Rules and Technical Guidance

Updates as of July 8, 2025:

Section 3.1.3, Self Verification. An individual unit owner cannot complete self verification for a single unit in a multi-tenant building. The building must complete self verification for all units in the building and submit them together.

Section 3.2.1, Renewable energy compliance. You must include a copy of one (1) of the energy bills that you used to calculate energy site usage must with compliance documentation.  

Section 4.3, Timeline Extension. Buildings that are currently for sale may receive at most a one (1) year timeline extension. You must submit a copy of an agreement with a real estate agent. This will serve as evidence that the building is currently for sale. If the building remains for sale after the one (1) year timeline extension has expired, the building owner may re-apply for an additional (1) year timeline extension. You will have to provide the same supporting documentation for the second application.

Updates as of April 1, 2025:

We updated to the rules and regulations completed on April 1, 2025. The update increased the options available to help put compliance for small buildings within reach. The city made the following updates to Energize Denver to support buildings 5,000 – 24,999 sq. ft. with a more practical, achievable compliance process: 

• Already in compliance with LEDs? Self-verification is now allowed. This only applies to buildings that do not need to make any additional upgrades to get into compliance.
• Timeline extensions simplified. The process for timeline extensions is easier.   
• Energy tracking. We simplified the process to provide one year of energy tracking for the renewable energy and the 15% Energy Use Reduction option.
• 15% Energy Use Reduction streamlined. Benchmarking after compliance is no longer required for the energy efficiency compliance option.
