The California Energy Commission is working to develop revisions to the 2019 California Building Energy Efficiency Standards (Tile 24, part 6). Below are the presentations from the Pre-Rulemaking Workshops held by the California Energy Commission regarding this code change cycle. There are also copies of the draft code language (please note that some draft code language is included in the presentation, while some are listed separately).

We are eager to receive your feedback and comments to the proposed code changes. If you have any comments or questions please contact Chris Walker at 916-363-7460 or chris@cal-smacna.org.
