Heat Loss Calculation Windsor
CSA F280 heat loss calculations for Windsor building permits, at the correct OBC design temperature for Essex County — BCIN-stamped, accepted by the City of Windsor Building Division, delivered in 48 hours.
A Windsor building permit requires a CSA F280 heat loss calculation at Windsor OBC January 2.5% design temperature of -16°C (Supplementary Standard SB-1). Windsor has the mildest design temperature in Ontario, so equipment sized for colder zones is oversized here. We deliver a BCIN-stamped report with the MVDS and Schedule 1, formatted for Cloudpermit. From $395, delivered in 48 hours.
Windsor design temperature: -16°C
Under OBC Section 9.33.2.2, your CSA F280 calculation must use Windsor official January 2.5% heating design temperature from Supplementary Standard SB-1: -16°C (about 3,400 heating degree-days below 18°C). Windsor has the mildest design temperature in Ontario, so equipment sized for colder zones is oversized here. Using the wrong design temperature is the single most common reason Ontario heat loss reports are returned, so we confirm the SB-1 value for your exact project location before calculating.
