CSA F280-12 is the Canadian standard for calculating residential heat loss and heat gain. In British Columbia, this standard is used to ensure heating and cooling systems are sized accurately for local climate conditions, energy efficiency requirements, and building code compliance.
We typically require floor plans, insulation details, window and door specifications, and your preferred HVAC system information.
For projects in BC, this information helps ensure calculations align with provincial code requirements and rebate program documentation.
Most heat load calculation reports are delivered within 1 to 2 business days after we receive complete drawings and project details.
This timeline supports fast-moving construction and retrofit schedules common across British Columbia.
Both. We complete heat load calculations for new home construction and for existing homes across BC undergoing HVAC upgrades, heat pump installations, or energy retrofits.
Many BC provincial and utility rebate programs, including those for heat pump upgrades, require a certified heat load calculation before incentives are approved. Accurate calculations also ensure your heat pump is properly sized for your home's design and local climate conditions.
Homeowners are responsible for submitting rebate applications, but we provide rebate-ready documentation to support the process.
An improperly sized system can lead to uneven temperatures, higher energy costs, reduced efficiency, and shorter equipment lifespan.
This is especially important in British Columbia's varied climate zones, where accurate load calculations help ensure reliable performance year-round.
