Denver Green Buildings Ordinance

The City of Denver, Colorado established a Green Buildings Ordinance in 2018 requiring all new and existing buildings over 25,000 square feet in size to incorporate a “cool roof” along with other green energy measures. The new ordinance strengthens Denver’s 2017 green roof ordinance to go beyond vegetated roof requirements with additional, cost-effective options for reducing greenhouse gas emissions and addressing urban heat island effects across the city.

Specifically, the green buildings ordinance applies to:

  • New buildings 25,000 square feet or larger
  • Roof permits for existing buildings 25,000 square feet or larger
  • Additions of 25,000 square feet or larger

In addition to the requirements to include a cool roof, one of the following green energy or green infrastructure components are required:

  • Green space or green roof
  • Payment to a Green Building Fund
  • On-site solar panels
  • Purchase of off-site solar energy
  • Energy conservation measures
  • Green Building Certification
  • or combined approaches

Compliance to the Green Buildings Ordinance is required for all applicable building and roof permits. The linked Denver Development Services website provides compliance guidelines for cool roofs and all other suitable approaches.
