BS EN 50600-4-6:2020

This standard BS EN 50600-4-6:2020 Information technology. Data centre facilities and infrastructures is classified in these ICS categories:

• 35.020 Information technology (IT) in general
• 35.110 Networking
• 35.160 Microprocessor systems

This document:

1. specifies the Energy Reuse Factor (ERF) as a KPI to quantify the reuse of the energy consumed in the data centre;

2. defines the measurement, the calculation and the reporting of ERF;

3. 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.
