Why Climate Zone 9 Matters Here
Castaic's designation as Climate Zone 9 reflects hot, dry summers and cool winters typical of the greater Los Angeles basin, a factor our energy models account for when calculating your compliance margin.
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
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.
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.
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 Castaic report we prepare.
