Why Climate Zone 2 Matters Here

Glen Ellen's designation as Climate Zone 2 reflects a moderate maritime climate with mild summers and cool, wet winters, 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

Is a Title 24 report the same as a HERS rating?
+

No. The Title 24 report (CF1R) is the energy design document submitted with your permit. HERS verification is a separate field inspection process — required only for certain compliance credits — performed by a certified HERS rater during construction.

Can I submit my Glen Ellen Title 24 report online?
+

Most California building departments, including Glen Ellen Building Department, now accept digital permit submittals. We deliver every report as a properly formatted PDF ready for upload.

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.
