Why Climate Zone 12 Matters Here
As part of Climate Zone 12 (Central Valley), Thornton projects are modeled against very hot summers and cool, often foggy winters — 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
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.
At minimum we need the site address, a dimensioned floor plan, window schedule, proposed HVAC and water heating equipment, and insulation values. The more complete your plans, the faster we can turn around your report.
Most California building departments, including Thornton Building Department, now accept digital permit submittals. We deliver every report as a properly formatted PDF ready for upload.
