Energy Step Code

In April 2017, the Province of British Columbia adopted the BC Energy Step Code as regulation. The new standard is a tool designed to help both government and industry chart a course to a future in which all new construction across the province is “net-zero energy ready” by 2032.  For Part 9 homes, there a series of five (5) steps that incrementally increase the performance-based energy-efficiency requirements for new construction projects.

Step 1 entails modelling energy performance and measuring airtightness to ensure that a building will meet or exceed the minimum energy-efficiency requirements in the base BC Building Code. Meanwhile, at the opposite end of the scale, the highest step represents a “net-zero energy ready” standard – a standard that is being met by the most energy-efficient projects being developed today.

In short, the BC Energy Step Code provides more consistency to industry, establishing a standard set of performance requirements, while offering local governments a simple and effective set of standards to support their energy conservation and greenhouse gas reduction goals.  For more information on the Energy Step Code, visit energystepcode.ca
