Rules and Technical Guidance

With an update to the rules and regulations completed on April 1, 2025, we’ve 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 for building owners that are already in compliance with the LED lighting requirements and do not need to make lighting upgrades. 
  • Timeline extensions simplified: The process for timeline extensions is easier.   
  • Energy tracking: Where one year of energy tracking is required for renewable energy or the 15% Energy Use Reduction option, a simplified process is available. 
  • 15% Energy Use Reduction streamlined: building owners who are approved to do energy efficiency upgrades in place of LED lighting or renewables are no longer required to perform 12 months of energy benchmarking after the completion of upgrades. 

The latest version of the Technical Guidance will be available in Spanish by May 2025. If you require the Technical Guidance in a different language, please email us at energizesmallbuildings@denvergov.org.
