2022 CA Energy Code Updates – How they impact commercial and residential roofing
Presenter: Phil Dregger, PE, RRC, Fellow-IIBEC of Salas O’Brien
The 2022 CA Energy Code becomes effective 1.1.2023. It includes many new and changed requirements that impact how roof coverings are designed and installed in California. Example changes include expanded climate zones where air barriers are required, higher levels of thermal resistance (lower U Factors), a new requirement for installing minimum R10 insulation above roof decks, higher levels of solar reflectance for steep roofing, and a new section entitled “multifamily buildings”.
The presentation will explain how to apply the new requirements by working step by step through several real example roofing and reroofing projects, including low-slope and steep-sloped roofs and residential and commercial occupancies; which, by the way, each have different requirements.
Attendees are encouraged to bring copies of the 2022 CA Energy Code (Title 24, Part 6) with them (hard copy or digital) to get familiar with how to find and interpret the new requirements. Free digital versions of the 2022 CAT24P6 code can be accessed here – https://codes.iccsafe.org/content/CAEC2022P1
I propose to include new construction but spend more time on reroofing. I will only briefly mention new solar PV requirements. I will not address “performance” compliance options that rely on approved computer programs/software to show the energy efficiency of roofs.
