This literature review describes what is currently known about the occupant health benefits resulting from residential energy efficiency or work that is consistent with home performance upgrades. Of particular interest are the occupant health impacts associated with work typically conducted by the home performance industry, such as: air sealing and insulation; properly-sized, selected, matched, and installed energy efficient heating, ventilation, and air conditioning (HVAC) systems; identification and correction of moisture problems; proper whole house and room ventilation; lighting; and additional services including the replacement of appliances; measurement and installation of whole house and room air filtration systems (e.g., air purifiers); and basic pest exclusion. The intent of this literature review is to examine research that assessed work that would not be expected to harm residents or the workers.

This paper analyzes Bank of America's $55 million initiative to provide low-cost funding and grant support to advance energy efficiency investment in low- to moderate-income communities. The funding supported community development financial institutions (CDFIs) in developing and enhancing efficiency programs for residential, commercial, and multifamily buildings. We report on loan performance, energy savings, and the degree to which the savings offset the cost of the energy efficiency investment.

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.
