Thirty-five percent of all households now rent, and more than 60% of all rental housing, totaling 30 million households, is in the multifamily sector. However, efficiency measures are far less likely to be installed in multifamily rentals than in any other type of housing, leaving significant energy savings unrealized. Studies estimate that energy efficiency could cut the multifamily affordable housing sector’s electricity usage by as much as 26%. The share of low-cost rental units continues to decline either through gentrification, removals or rent increases. As a result, 24% of U.S. renter households—about 20 million—now spend more than 50% of their annual income on housing. Energy efficiency and renewable energy upgrades serve as an effective strategy to slow these trends and preserve affordability.
