Building Performance Modelling

Passive House And EnerPHit Multi-Unit Simulation Tool Comparison

Multi-unit residential buildings (MURBs) house over a third of Canadians and represent the fastest growing source of housing in Canada, therefore reducing energy consumption in this sector has the potential to significantly contribute to meeting our greenhouse gas emission reduction targets. One path to reducing energy consumption in this sector is by adopting high-performance building standards such as Passive House for new construction and EnerPHit for retrofits. To achieve Passive House or EnerPHit certification, one must employ the Passive House Planning Package (PHPP) which evaluates annual building energy consumption using monthly temperature data. However, this modelling approach may not be endorsed by funding programs that require an hourly modeling approach.

The goal of this research is to conduct a comparative analysis of PHPP and an hourly modelling tool compliant with ASHRAE Standard 140 such as CanQuest. The modelling inputs, assumptions, modelling algorithms, as well as the key energy performance characteristics (i.e., TEUI, TEDI, and energy consumption of key end-uses) will be compared across the PHPP and CanQuest software packages by using the in-situ data from a new MURB complying to Passive House Standard. This study will compare and contrast the inputs and outputs of the two tools and highlight important deviations and identify the driving factors for these deviations.
