EN 50600-1:2019 (E)
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 usually 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 environmental
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, telecommunications cabling and
physical security as well as the operation of the data centre. Effective management and operational
information is required to monitor achievement of the defined needs and objectives.
Recognizing the substantial resource consumption, particularly of energy, of larger data centres, it is also
important to provide tools for the assessment of that consumption both in terms of overall value and of
source mix and to provide Key Performance Indicators (KPIs) to evaluate trends and drive performance
improvements.
At the time of publication of this European Standard, EN 50600 series is designed as a framework of
standards and technical reports covering the design, the operation and management as well as the key
performance indicators for energy efficient operation of the data centre.
The EN 50600-2 series defines the requirements for the data centre design.
The EN 50600-3 series defines the requirements for the operation and the management of the data
centre.
The EN 50600-4 series defines the key performance indicators for the data centre.
The CLC/TR 50600-99-X Technical Reports cover recommended practices and guidance for specific
topics around data centre operation and design.
This series of European Standards 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, operators, facility managers, ICT managers, project managers, main contractors;
2) consulting engineers, architects, building designers and builders, system and installation designers,
auditors, test and commissioning agents;
3) facility and infrastructure integrators, suppliers of equipment;
4) installers, maintainers.

The inter-relationship of the standards and technical reports within the EN 50600 series is shown in
Figure 1.

Figure 1 – Schematic relationship between EN 50600 series of standards
This European Standard specifies general requirements for data centres for all kinds of data centres
irrespective of their size and physical construction. It introduces a classification system for availability,
physical security and energy efficiency enablement.
EN 50600-2-X standards specify requirements and recommendations for particular facilities and
infrastructures to support the relevant classification for “availability”, “physical security” and “energy
efficiency enablement” selected from EN 50600-1.
EN 50600-3-X documents specify requirements and recommendations for data centre operations,
processes and management.
EN 50600-4-X documents specify requirements and recommendations for key performance indicators
(KPIs) used to assess and improve the resource usage efficiency and effectiveness, respectively, of a
data centre.
This European Standard is intended for use by and collaboration between architects, building designers
and builders, system and installation designers.
This series of European Standards does not address the selection of information technology and network
telecommunications equipment, software and associated configuration issues.

This document:
a) describes the general principles for data centres upon which the requirements of the EN 50600
series are based;
b) defines the common aspects of data centres including terminology, parameters and reference
models (functional elements and their accommodation) addressing both the size and complexity of
their intended purpose;
c) describes general aspects of the facilities and infrastructures required to support data centres;
d) specifies a classification system, based upon the key criteria of “availability”, “security” and “energy-
efficiency” over the planned lifetime of the data centre, for the provision of effective facilities and
infrastructure;
e) details the issues to be addressed in a business risk and operating cost analysis enabling application
of the classification of the data centre;
f) provides reference to operation and management of data centres;
g) introduces the concepts of Key Performance Indicators (KPIs) for resource management of data
centre facilities and infrastructures.
The following topics are outside of the scope of this series of European Standards:
1) the selection of information technology and network telecommunications equipment, software and
associated configuration issues are outside the scope of this European Standard;
2) quantitative analysis of overall service availability resulting from multi-site data centres;
3) safety and electromagnetic compatibility (EMC) requirements (covered by other standards and
regulations. However, information given in this European Standard can be of assistance in meeting
these standards and regulations).
