Heat Loss Calculation Hamilton
CSA F280 heat loss calculations for Hamilton building permits, at the correct OBC design temperature for the Golden Horseshoe — BCIN-stamped, accepted by the City of Hamilton Building Division, delivered in 48 hours.
A Hamilton building permit requires a CSA F280 heat loss calculation at Hamilton OBC January 2.5% design temperature of -17°C (Supplementary Standard SB-1). Hamilton uses -17°C both above and below the Escarpment. We deliver a BCIN-stamped report with the MVDS and Schedule 1, formatted for the City of Hamilton ePLANS portal. From $395, delivered in 48 hours.
Hamilton design temperature: -17°C
Under OBC Section 9.33.2.2, your CSA F280 calculation must use Hamilton official January 2.5% heating design temperature from Supplementary Standard SB-1: -17°C (about 3,460 heating degree-days below 18°C). Hamilton uses -17°C both above and below the Escarpment. 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.
