ABSTRACT
This chapter analyzes the energetic and economic performance of the concepts varying the main Data Centre’s characteristics. The energy efficiency strategies are technical solutions that can be applied in almost all the Data Centres and combined with any system to supply cooling and power with or without renewable energy sources. Standard Data Centres have redundant chiller which can be used to produce chilled water when the electricity cost is low during off-peak hours and store that cold in the TES system. Higher costs come from the additional storage systems which do not produce enough savings in energy costs to compensate the additional investment. Also, an increase of primary energy consumption is shown. These results related to concept indicate that it is an advanced technical concept which may have some benefits in specific contexts where high fluctuation of energy prices occurs along the day.
