Energy consumption for air-conditioning such as generating hot and chilled water, air-handling, ventilating, etc. generally occupies about half of the whole in a building. Especially, the building energy consumption in university campus largely changes through a year and a day because the building includes different rooms such as class room, laboratory, experimental facility, office room, etc. and the way of the utilization is irregular. Furthermore, the air-conditioning operations in most of cases are inefficient due to the lower partial load rate because the air-conditioning system and the machine capacities are designed based on the maximum thermal load. This paper describes on the heating and cooling plant system which has been installed in a real university, and verifies the energy saving effects by the commissioning on the partial load operation problems using measured data stored in the Building Energy Management System.
