National bodies that are members of ISO or IEC participate in the development of International St

12、andards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO a

13、nd IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particu

20、ration, transmission, dissemination, computation and storage of digital data. All markets have experienced exponential growth in that data, for social, educational and business sectors and, while the internet backbone carries the traffic, there are a wide variety of data centres at nodes and hubs wi

21、thin both private enterprise and shared/collocation facilities. The historical data generation growth rate exceeds the capacity growth rate of the information and communications technology hardware and, with less than half (in 2014) of the worlds population having access to an internet connection, t

22、hat growth in data can only accelerate. In addition, with many governments having “digital agendas” to provide both citizens and businesses with ever-faster broadband access, the very increase in network speed and capacity will, by itself, generate ever more usage (Jevons Paradox). Data generation a

23、nd the consequential increase in data manipulation and storage are directly linked to increasing power consumption. With this background, it is clear that data centre growth, and power consumption in particular, is an inevitable consequence and that growth will demand increasing power consumption de

24、spite the most stringent energy efficiency strategies. This makes the need for key performance indicators (KPIs) that cover the effective use of resources (including but not limited to energy) and the reduction of CO 2emissions essential. Within the ISO/IEC 30134 series, the term “resource usage eff

25、ectiveness” is more generally used for KPIs in preference to “resource usage efficiency”, which is restricted to situations where the input and output parameters used to define the KPI have the same units. In order to determine the overall resource effectiveness or efficiency of a data centre, a hol

26、istic suite of metrics is required. This part of ISO/IEC 30134 specifies the renewable energy factor (REF) which provides a quantitative metric for the actual use of renewable energy (RE) in the form of electricity in a data centre. NOTE This part of ISO/IEC 30134 adopts the ISO/IEC definition of RE

27、 but defers to the definition that apply within local jurisdiction(s). The use of and the demand for RE became increasingly popular as it reduces or replaces the use of non-RE sources. In many countries, legislation promotes the use of RE and gives incentives in order to increase the diversity of en

28、ergy dependence and improve social sustainability. In several countries, governments have targets for the use of RE and/or companies have a target for the use of RE among all electricity consumed. The use of RE as one of the sources to power data centre becomes increasingly important as their electr

29、icity consumption has risen to a significant share of the total global electricity consumption. The use of REF as a key performance indicator (KPI) allows data centre managers to improve a data centres energy procurement portfolio and increase the diversity of energy dependence. Data centre managers

30、 can confirm their achievement of the use of RE to their national or corporate targets. This part of ISO/IEC 30134 is part of a series of International Standards for such KPIs and has been produced in accordance with ISO/IEC 30134-1, which defines common requirements for a holistic suite of KPIs for

31、 data centre resource usage effectiveness or efficiency. The ISO/IEC 30134 series do not specify limits or targets for any KPI and do not describe or imply, unless specifically stated, any form of aggregation of individual KPIs into a combined nor an overall KPI for data centre resource usage effect

32、iveness or efficiency.

45、of renewable energy factor (REF) REF is defined as the ratio of renewable energy (RE) used in comparison with the total data centre energy consumption as shown in Formula (1): = (1) where E ren is the RE in kWh owned and controlled by a data centre (i.e. any energy for which the data centre owns the

46、 legal right to the environmental attributes of renewable generation) including that a) generated on-site of the data centre and whose legal rights to the environmental attributes of RE are retired in a data centre (so, that is no longer a contractual instrument to be traded, or that is no longer a

47、possession of the last owner or the renewable energy certificate system administrator); NOTE 1 “Retired” is an official term that means “consumed”. b) obtained by procurement of RE certificates and retired in the data centre; c) portion of utility electricity, defined as RE, provided the data centre

48、 has obtained documented written evidence from the source utility provider(s) that the energy supplied, for the reporting period in question, was generated from a renewable source;NOTE 2 This excludes RE generated in a data centre site but whose legal rights to the environmental attributes of RE wer

49、e sold to other parties or the market. E DC is the total data centre energy consumption (annual) in kWh. REF shall have a maximum value of 1,00, indicating 100 % of the total data centre energy is RE. On-site generation of RE beyond the need of the data centre shall not be accounted for REF. Therefore, a value greater than 1,00 is not possible. Because the RE content of the KPI is based on legal ownership of the rights to the environmental benefits, it is
