Why Climate Zone 1 Matters Here
As part of Climate Zone 1 (Far North Coast), Petrolia projects are modeled against cool, foggy coastal conditions with mild year-round temperatures and a heating-dominant load — 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.
