Abstract: This paper proposes a method of sensitivity analysis that is useful as a tool for energy code updates by assessing the potential increase of Key Performance Indicators (KPIs) due to changes in design input variables. Further updates of NECB-2017 prescriptive requirements should consider prioritizing modifications of design input values based on their impact on these KPIs. The sensitivity analysis of the energy efficiency of the case study building indicates that the minimum energy performance requirements of HVAC equipment, such as chillers, boilers, fans and pumps have the highest impact amongst the studied variables. Applying these changes to NECB requirements would significantly modify the KPI values at the wholebuilding, system and equipment levels.
