Evaluation of energy performance of UBC's residential buildings using actual data Shin, Ji-Yeon


The Canadian residential sector consumes 20 per cent of Canada’s total secondary energy as shown in Figure 1 and there are many residential buildings that are currently being built on UBC campus. All the residential buildings on campus have to be constructed according to UBC’s own building rating system, the Residential Environmental Assessment Program (REAP), to ensure lower consumption of water, energy and other resources and higher-quality indoor environment than buildings that are built without any rating systems. However, REAP is applied during planning and construction phases and hence, it does not always guarantee lower energy consumption in the post-occupancy phase. This project was undertaken to assess the energy performance of UBC’s residential buildings using actual energy consumption data. The primary objective of this study is to analyze electricity and gas consumption of three of UBC’s Faculty and Staff Housing buildings. The main sources for this project are electricity and gas consumption data provided by UBC Utilities, building floor plans from UBC Infrastructure Development, and weather data. The average total energy intensity for the three buildings was found to be 165.4 kWh/m²/yr. For a more detailed break-down of energy analysis, individual suite metering for domestic hot water heating and gas fireplaces would be required.
