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

The multifamily sector can be hard to reach when it comes to energy efficiency programs. Besides being diverse and complex, the sector presents a unique set of challenges to efficiency investments. The result is that multifamily customers are often underserved by energy efficiency programs. Drawing on data requests and interviews with program administrators, this report summarizes the challenges to program participation and identifies best practices that programs can use to reach and retain large numbers of multifamily participants.

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.

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.

This report presents the results of ACEEE's third national review or utility-funded energy efficiency programs, completed in 2013. The report identifies and profiles 63 leading programs that span the wide array of program types offered to utility customers, and highlights key trends and observations that emerged from reviewing these programs.
