New Homes - Energy Step Code

BC Energy Step Code Requirements
From May 1, 2023, BC has mandated an increase in the base energy efficiency requirement for new buildings by 20 per cent. This is equivalent to:

  • Step 3 for Part 9 (Simple) buildings, and
  • Step 2 for Part 3 (Complex) buildings.

When you apply for a building permit from the RDKB building inspection services after May 1, 2023, you need to comply with this 20% better requirement.

What is the Step Code?
Step Code is a performance-based compliance path in the BC Building Code. It sets out energy and airtightness performance targets for new buildings. Designers or builders decide how to meet these required targets.

Builders work with a certified energy advisor or a registered professional. They use energy modelling software and on-site testing to demonstrate that both the building design and the construction meet Step Code requirements.

The Step Code provides an incremental approach to make new buildings more energy efficient now and net zero energy ready by 2032. A net zero energy ready building is designed and built to achieve net zero energy performance by adding renewable energy technologies.
