In line with the City of Surrey’s climate action plan, our project investigated changes in energy usage, emissions and costs of retrofitting and electrifying a 1990 low-rise multi-unit residential building. By comparing ‘original’ and ‘retrofitted’ models, we found that electrifying building systems and improving the building envelope can reduce energy consumption and greenhouse gas emissions. However, the building envelope upgrade is acheived at a relatively high cost. Finally, our analysis on installing electric vehicle charging stations may help promote the technology in retrofitted buildings. Expanding the steps to meet newer building energy standards is essential to support retrofitting and electrification.
