Abstract: If it is performed on optimal design when designing a heat source system, it is unable to continue to maintain the performance without appropriate operation assessment. In this study, we propose performance management methods of the heat source system using a simulation model, and the development of a technology capable of maintaining many buildings remotely as the purpose of this study. In this paper, the simulation model of a whole heat source system and equipment unit with different input values as intended for industrial facilities is developed. Therefore, a fault detection method using a simulation model is studied. In addition, fault detection method by comparison of the measured value is studied. As a result, it was found that there is a possibility to find an equipment faults and sensor errors by comparing the measured data and the results of unit model calculation and system model calculation. Also, Fault detection method by comparing the measured values can be very useful by combining with fault detection method using simulation.
