Canada is on the path to advancing its energy codes in residential construction. The 2020 National Building Code (NBC) will support higher degrees of energy performance in homes through a tiered energy code with the most stringent tier intending to approximate to ‘Net Zero Energy Ready.’ With a dataset of over 500 Net Zero and Net Zero Ready labelled homes across the country, the CHBA has performed a detailed analysis comparing these homes to the proposed Tier 5 metrics of the NBC.
