectors, models, levels of establishment, growth potential, advantages, and disadvantages.

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 describes different approaches to energy efficiency finance taken by utilities.

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