Do you have a sample to share in the gallery?
The eQUEST building energy modelling software was used to model a five-story apartment building constructed between 1980 and 1990 in Metro Vancouver, and a Passive House certified retrofit of the same building. Comparisons of electricity and gas consumption showed that retrofitting the building led to an increase in electricity consumption and a decrease in gas consumption. Discovering these results is important because of the increase in population and the COVID-19 pandemic. With more people staying home, the energy consumption of the residential sector will increase and could impede the 2050 net-zero emission target in place within Metro Vancouver.
This project was initially published on the SFU School of Sustainable Energy Engineering Student Project Showcase: Comparison Between Conventional and Passive House Certified Apartment Buildings in Metro Vancouver.
