The starting point
Energy requirements depend on the building, work, municipality and applicable permit date. The BC Energy Step Code and Zero Carbon Step Code address different performance questions. Do not assume a new-construction step automatically applies to every existing-home renovation; Vancouver's framework also needs its own check.
Check the applicable requirement before design#
The Province's requirements page ties Step Code requirements to project location and building-permit date. Establish which code and local requirements apply before selecting a target or quoting a step number.
Record whether this is a new building, addition or alteration, the building category and anticipated permit date. Take those facts to the local building department and the appropriate energy specialist. A BC-wide article cannot substitute for that determination.
Energy efficiency and carbon are separate checks#
Prepare separate questions about energy performance and operational carbon requirements. A choice of heating equipment does not by itself prove that the whole building meets its required performance level.
Ask an energy specialist which model, design-stage submissions, testing and completion documents apply. Coordinate envelope and mechanical decisions early so the drawings and performance documentation describe the same design.
Before you apply
- Confirm jurisdiction, building category, scope and permit date.
- Verify applicable Energy and Zero Carbon requirements separately.
- Engage the relevant energy specialist early.
- Coordinate design, modelling, testing and completion documents.
