    EXPO2005 was held from Mar.25 to Sep.25 in 2005. In this EXPO Nagakute area, air-conditioning energy were supplied from five DHC plants. We had recorded air-conditioning energy, gas, power, and upper and lower water consumption in this area. In this study, we chiefly analyze the operation results of these DHC plants. As a results, main three plants had tended to operate in a lot of numbers of the refrigerating machine for the load. In that situation, plant No.6 which was subdivided to four showed better COP value, and importance of quipment composition of plants was confirmed. And, it was problem that excessive load calculation of enterprise pavilions influenced the plant load factor decrease.
