Why Climate Zone 4 Matters Here
As part of Climate Zone 4 (Mixed Marine), Lathrop projects are modeled against coastal fog and moderate summers with cooling-dominant afternoons — 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.

At minimum we need the site address, a dimensioned floor plan, window schedule, proposed HVAC and water heating equipment, and insulation values. The more complete your plans, the faster we can turn around your report.
