The objectives of this study are to evaluate air Received 5 May 2011 management and energy performance of cooling system and investigate the possibilities of energy saving Accepted 29 August 2011 and reuse in the data center. Field measurements, particularly for long term’s IT and facility powers, were conducted. Different performance metrics for the cooling system and power consumption were Keywords: examined and analysed. Key problem areas and energy saving opportunities were identified. The electrical Data center end use breakdown was estimated. Results show that IT equipment intake conditions were within the Air management recommended or allowable ranges from ASHRAE. The Power Usage Effectiveness (PUE) value for a typical Energy performance Return Temperature Index (RTI) year was about
