Published By | Publication Date | Number of Pages |
BSI | 2020 | 22 |
This document specifies the Cooling Efficiency Ratio (CER) as a Key Performance Indicator (KPI) to quantify the efficient use of energy to control the temperature of the spaces within the data centre.
This document:
-
defines the Cooling Efficiency Ratio (CER) of a data centre;
-
describes the relationship of this KPI to a data centre’s infrastructure, information technology equipment and information technology operations;
-
defines the measurement, the calculation and the reporting of the parameter;
-
provides information on the correct interpretation of the CER.
Annex A describes the correlation of CER and other KPIs.
Annex B provides examples of the application of CER.
Annex C introduces the parameters that affect CER.
Annex D describes requirements and recommendations for derivatives of KPIs associated with CER.
