Heat Loss: It is a calculation that determines the maximum amount of heat (Btu/h or KW) that is required to condition a building based on the outdoor winter design temperature. The outdoor winter design temperatures are established in section 9.33.3.2 of the 2012 Ontario Building Code. Heat Gain: It is a calculation that determines the optimum amount of cooling (Btu/h or Tons) that is required to best manage temperature (sensible) and humidity (latent) of a building, including considerations for solar gains through windows and internal heat gains from people and appliances.
