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.

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.

Report that identifies and evaluates the sufficiency of available financing options to help low-income populations, particularly communities that have been historically overburdened by air pollution (i.e., "environmental justice communities"), invest in resource-saving measures, such as energy efficiency and water conservation.

This case study highlights the low-income programs of Efficiency Vermont, the nation’s first public energy efficiency utility, which aims to reduce these customers' high energy burden, freeing up money that they can spend on food, housing, and other necessities. These low-income programs have saved enough electricity to power nearly 8,000 Vermont households for a year and offer solutions that eliminate or reduce up-front costs for residents, a typical barrier to improving energy efficiency in low-income households. Its multifamily energy efficiency program helps renters and building owners save energy, addressing the “split incentive” barrier in which owners have little reason to invest in efficiency measures that benefit tenants who pay their own energy bills.
