Why Climate Zone 9 Matters Here
Altadena falls within California Climate Zone 9 (Inland Valley (LA Basin)), an area defined by hot, dry summers and cool winters typical of the greater Los Angeles basin. 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 — we confirm the exact zone for your project's address before preparing your report.
