New Homes: BC Energy Step Code and Zero Carbon Code
BC Energy Step Code Requirements
Since May 1, 2023, B.C. has mandated an increase in the base energy efficiency requirement for new buildings by 20 per cent. This is equivalent to:
When you apply for a building permit from the RDN building inspection services after May 1, 2023, you’ll need to comply with this 20 per cent better requirement.
The recent updates to the building code have also introduced the Zero Carbon Step Code, which is an optional standard for measuring operational carbon emissions in buildings. To learn more about this, visit Building Inspection Services.
Current Initiatives Supporting BC Energy Step Code
Industry Training and Survey
The Regional District of Nanaimo and Community Energy Association (CEA) are seeking input from local builders, trades, and building professionals to help identify the support needed for businesses to achieve higher levels of the BC Energy Step Code. Your feedback will guide the development of upcoming training opportunities offered by the RDN in partnership with the CEA.
The survey will explore:
- What topics and resources are most valuable for advancing energy-efficient building practices
- Preferred training formats to maximize accessibility and effectiveness
- The best ways to communicate and engage with industry professionals
Complete the survey by November 2, 2025, and enter for a chance to win a $150 gift card to the store of your choice (conditions apply).
This survey will take approximately 8-10 minutes to complete.
What is the Zero Carbon Step Code?
The Zero Carbon Step Code sets a maximum annual amount of greenhouse gas emissions that each building is allowed to emit. The amount for each building is based on the proposed occupancy and the size of the building. The primary metric that is used is kilograms of carbon dioxide equivalent per square meter, per year (kg CO2e/m2/year). The details of the standards can be found on the provincial BC Energy Step Code website and the convenience copy of the BC Building Code update.
Similar to the BC Energy Step Code, the Zero Carbon Step Code has four levels each with a specific intent outlined below:
- Emissions Level 1: Measure-only (requires measurement of a building’s emissions without reductions and is intended to build knowledge and capacity)
- Emissions Level 2: Moderate Carbon Performance (in most cases, will require electrification of either space heating or domestic hot water systems)
- Emissions Level 3: Strong Carbon Performance (in most cases, will require electrification of both space heating and domestic hot water systems)
- Emissions Level 4: Zero Carbon Performance (in most cases will require the full electrification of a building)
