Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards 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 and IEC, also take part in the
work.
The procedures used to develop this document and those intended for its further maintenance
are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria
needed for the different types of document should be noted. This document was drafted in
accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives or
www.iec.ch/members_experts/refdocs).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents) or the IEC
list of patent declarations received (see https://patents.iec.ch).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see

Introduction
Data centres are essential to the provision of information technology (IT) services and can play an
important role in the conservation of resources. However, they can also consume a considerable amount
of resources if mis-managed and thus, it is critical to utilize these resources efficiently.
Resource efficiency in a data centre begins with the location (taking advantage of the external
environment) and the building design to minimize energy consumption. The facilities can then
implement modular extension or easily extensible space, cooling, and power according to the IT services
provided and co-location situation.
Once data centres are constructed and equipped with all the necessary facilities, it is important to
collect and monitor operational data. Based on the information obtained, it is possible to determine
which elements utilize resources least efficiently and assess how to improve the performance.
The performance of existing facilities can be periodically measured to determine if the original design
objectives for resource efficiency are being achieved and allowing performance to be improved by
replacement of equipment with better resource-efficiency characteristics.
This document provides information on available options for improving resource efficiency in data
centres, with particular emphasis on operational procedures.

TECHNICAL REPORT ISO/IEC TR 30133:2023(E)
Information technology — Data centres — Practices for
resource-efficient data centres
1 Scope
This document describes generally applicable practices for improving the resource efficiency of data
centres, independent of their application(s).
This document focuses on continuous improvement processes, designs and guidelines that prioritize
resource efficiency. In general, the processes and practices are technology-neutral and are independent
of location.
The practices for data centre resource efficiency improvement deal with various establishment and
operation aspects such as data centre planning, management, cooling, power feeding, information
and communications technology (ICT) and cost aspects that are not restricted by the scope of this
document.
The following items are not included in the scope of this document:
— development of key performance indicators (KPIs);
— comparability between data centre performance results;
— definition of maturity model for data centres;
— social sustainability issues.
