Green Affordable Housing: HUD Has Made Progress in Promoting Green Building, but Expanding Efforts Could Help Reduce Energy Costs and Benefit Tenants

摘要

Rising energy prices and concerns about the environment have fueled interest in 'green building'--resource-efficient construction and maintenance practices that reduce adverse impacts on the natural environment. The Department of Housing and Urban Development (HUD), spends an estimated $5 billion on energy costs annually in its affordable housing programs and has recently taken steps to reduce its energy costs. GAO was asked to review (1) HUD's efforts to promote energy efficiency in its programs and the use of performance measures, (2) potential costs and long-term benefits of green building in HUD's affordable housing programs, and (3) lessons learned elsewhere that HUD could use to promote green building. GAO reviewed HUD program documents and studies on green building, interviewed HUD officials and industry representatives, and made site visits to locations that use green building practices. HUD has taken steps to promote energy efficiency by providing information, training, and technical assistance, but its efforts have limitations. HUD has also provided some financial incentives to promote green building, including energy efficiency, for public housing and for a small segment of the multifamily properties HUD supports.
