Addendum to Joint Appendix IV - Approved Alternative Construction Assemblies

If a construction assembly is not adequately represented in Title 24's Joint Appendix IV, an applicant may request approval by the Energy Commission's Executive Director for different data for that construction data. The Executive Director will base the decision on the application on the technical justification submitted by the applicant. Approved standard data for the construction assembly will be published as an addendum to Joint Appendix IV for use in all compliance approaches.

The following list is to be used as an addendum to Joint Appendix IV. Information sheets can be downloaded to be used as part of building compliance applications.

Subsequent alternatives will be attached in order of date approved.
