Standards Development
This document specifies the Power Usage Effectiveness (PUE) as a Key Performance Indicator (KPI) to quantify the efficient use of energy in the form of electricity.
This European Standard:
a) defines the Power Usage Effectiveness (PUE) of a data centre;
b) introduces PUE measurement categories;
c) describes the relationship of this KPI to a data centre’s infrastructure, information technology equipment and information technology operations;
d) defines the measurement, the calculation and the reporting of the parameter;
e) provides information on the correct interpretation of the PUE.
Since the 1st edition of the standard in 2016, user feedback has been received and new aspects related to energy efficiency and sustainability of data centres have emerged. Therefore, a revision of the EN is needed.
You are now following this standard. Weekly digest emails will be sent to update you on the following activities:
