| Abstract | This paper presents the methodology developed to quantify operational GHG emissions and set performance levels in the proposed updates to be included in the 2025 edition of the National Building Code (pending approval). The GHG requirements build on the reference vs proposed method widely used in energy codes. Reference GHG emission factors were selected and verified using 240 contemporary house archetypes, which utilized natural gas for space and service water heating. From this baseline six performance levels (from A to F) were defined, with A being the most stringent (≥ 90% improvement compared with the target), and F the least stringent (<10% improvement). The results emphasized that the most significant reduction in GHG emissions can be attributed to changes in the electricity grid mix and equipment selection. In locations where average grid emissions factors are less than 100 g CO₂e/kWh, heat pump systems demonstrated the most significant reduction in GHG emissions compared to the reference, and ultimately compliance with higher operational GHG emissions performance levels (A and B). |
