Abstract
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)听听听 defines the CER of a DC;
b)听听听 describes the relationship of this KPI to a DC鈥檚 infrastructure, information technology equipment and information technology operations;
c)听听听 defines the measurement, the calculation and the reporting of the parameter; and
d)听听听 provides information on the correct interpretation of the CER.
础苍苍别虫听础 describes the correlation of the CER and other KPIs.
础苍苍别虫听叠 provides examples of the usage of the CER.
础苍苍别虫听颁 introduces the parameters that affect the CER.
础苍苍别虫听顿 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).
