In Progress
2022 Cycle
The Statewide CASE Team has selected measures for inclusion in Nonresidential, Multifamily, and Single Family CASE Reports in the 2022 code cycle. These 2022 standards will continue to improve upon the 2019 standards for new construction of, and additions and alterations to, residential and nonresidential buildings.
We encourage stakeholders to email us feedback throughout the process. You can also participate in the 2022 Title 24, Part 6 Standards update by attending the Energy Commission workshops and submitting written comments to the rulemaking docket. To submit a comment to the Energy Commission, refer to the Pre-Rulemaking and Rulemaking Workshop Notices, or click here.
