Information technology — Data centres key performance indicators — Part 6: Energy Reuse Factor (ERF) ISO/IEC AWI 30134-6

Scope

This document specifies the energy reuse factor (ERF) as a KPI to quantify the reuse of the energy consumed in a data centre. ERF is defined as the ratio of energy being reused divided by the sum of all energy consumed in a data centre. The ERF does reflect the efficiency of the reuse process; the reuse process is not part of a data centre.
