2020 Model National Energy Codes for Buildings nearing final stages
The 2020 version of the National Building Code and National Energy Code for Buildings will have performance-based tiers moving towards higher levels of energy efficiency. Like the BC Energy Step Code, tiers enable provinces and municipalities to move towards higher levels of energy efficiency sooner, while ensuring cross-national harmonization and certainty for industry.
The highest tiers reflect net-zero energy-ready (NZER) performance. An NZER building is so energy efficient that it can supply its own energy needs with on-site renewable generation across the course of a year. The Pan-Canadian Framework on Clean Growth and Climate Change has set a goal that all provinces will adopt the NZER standard by 2030.
While these model codes are nearing their final stages of development, the full building code is not expected to be published until December 2021.
