Why Climate Zone 1 Matters Here

As part of Climate Zone 1 (Far North Coast), Carlotta projects are modeled against cool, foggy coastal conditions with mild year-round temperatures and a heating-dominant load — 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 climate zone is Carlotta in?
+

Carlotta is located in California Climate Zone 1 (Far North Coast). This zone determines the specific insulation, window, and HVAC efficiency requirements that apply to your project.

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.

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.
