Taking an opportunity to construct a new campus, we aimed for the new role model of the sustainable and next-generation campus that maintains high environmental performance over the future. The well-located campus enabled to construct environmental friendly buildings using natural energy in combination with the electricity and gas. Additionally, cutting- edge technologies including the All-air Introduction Radiant Air-conditioning System were introduced to the new campus. The combination use of energies and the advanced technologies provided a comfortable learning environment throughout the year and achieved energy saving as well as reduction of CO2 emission. We have continued promoting activities to save energy and to reduce CO2 emissions for two years since new campus was opened. Moreover, we have been working on the optimum campus operation by using commissioning and tuning techniques.
