F280-12 Heat Gain and Loss 
 

F280-12 Heat Loss & Heat Gain Calculations provide a precise, engineering-based assessment of a home’s true heating and cooling requirements. Using CSA F280-12 methodology, we evaluate building envelope performance, insulation levels, air leakage, glazing, orientation, and ventilation loads to accurately determine design heating and cooling capacities. This ensures properly sized HVAC equipment—improving comfort, energy efficiency, system longevity, and code compliance—while preventing the common problems of oversized or undersized systems such as short-cycling, poor humidity control, and uneven temperatures.
