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.

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 details opportunities for scaling up program activity and increasing savings from programs reaching the people who need it most. It discussed best practices from existing programs for overcoming many of the key challenges that program administrators face, including how to address housing deficiencies that prevent energy efficiency upgrades, how to address cost effectiveness challenges, and how to serve hard-to-reach households.

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

Better Buildings Home Upgrade Program Accelerator partners, Build It Green, Enhabit, and NeighborWorks of Western Vermont, discussed steps for streamlining program processes, and strategies to improve data management, contractor relationships, and customer experiences. Tools and resources were presented as examples of how these ideas can be implemented in programs across the country.

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.

Home energy management systems (HEMS) continue to present a unique opportunity and challenge. While energy savings have been documented for many HEMS, some of the most promising opportunities from these devices and systems can be found in the internet of things (IoT) and smart home technologies. This report presents market updates, a regional goal, and strategies to drive market transformation and achieve the many benefits from HEMS and the Smart Energy Home.

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 summary from a Better Buildings Residential Network peer exchange call focused on how programs use behavior change strategies to reduce energy use.

This practitioner-focused Toolkit for Residential Energy Efficiency Upgrade Programs was created by Green For All to assist new, established, and future energy efficiency programs launch and scale initiatives that can deliver the full promise of the green economy. It is intended as a practical resource that offers examples, tools, and templates that a program manager can deploy to implement a variety of aspects of their program including best practice briefs and summary documents, RFPs, contracts, and other program design and implementation templates that communities nationwide have used to create their own efficiency programs.
