Abstract: The Canadian National Building Code requires heating system to be sized using CSA Standard F280-12 for low-rise residential (NBC Part 9) buildings. Although, heating system sizing is a Code requirement, most municipal jurisdictions outside of Ontario have either not adopted yet the requirement as province lag on code or municipalities failed to enforce it. There are a number of commercial software or custom in house software methods that claim to replicate F280-12 calculation; however, there is no third-party verification for these software packages. It is therefore difficult for industry and municipalities to confirm compliance to the requirements in the Standard. A testing procedure for F280-12 software packages is developed and verified using several archetype houses. The compliance procedure, when adopted, would enable housing industry to gain confidence in F280-12 heat loss and gain calculations. A novel method to test these software packages is proposed.
