In data centers, as there are many servers with high load density, power consumption at data centers becomes large for operation of server itself and air conditioning. In this research, energy performance of economizer system and free cooling are examined. In addition, hot aisle containment which separate the high temperature exhaust air from server and the supply air from air handling unit was proposed in order to maximize efficiency of air conditioning by preventing recirculation of the high temperature exhaust air. Then it was shown that economizer, free cooling and hot aisle containment are effective to reduce energy consumption of server room by simulation.
