Energize Denver Electrification Program - Existing Buildings

The Energize Denver Ordinance required Denver to update its building code to phase in a set of requirements for existing commercial and multifamily buildings to replace gas-fired heating and cooling equipment with electric alternatives (like heat pumps) at the end of system life. The first requirement, which went into effect on March 1, 2023, just changes the permitting process for pulling a permit for heating and cooling equipment replacement. Further requirements will go into effect in 2025 and in 2027. These requirements affect ALL commercial and multifamily buildings, regardless of size.
