BC Step Code

BC Energy Step Code for Part 9 buildings — Step 3 provincial minimum

The BC Energy Step Code is a provincial regulation that local governments use to set energy efficiency standards in new homes built across the province. It consists of a series of steps, representing increasing levels of energy-efficiency performance. By adopting one or more steps of the standard, local governments can increase building performance requirements in their communities. The Province of British Columbia has set a goal that all new buildings must reach a net-zero energy-ready level of efficiency by 2032; the BC Energy Step Code serves as the policy pathway to achieve that goal.

Net-zero energy buildings produce as much clean energy as they consume. They are up to 80 percent more energy efficient than a typical new building and use on-site (or near-site) renewable energy systems to produce the remaining energy they need.

Net-zero energy-ready buildings have been designed and built to a level of performance that, with the addition of solar panels or other renewable energy technologies, could achieve net-zero energy performance.

Step Code offers Design Flexibility for Builders. Rather than examining a home’s individual components and prescribing minimum levels for each, the BC Step Code considers the house as a system and focuses more on overall energy efficiency. The house-as-a-system concept states that although separate, a home’s windows, doors, exterior walls, insulation, foundation, heating and cooling system, air-tightness and ventilation operate as a system. A change to one component will affect another. This allows for greater design flexibility and budget optimization. If a design calls for many windows, one can overcome the lack of thermal efficiency in that wall by increasing the wall thickness or insulation type. A home’s use of efficient mechanical systems for space and water heating can also overcome shortcomings in the building envelope. The BC Step Code promotes these principles to enhance energy performance standards across construction projects, encouraging sustainable building practices and innovation in the industry.b

Typical Process for Detached Homes, Duplexes, Townhomes & 3-Story Wood-Framed Apartments

The Designer/Builder works with an Energy Advisor to ensure the design meets the Targeted Step Code Level.
A Pre-Construction Compliance Checklist is completed by an Energy Advisor and submitted with the Building Permit Application.
A Mid-Construction Verification Checklist is done prior to the Insulation Inspection. This includes a Blower Door Test to assess Air Leakage through the Building Envelope and ensure the build is on track to meet the building efficiency requirements.
Once construction is complete, schedule a final Blower Door Test where the Energy Advisor will verify the building components. The Energy Advisor will complete an As-Built Compliance Report to be submitted with the Occupancy Permit Application.
Secure the EnerGuide Label in the home’s electrical panel (optional), and submit a copy with the Occupancy Permit Application.
