This study is to obtain the characteristics of the seasonal system COP to evaluate heat source system efficiency. To reduce CO_2 gas emission caused by the energy consumption of commercial buildings, the heat source system is required to be upgraded. For this purpose, it is essential to evaluate and judge the performance of the heat source system correctly, while admitting the seasonal system COP to be the important efficiency ratio. However, the examples of study on the COP characteristics in heat source systems have scarcely been found and moreover, the actual statuses of the seasonal system COP in the existing buildings have not mostly been clarified. Preparing a model building and using the "Energy unit requirement control tool" program newly developed, this study theoretically analyzes the characteristics of the seasonal system COP to obtain the typical numerical values, features, and factors to be affected. The result of this study in understanding the characteristics of the seasonal system COP is expected to promote effective energy saving by applying it to building M & E service systems.
