|Publication Date:||1 May 2019|

a) specifies the Energy Reuse Factor (ERF) as a KPI to quantify the reuse of the energy consumed in the data centre;
b) defines the measurement, the calculation and the reporting of ERF;
c) describes the application of ERF and its discrimination from Power Usage Effectiveness (PUE).
The ERF does reflect the efficiency of the reuse process, which is not part of the data centre.
