Prescriptive or Performance? Which code compliance path is best for you?
Section 9.36 of the National Building Code and Alberta Building Code allows for two compliance paths:
The 9.36 Performance Path is likely to be the primary compliance tool for most professional builders. The Performance Path compares the modeled consumption of a builder’s Proposed house to the modeled consumption of an identical Code Reference house.
If the modeled consumption of the Proposed house is lower than the Code Reference house, then it is deemed to comply with section 9.36 of the NBC/ABC.
Upon completion of construction, an air-tightness test is conducted, and an EnerGuide Rating System label is issued from Natural Resources Canada.
The 9.36 Prescriptive Path establishes minimum specifications for all thermal elements of the building construction. In addition to mechanical/ventilation requirements, this includes minimum effective R-values for all wall, ceiling & foundation assemblies.
In most cases, the Prescriptive Path requires higher levels of construction assemblies than the Prescriptive Path. However, there can significant administrative savings for larger production builders if you use consistent construction specifications across all of your projects.
