BC Energy Step Code: connect the energy design with site work and verification
A residential project has an approved energy design, but a purchase substitution and several service changes have not reached the energy advisor. The insulation foreman needs a short list of inputs and responsibilities before the wall is closed.
For a site crew, the energy design needs to become located installation information and a clear answer route. Start with this project’s permit, applicable code, approved design and responsible advisor or modeller. The BC handbook describes checking actual enclosure, equipment and airtightness information against the as-built energy model. A neat insulation installation is useful evidence, but it cannot alone establish whole-building energy compliance.
Connect the design, work and verification
- Confirm this project’s compliance basis. Obtain the current energy documents and identify the building scope, applicable requirements and responsible contacts. Keep Energy Step Code performance questions distinct from Zero Carbon Step Code questions. Do not assume every BC project has the same required step, target, permit conditions or building-code pathway. Ask the project team to resolve a missing or conflicting basis.
- Translate the enclosure inputs into crew instructions. Identify the specified insulation products, thicknesses and positions, air-control route and relevant details. Put the instructions at the actual locations rather than quoting a performance target to a crew with no connection detail. Coordinate interfaces with service, window and framing trades. Mark what must remain accessible for the project’s assigned checks.
- Report a proposed change before it becomes hidden work. Give the responsible design and modelling team the actual substitution or altered detail. Include product information and location. Ask whether the change affects the accepted design or model inputs and what answer is required. A purchase approval does not necessarily settle energy performance, and an apparently higher product rating does not establish whole-wall equivalence.
- Coordinate the agreed verification and as-built record. Confirm the test boundary, preparation, responsible tester and reporting route from the actual process. Record completed checks, outstanding corrections and changes that affect as-built information. Use the authority’s required submissions. The handbook’s checklist process supports communication; do not assume one particular template is itself a statutory requirement on every project.
Common mistakes
- Assuming every permit requires the same energy step.
- Using a whole-building target as a missing installation detail.
- Leaving changed enclosure inputs out of the as-built review.
- Treating a photo or passed material check as whole-building compliance.
Checklist
The crew’s energy-design handover
- Current compliance basis and responsible contacts.
- Located insulation and air-control details.
- Interface owners and accessible checks.
- Reported substitutions and received answers.
- Actual test information and required as-built submissions.
Check your understanding
A substitute board has an attractive product R-value. Can the crew install it without asking about the approved energy design?
