This document specifies the cooling efficiency ratio (CER) as a key performance indicator (KPI) for quantifying the efficient use of energy to control the temperature of spaces within a data centre (DC).
This document:
a) defines the CER of a DC;
b) describes the relationship of this KPI to a DC.s infrastructure, information technology equipment and information technology operations;
c) defines the measurement, the calculation and the reporting of the parameter; and
d) provides information on the correct interpretation of the CER.
Annex A describes the correlation of the CER and other KPIs.
Annex B provides examples of the usage of the CER.
