The document discusses the Denver Housing Authority's efforts to promote green and affordable housing. It provides examples of the authority's redevelopment projects that focused on mixed-income housing and energy efficiency. These included installing geothermal systems, solar panels, and high-performance windows to reduce energy costs. The authority also used public engagement and health impact assessments to gather community goals for its projects and ensure the redevelopments provided social and environmental benefits.
