The original citizen-led Green Roof Ordinance became Denver’s Green Buildings Ordinance that provides flexible compliance options while honoring the original vote. Denver’s Green Buildings Ordinance requires all existing buildings to install a cool roof at roof replacement as well as choose one of the five compliance paths. The Energy Program under Energize Denver is one compliance path of the Green Buildings Ordinance for existing buildings.
