A Case Study of an Occupancy-Based Energy Audit Model for Hotel Buildings

The hotel industry is among the highest consumers of energy of all building sectors. However, its energy consumption is largely dependant on hotel occupancy. The energy forecasting model has previously little considered occupancy in predictions. To supplement this research gap, interviews and data collections were conducted with a hostel in Singapore that is indicative of hotel owners' perspectives and concerns. Next, an occupancy-based energy auditing model was developed to allow better understanding of the calibration process for energy forecasting. The results show the importance of incorporating occupancy in the energy audit model and also show the estimation accuracy within 5-7% compared with the actual result.
