Abstract

This paper presents yearly energy use data of MUN Core Science Facility (CSF) building. The data shows that 12,876,967 kWhr of electricity and 38,432,359 kBTU of heat energy was used by the CSF building in 2022. Thermal model of CSF building is developed in Building Energy Optimization Tool (BEopt) using the collected building envelope parameters. Envelope parameters include R values of walls, windows, roofs, floors, and HVAC parameters such as total heating/cooling capacity, fan power, and outside air minimum ventilation. A comparison between actual energy consumption and consumption predicted by BEOpt is also included. The Simulink thermal model of CSF building is also developed to demonstrate that the building indoor temperature can follow varying set point temperature. Results show that the heat energy calculated by our BEopt model is 35,824,572 kBTU, which is only 6.8% less than the real CSF building heat energy use.
