The multifamily housing sector offers unique opportunities for decarbonization over the next decade. Thirty-six percent of U.S. households now rent, and more than 60% of the rental market is in multifamily buildings, accounting for 27 million households. Uptake of energy efficiency measures in multifamily housing has lagged other types of housing, leaving significant unrealized energy savings on the table. Those savings can be captured with deep energy retrofits and renewable energy upgrades, which increases affordability for residents while in the long term helping preserve affordable housing by lowering operating expenses.
