Why Climate Zone 15 Matters Here
As part of Climate Zone 15 (Low / Imperial Desert), Thermal projects are modeled against extreme heat for most of the year with very high cooling loads — 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.

Yes. We evaluate every project against both paths and recommend whichever gets you to compliance with the least cost and complexity — sometimes prescriptive is simpler, sometimes performance modeling unlocks more design flexibility.
