In recently, universities are required to improve the quality of research environment and facilities. At this time, Kyushu University has been planned the moving of its major two campuses to a western part of Fukuoka city. The purpose of this study is to propose an optimal energy conservation system and to make a comfortable educational environment. The results are as follows : 1) The ratio of energy consumption being used in current campuses is electric power 90% and gas 10%. In the future, there are urged energy consumption balance and leveling the electric load profile. 2) The investigation in winter, we defined that education buildings are in need of ventilation with old equipment. There are deliberately required ventilating for indoor air quality. 3) On the comparison of the value of PAL through the changing the materials of building, we obtained that the numerical date of PAL are 244MJ/(m^2・year) on lecture buildings and 219MJ/(m^2・year) on research buildings. 4) The several techniques of HVAC system are effectively displayed within energy source (electric power), energy transportation (pump and fans). The result of CEC/AC is satisfied with next generation standard by the control of inverter with VAV and VWV.
