Frequently Asked Questions
A Title 24 Energy Report is a California-mandated compliance document that demonstrates a building project meets the energy efficiency standards in Title 24, Part 6 of the California Code of Regulations. It's prepared using state-approved software and is required for most building permits involving conditioned space.
Apex provides Title 24 documentation services for projects in El Portal, including ADUs, garage conversions, room additions, residential remodels, new construction, HVAC or window alterations, and commercial work. The required compliance process depends on the project scope and permit requirements.
It depends on the compliance path used in your energy model. Certain prescriptive credits — duct sealing, refrigerant charge verification, air leakage testing — trigger a HERS verification requirement. We flag these clearly in every El Portal report we prepare.
