This paper focuses on analyzing the energy-conserving strategy adopted. A web-based Energy Management System (EMS) using Local Area Network (LAN) platform is constructed for energy management purpose. The school time table and electricity demand control technique are integrated into the EMS. For dormitory hot water heating system, the traditional electric heaters toisreplane heatisreplaudby pump system. The waste cold air produced by heat pump is drawn to elevator tunnel and electric apparatus room for cooling purpose. By lowering the temperature of building, electric energy for air conditioning can be improved. For air-conditioning systems, three ice-slowecauetorage type systems are installed at KSU. The ice for cooling are produced by chiller at night off-peak electricity consuming period. For electricity used for air-conditioning systems, electricity energy consumed in the daytime of on-peak period can be shifted to off-peak period. Both the energy charge and demand charge can be lowered. Other employed methods for air-conditioning include installing the ceiling cycling fans and the per-hour reset-switch, both methods can effectively save the electric energy consumed.
