The effect of occupant behaviour on energy consumption in conventional vs. high-performance residential buildings

Abstract: With aggressive energy reduction targets expected in MURBs driven by codes like NECB 2015 (NRCan, 2017) aimed at more efficient building codes and HVAC, the share of lighting and appliance loads will likely increase, causing occupant behaviour to have a greater impact on overall energy consumption. To better quantify this trend, this simulation study compares the effect of three occupant scenarios, in a high-performance and conventional MURB. Using operating schedules based on assumptions for these occupant scenerios, the high-performance building was found to use between 50% and 60% less energy than the conventional building. It was also found that for the high-performance building, hot water and appliance energy consumption represented more than 50% of total energy consumption, which was on average 20 percentage points higher when compared to the conventional building. This study highlights the energy end uses that are more susceptible to occupant behaviour as building envelope performance increases.
