Abstract
The growing energy consumption of commercial buildings in the field of civilian sector strongly requires to take effective energy saving measures. Especially as the energy consumption of heat source system in office buildings occupies as high as about 30% of the total building energy consumption, the efficiency of the heat source system should urgently be upgraded. For this purpose, it is essential to grasp the annual thermal load fluctuation and corresponding operation status of the heat source system for analysis. At present, however, the examples of measurement survey of the energy efficiency ratio of the system in commercial buildings can scarcely be found. Backed by such circumstance as above, this study conducted actual measurement on the heat generation and energy consumption of the heat source system in three typical commercial buildings to grasp the operation status and energy efficiency ratio by employing the system COP as a performance index.
