BC Zero Carbon Step Code for Builders
A practical guide to BC Zero Carbon Step Code levels, equipment decisions, and permit reporting. Confirm the local level before finalizing mechanical systems.
Confirm the project’s emission level before heating and hot-water equipment is ordered. A fuel or equipment change can alter the Zero Carbon result and force the permit model to be revised.
Most new BC buildings must meet at least EL-1, the measure-and-report level. A municipality can require more. The Energy Step Code measures energy performance; the Zero Carbon Step Code measures operational emissions.
Send heating, cooling, hot-water, ventilation, supplementary-heat, backup-heat, and control choices while they can still change. Use the municipality guide as a starting point; I confirm the active level against the building department’s current requirements and keep the Step Code report, HOT2000 model, and quoted F280 work aligned.
Code and local requirements can change. Confirm the active emission level for the permit date and municipality.
Know what each level asks the project to do.
- EL-1 records and reports emissions
- EL-2 and EL-3 require progressively lower operational emissions
- EL-4 is the zero-carbon performance level
- Local bylaws can require a higher level than the provincial minimum
Send the mechanical choices before they are fixed.
- Heating and cooling equipment type
- Domestic hot-water system and energy source
- Ventilation equipment and efficiency
- Supplementary and backup heat, including the control strategy
- Any building-department comments or project changes
What builders ask before booking.
What is EL-1?
EL-1 is the measure-and-report level of the Zero Carbon Step Code. It records operational emissions without setting the higher-level reduction targets.
Can a municipality require more than EL-1?
Yes. Local governments can require a higher emission level. Confirm the active level with the building department.
What should I send before modelling?
Send the heating, cooling, hot-water, ventilation, backup-heat, and control choices available for the project.
Does the Zero Carbon Step Code replace the Energy Step Code?
No. The two frameworks address different metrics and are reported together in the Part 9 compliance work.

Send the drawing set or a share link. Include the address, municipality, current stage, and target dates. I’ll confirm any missing inputs and quote the project by stage.
