To meet the challenge of the climate crisis, cities need to improve the energy efficiency of all buildings, including small buildings like single-family homes and owner-occupied buildings with just a few housing units. Cities must also take ambitious action to advance a clean energy future in a way that reaches all residents, particularly those living in communities that have been chronically underserved, underinvested, and under-resourced.

This guide discusses policy and program strategies that cities can pursue to achieve these goals. Drawing from the experience of local governments, the guide shares lessons and best practices that can support successful and equitable outcomes.
