ISO 30134:2023 Information technology – Data centres key performance indicators – Part 7: Cooling efficiency ratio (CER)
CDN $173.00
Description
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.
Annex C introduces the parameters that affect the CER.
Annex D describes requirements and recommendations for derivatives of KPIs associated with the CER.
This document is not applicable to cooling systems that are not powered by electricity (e.g. heat-driven absorption chillers).

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.
Annex C introduces the parameters that affect the CER.
Annex D describes requirements and recommendations for derivatives of KPIs associated with the CER.
This document is not applicable to cooling systems that are not powered by electricity (e.g. heat-driven absorption chillers).
