The smart control strategy on whole data centre energy system including the different power feeding solutions and cooling solutions are considered to get the higher energy efficiency and decrease the whole energy consumption. Firstly, for multiple energy input system, PV, wind, fuel cells, the grid, power generator and batteries were connected to the system. How to control these different energy inputs in smart way to increase the energy efficiency and also decrease the carbon emission will be considered in this Recommendation. In addition, for smart cooling system, how to use the outside cool air and maximize utilization of ICT side cooling such as ICT rack cooling, row cooling methods and liquid cooling etc. This Recommendation focuses on smart energy solutions for data centre to achieve green and sustainable goals including environmental friendly, decreasing carbon emissions, increasing energy efficiency and extending product life etc.
