Energy Assessments

Energy Assessments


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.


Every ten years, affected building owners must perform energy assessments that meet or exceed the requirements below per the Standard for Commercial Building Energy Audits as published by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) in 2018 (Standard 211), and as updated periodically.

Building Size Energy Assessment Required Scope
Buildings < 50,000 SF     ASHRAE Level I assessment (Also offered by Xcel Energy, will comply)
Buildings ≥ 50,000 SF     ASHRAE Level II assessment (Not currently offered by a local utility, Xcel Energy audits do not comply)

Note: For manufacturing buildings, an electrical utility’s process efficiency assessments and studies can meet this requirement, if the scope is approved by the City Manager.

Report Templates

Report templates are available that include current ASHRAE requirements and City Manager Rule requirements to ensure compliance with the ordinance. The use of these templates is not required, however they can be a reference to ensure all requirements are included in the report.

Level II Energy Assessment Report Template docx 

*Note: If completing the Level I Energy Assessment through Xcel Energy's Onsite Energy Audit Program, that report will suffice for compliance.

Cost Saving Opportunities

Level I Energy Assessments

Xcel Energy offers an Onsite Energy Audit* for a small fee. These audits will be accepted for compliance with the Level I requirement of the ordinance  as long as the audit covers both electricity and natural gas equipment. 

Level II Energy Assessments

Buildings 50,000 SF and larger must provide the capital to complete a Level II assessment. Because these are not offered by a local utility, to help offset these costs, the city is offering rebates for buildings required to complete a Level II energy assessment.
