With the increasing usage of computer and internet applications in our society, this drives the importance for integrated data centre system and cloud computing developments in IT industry. Therefore, the need for the increasing energy consumption in the data centre industry is rising in order to support the high demands in the IT lifestyle that everyone pursue. In both Uninterruptible Power Supply (UPS) and Cooling System, energy inefficiency has been found to contribute up to an estimation of 30% of the total data centre energy consumption. This will be the focus of the study, to characterise the design parameters and determine the effect of the parameters on energy efficiency. Parametric studies have been carried out on generic model and capacity for UPS, cooling plant and system configuration using energy-modelling software. For both systems, the impact on the configured capacity will affect the energy efficiency in data centres. Design parameters correlation with efficiency such as UPS load factor (ULF) and cooling system sizing factor will be analysed in the report. For this study, the Tier configuration will be Tier III. This will provide an in-depth understanding of data centres’ part load efficiency over the entire growth from their initial stage to maximum capacity. It shows huge potential energy saving in designing data centre with the respect to IT load growth plan
