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. 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 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).
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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
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 the following

This document was prepared by Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 39, Sustainability for and by Information Technology.

Introduction
The unrestricted access to internet-based information demanded by the information society has led to
an exponential growth of both internet traffic and the volume of stored/retrieved data. Data centres
are housing and supporting the information technology and network telecommunications equipment
for data processing, data storage and data transport. They are required both by network operators
(delivering those services to customer premises) and by enterprises within those customer premises.
Data centres need to provide modular, scalable and flexible facilities and infrastructures to easily
accommodate the rapidly changing requirements of the market. In addition, energy consumption of data
centres has become critical both from an environmental point of view (reduction of carbon footprint)
and with respect to economical considerations (cost of energy) for the data centre operator.
The implementation of data centres varies in terms of:
a) purpose (enterprise, co-location, co-hosting or network operator facilities);
b) security level;
c) physical size;
d) accommodation (mobile, temporary and permanent constructions).
The needs of data centres also vary in terms of availability of service, the provision of security and
the objectives for energy efficiency. These needs and objectives influence the design of data centres
in terms of building construction, power distribution, environmental control and physical security.
Effective management and operational information is required to monitor achievement of the defined
needs and objectives.
The ISO/IEC TS 22237 series specifies requirements and recommendations to support the various
parties involved in the design, planning, procurement, integration, installation, operation and
maintenance of facilities and infrastructures within data centres. These parties include:
1) owners, facility managers, ICT managers, project managers, main contractors;
2) consultants, architects, building designers and builders, system and installation designers;
3) suppliers of equipment;
4) installers, maintainers.
At the time of publication of this document, the ISO/IEC TS 22237 series will comprise the following
documents:
— ISO/IEC TS 22237-1, Information technology — Data centre facilities and infrastructures — Part 1:
General concepts;
— ISO/IEC TS 22237-2, Information technology — Data centre facilities and infrastructures — Part 2:
Building construction;
— ISO/IEC TS 22237-3, Information technology — Data centre facilities and infrastructures — Part 3:
Power distribution;
— ISO/IEC TS 22237-4, Information technology — Data centre facilities and infrastructures — Part 4:
Environmental control;
— ISO/IEC TS 22237-5, Information technology — Data centre facilities and infrastructures — Part 5:
Telecommunications cabling infrastructure;
— ISO/IEC TS 22237-6, Information technology — Data centre facilities and infrastructures — Part 6:

Management and operational information.
The inter-relationship of the specifications within the ISO/IEC TS 22237 series is shown in Figure 1.
Figure 1 — Schematic relationship between the ISO/IEC TS 22237 series of documents
This document, defines the general concepts for the design and operation of data centres. This includes
a business risk and operational cost analysis as well as a classification system for data centres with
respect to “availability”, “physical security” and “energy efficiency enablement”.
ISO/IEC TS 22237-2 to ISO/IEC TS 22237-7 specify requirements and recommendations for particular
facilities and infrastructures to support the relevant classification for “availability”, “physical security”
and “energy efficiency enablement” selected from ISO/IEC TS 22237-1.
ISO/IEC TS 22237-7 addresses the operational and management information (in accordance with the
requirements of ISO/IEC TS 22237-1).
This document is intended for use by and collaboration between architects, building designers and
builders, system and installation designers.
The ISO/IEC TS 22237 series does not address the selection of information technology and network
telecommunications equipment, software and associated configuration issues.

Information technology — Data centre facilities and
infrastructures —
Part 1:
General concepts
1 Scope
This document:
a) details the issues to be addressed in a business risk and operating cost analysis enabling application
of an appropriate classification of the data centre;
