Why Climate Zone 16 Matters Here
Challenge's designation as Climate Zone 16 reflects cold winters and heavy snow loads, requiring the strictest insulation values in the state, 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.
