Why Climate Zone 2 Matters Here
Because Napa is located in Climate Zone 2 — North Coast — projects here are evaluated against energy targets tuned for a moderate maritime climate with mild summers and cool, wet winters.
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
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 Napa report we prepare.
Most California building departments, including Napa Building Department, now accept digital permit submittals. We deliver every report as a properly formatted PDF ready for upload.
