Why Climate Zone 10 Matters Here
As part of Climate Zone 10 (High Desert / Inland Valley), Ontario projects are modeled against larger temperature swings with hot summers and cold winter nights — 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.
