CSA Preface Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T). Scope This part of ISO/IEC 30134 specifies the power usage effectiveness (PUE) as a key performance indicator (KPI) to quantify the efficient use of energy in the form of electricity. This part of ISO/IEC 30134 a) defines the power usage effectiveness (PUE) of a data centre b) introduces PUE measurement categories c) describes the relationship of this KPI to a data centre’s infrastructure, information technology equipment and information technology operations d) defines the measurement, the calculation and the reporting of the parameter e) provides information on the correct interpretation of the PUE. PUE derivatives are described in Annex D.
