Boulder Building Performance Efficiency Requirements

Boulder Building Performance Efficiency Requirements


The City of Boulder is officially extending the 2021 compliance deadlines associated with the Boulder Building Performance Ordinance (Ordinance No. 8071) in order to minimize near-term impacts as area businesses continue to recover from the economic impacts of COVID-19. Specific deadlines that are to be extended are:

  • Energy Assessment requirement for all buildings 30,000 to 49,999 square feet extended from June 1, 2021 to Dec. 31, 2021;
  • The One-time Lighting Upgrade requirement for all buildings 50,000 and greater (including city facilities) extended from June 1, 2021 to June 1, 2022; and,
  • Retro-commissioning Report requirements for all buildings over 50,000 square feet and larger (including city facilities) extended from June 1, 2021 to June 1, 2022. All Retro-commissioning Measure Implementation requirements will be moved from June 1, 2023 to June 1, 2024.

There will be no change to June 1, 2021 Rating and Reporting deadline for all buildings 20,000 square feet and larger including city facilities.

Efficiency Requirements

The Building Performance Ordinance requires each affected commercial and industrial building owner to implement efficiency actions over a phased timeline. These actions are:

  1. Perform Energy Assessments Every 10 Years
  2. Implement One-time Lighting Upgrades
  3. Perform Retrocommissioning (RCx) Every 10 Years
  4. Implement Cost Effective RCx Measures


The efficiency requirements are phased in based on building size with  June 1  deadlines of the year listed below.
