Why Climate Zone 9 Matters Here

As part of Climate Zone 9 (Inland Valley (LA Basin)), Los Angeles projects are modeled against hot, dry summers and cool winters typical of the greater Los Angeles basin — which is why a report written for a different zone won't transfer directly.

Estimated from proximity to the nearest CEC reference station — we confirm the exact zone for your project's address before preparing your report.

Frequently Asked Questions

What is a Title 24 Energy Report?
+

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.

What format will my report be delivered in?
+

Your completed report is delivered as a signed PDF, formatted for direct upload to online permit portals or printing for in-person submittal — whichever your building department requires.

Do ADU projects in Los Angeles require HERS verification?
+

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 Los Angeles report we prepare.
