Abstract

Currently, typical air-conditioning schedules used in facility design often assume certain fixed durations of continuous operation; however, these are not applicable to rooms that are not regularly used, such as meeting rooms. Owing to this, there might be discrepancies in the selected capacity of an airconditioning unit and the calculated primary energy consumption of the building. In this study, we performed a Monte Carlo simulation, which stochastically decided the operation time of air conditioners based on the state transition probability of room occupancy. Further, using this model, we investigated the effect of irregular room usage on the heat load calculation.
