For example, under step 2, the code requires a building envelope energy demand of less than or equal to 45kWh/m2-year. Only performance targets defined, instead of prescriptive targets, like insulation values.
This is a big departure from the current energy code requirements (such as ASHRAE 90.1-2010) which is much more prescriptive.
Ok, but why should I care?
Effective Dec 15, 2017, cities no longer have legal force to set technical energy requirements. They must adopt some version of the BC Energy Step Code.
Note that the City of Vancouver is exempt from the code as Vancouver has its own Building By-Law. However, they have adopted very similar standards to the BC Energy Step Code.
So which cities have currently adopted the step code?
To date, only the City of North Vancouver has adopted the code for Part 3 buildings.
However, 17 cities in BC, including almost every city in the Lower Mainland has notified the province that they are intending to implement the code.
