Washington State Clean Buildings Performance Standard
The Clean Buildings Performance Standard consists of ASHRAE Standard 100-2018 and state amendments to ASHRAE Standard 100-2018, WAC194-50. Both documents must be used to understand the full scope of the Standard. This integrated document combines both and provides free of charge access to the full Clean Buildings Performance Standard.
Rulemaking to amend WAC 194-50 is from May-Dec 2023. Updated rules will be finalized by Dec 31, 2023. The Clean Buildings Performance Standard Integrated Document will be updated after the rules are codified.
