Summary

Recommendation ITU-T L.1381 considers a smart control strategy for the entire energy system, including power-feeding and cooling solutions, of data centres to achieve higher energy efficiency and to decrease overall energy consumption.

Firstly, for a multiple energy input system, including photovoltaic (PV) solar panels, wind, fuel cells, the electrical grid, power generators and batteries, can be connected to a system. Recommendation ITU-T L.1381 considers how to control these different energy inputs in a smart way to increase energy efficiency and to decrease carbon emissions. In addition, for smart cooling systems, Recommendation ITU-T L.1381 considers how to use outside cool air and maximize utilization of information and communication technology (ICT) side cooling, e.g., ICT rack cooling, row cooling methods and liquid cooling.

Recommendation ITU-T L.1381 focuses on smart energy solutions for data centres to achieve green and sustainable goals, including those which are environmentally friendly, decrease carbon emissions, increase energy efficiency and extend product life.
