Energize Denver Hub - Existing Buildings

Denver is at the cutting edge of addressing climate change through regulations and programs aim to improve existing commercial and multifamily building energy performance while keeping equity as a priority. The Energize Denver Hub is your one-stop-shop to understand Denver’s existing building regulations, incentives and programs. By moving building owners to electrify their heating and cooling systems and improve energy performance, Denver will not only reduce greenhouse gas emissions from commercial and multifamily buildings by 80% by 2040, but also lower energy bills and improve public health outcomes.

Building electrification and performance standards are new to everyone in the building industry. We are working to roll out the resources you need to help you with this transition. More resources are always being added.

Buildings 25,000 sq. ft. or Larger

Buildings 25,000 sq. ft. or larger are required to submit annual benchmarking data and meet specific energy efficiency requirements. Learn about the requirements and how you can make sure you meet your energy efficiency goals.

Buildings 5,000-24,999 sq. ft.

Buildings between 5,000 and 24,999 sq. ft. are required to meet lighting or renewable energy requirements. Learn more about the requirements and find out how you can succeed in making updates to your building.

Buildings Under 5,000 sq. ft.

Existing buildings under 5,000 sq. ft. are not subject to any Performance Requirements. However, they are still subject to the requirements to partially electrify their buildings when replacing gas-fired heating and cooling equipment at the end of system life.

Resources for Contractors and Service Providers

Contractors and other service providers play an important role in helping our buildings to meet their Energize Denver requirements. Find resources and information for how you can support building owners and managers in understanding and acting on Energize Denver.
