Why Climate Zone 16 Matters Here

Washington falls within California Climate Zone 16 (Mountain), an area defined by cold winters and heavy snow loads, requiring the strictest insulation values in the state. This classification directly shapes the insulation, glazing, and HVAC efficiency values used in your compliance calculation.

Estimated from proximity to the nearest CEC reference station โ€” we confirm the exact zone for your project's address before preparing your report.

Frequently Asked Questions

Do ADU projects in Washington require HERS verification?
+

It depends on the compliance path used in your energy model. Certain prescriptive credits โ€” duct sealing, refrigerant charge verification, air leakage testing โ€” trigger a HERS verification requirement. We flag these clearly in every Washington report we prepare.

What's the most common project type you handle in Washington?
+

ADU and garage conversion projects make up a large share of the Title 24 reports we prepare for Washington, followed by room additions and HVAC/window remodels.

Do you handle both prescriptive and performance compliance paths?
+

Yes. We evaluate every project against both paths and recommend whichever gets you to compliance with the least cost and complexity โ€” sometimes prescriptive is simpler, sometimes performance modeling unlocks more design flexibility.
