Summary

Recommendation ITU-T L.1302 specifies an energy efficiency assessment methodology for data centres and telecom centres, test equipment accuracy requirements, assessment period, assessment conditions and calculation methods.

Concerning the data centres and telecom centres, the Recommendation considers assessment methods for the efficiency of the whole data centre/telecom centre and of a part of the data centre/telecom centre.

As the main energy-consuming infrastructure in data centres and telecom centres are the power feeding system (power supply system) and the cooling system, this Recommendation covers energy efficiency measurement methodologies for both types of systems.

The Recommendation takes into account methodologies and best practices currently in use or under development in networks, and data centres and telecom centres.

This Recommendation is aimed at reducing the negative impact of data centres and telecom centres through by providing methodologies for energy efficiency assessment. It is commonly recognized that data centres and telecom centres will have an ever-increasing impact on the environment in the future. The application of the assessment methods defined in this Recommendation can help owners and managers to build future data centres and telecom centres, or improve existing ones, that will operate in an environmentally responsible manner.
