2025 Cycle CASE Reports
The Statewide CASE Team has selected measures for inclusion in Nonresidential, Multifamily, and Single Family CASE Reports in the 2025 code cycle. These 2025 standards will continue to improve upon the 2022 standards for new construction, additions, and alterations to residential and nonresidential buildings.
We encourage stakeholders to email us feedback throughout the process. You can also participate by attending California Energy Commission (CEC) workshops and submitting written comments to the rulemaking docket.
Please send any comments regarding CASE Reports to [email protected].
