The BC Energy Step Code is a provincial building regulation that outlines energy efficiency requirements for new construction and major renovations of certain building types in British Columbia. The code provides a tiered approach to energy efficiency, with an increasing level of performance for each tier. Step 1 is the minimum requirement, while Step 5 is the highest level of performance and is equivalent to a net-zero energy ready building. The code is intended to reduce energy use and greenhouse gas emissions from buildings, as well as help move B.C. towards a low-carbon economy.
