Abstract: The 2020 global pandemic had a great impact on lives of people. Where occupant behaviour is concerned, the increasing uncertainty of occupancy that COVID-19 had brought with it is one of them. This study investigated the effects of COVID-19 on energy consumption for office buildings through a case study approach where real-time data was used to generate realistic occupant schedule from four different periods before and during the pandemic. An energy simulation was carried out with the schedules using a representative model of office buildings in Singapore which generated scenario outputs from the permutation of four time periods and three different occupant behaviour styles (austere, normal and wasteful). The findings confirmed the uncertain nature of occupancy throughout the pandemic in comparison to Pre-Covid schedules where occupancy fraction was found to be (1) half of the occupancy during normal operation periods (2) dissimilar to established occupancy profile in office. It was also concluded through simulation that the change in occupancy behaviour (occupant fraction and behaviour style) have great effect on occupant-dependent building system (light and equipment) compared to the cooling system modelled. Cooling energy consumption efficiency was also seen to be most affected in the bottom perimeter zones and least affected in the core. Through further analysis, the study recommends the importance of including occupancy-centric metrics in building performance analysis when comparing between the widely-used building performance metric – Energy Use Intensity (EUI) and an Occupant-Centric Metric. It was also brought to light the need of improving the system to be more resilient to occupant changes as uncertainty in occupant behaviour increases.
