This paper describes the changes in indoor environmental quality (IEQ) conditions (air quality and thermal comfort conditions) from health and home performance improvements in 16 apartments serving low-income populations within three buildings in different California climates and seasons.

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 provides information and tools for policymakers, regulators, utilities, shared renewable energy developers, program administrators and others to support the adoption and implementation of shared renewables programs specifically designed to provide tangible benefits to low income and moderate income individuals and households.

Energy burden is the percentage of household income spent on home energy bills. In this report, ACEEE, along with the Energy Efficiency for All coalition, measures the energy burden of households in 48 of the largest American cities. The report finds that low-income, African-American, Latino, low-income multifamily, and renter households all spend a greater proportion of their income on utilities than the average family. The report also identifies energy efficiency as an underutilized strategy that can help reduce high energy burdens by as much as 30%. Given this potential, the report goes on to describe policies and programs to ramp up energy efficiency investments in low-income and underserved communities.

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.

The purpose of this study is to furnish comprehensive information on ratepayer-funded low-income energy programs. This study includes information on and analysis of the energy needs of low-income households, the legal and regulatory framework supporting ratepayer-funded programs, program design options, and the findings from evaluations of program effectiveness.

This report provides state and local policymakers with information on successful approaches to the design and implementation of residential efficiency programs for households ineligible for low-income programs.

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 multifamily showcase project profiles the significant energy improvements as well as annual energy savings of 20 percent and cost savings of $68,000 at Los Robles Apartments located in Union City, CA. Los Robles was one of the first Low Income Housing Preservation and Residential Homeownership Act (LIHPRHA) projects in the country to leverage Low-income Housing Tax Credits (LIHTC) and private capital to finance comprehensive energy- and water-efficiency retrofits.
