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 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 important in order
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 document, the EN 50600 series is designed as a framework of standards,
technical specifications and technical reports covering the design, the operation and management, the key
performance indicators for energy efficient operation of the data centre as well as a data centre maturity model.
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/TS 50600-5 series defines the data centre maturity model requirements and recommendations.
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 documents 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.

95 Introduction
96 The unrestricted access to internet-based information demanded by the information society has led to an
97 exponential growth of both internet traffic and the volume of stored/retrieved data. Data centres are housing
98 and supporting the information technology and network telecommunications equipment for data processing,
99 data storage and data transport. They are required both by network operators (delivering those services to
100 customer premises) and by enterprises within those customer premises.
101 Data centres usually need to provide modular, scalable and flexible facilities and infrastructures to easily
102 accommodate the rapidly changing requirements of the market. In addition, energy consumption of data centres
103 has become critical both from an environmental point of view (reduction of environmental footprint) and with
104 respect to economical considerations (cost of energy) for the data centre operator.
105 The implementation of data centres varies in terms of:
106 a) purpose (enterprise, co-location, co-hosting or network operator facilities);
107 b) security level;
108 c) physical size;
109 d) accommodation (mobile, temporary and permanent constructions).
110 The needs of data centres also vary in terms of availability of service, the provision of security and the objectives
111 for energy efficiency. These needs and objectives influence the design of data centres in terms of building
112 construction, power distribution, environmental control, telecommunications cabling and physical security as
113 well as the operation of the data centre. Effective management and operational information is imperative in
114 order to monitor achievement of the defined needs and objectives.
115 Recognizing the substantial resource consumption, particularly of energy, of larger data centres, it is also
116 important to provide tools for the assessment of that consumption both in terms of overall value and of source
117 mix and to provide Key Performance Indicators (KPIs) to evaluate trends and drive performance improvements.
118 At the time of publication of this document, the EN 50600 series is designed as a framework of standards and
119 technical reports covering the design, the operation and management as well as the key performance indicators
120 for energy efficient operation of the data centre.
121 The EN 50600-2 series defines the requirements for the data centre design.
122 The EN 50600-3 series defines the requirements for the operation and the management of the data centre.
123 The EN 50600-4 series defines the key performance indicators for the data centre.
124 The CLC/TR 50600-99-X Technical Reports cover recommended practices and guidance for specific topics
125 around data centre operation and design.
126 This series of European Standards specifies requirements and recommendations to support the various parties
127 involved in the design, planning, procurement, integration, installation, operation and maintenance of facilities
128 and infrastructures within data centres. These parties include:
129 1) owners, operators, facility managers, ICT managers, project managers, main contractors;
130 2) consulting engineers, architects, building designers and builders, system and installation designers,
131 auditors, test and commissioning agents;
132 3) facility and infrastructure integrators, suppliers of equipment;
133 4) installers, maintainers.
134 At the time of publication of this document, the EN 50600-2 series comprises the following standards:
135 EN 50600-2-1: Information technology — Data centre facilities and infrastructures — Part 2-1: Building
136 construction;

147 Figure 1 — Schematic relationship between the EN 50600 series standards
148 EN 50600-2-X standards specify requirements and recommendations for particular facilities and infrastructures
149 to support the relevant classification for “availability”, “physical security” and “energy efficiency enablement”
150 selected from EN 50600-1.
151 EN 50600-3-X documents specify requirements and recommendations for data centre operations, processes
152 and management.
153 EN 50600-4-X documents specify requirements and recommendations for key performance indicators (KPIs)
154 used to assess and improve the resource usage efficiency and effectiveness, respectively, of a data centre.
155 This document addresses the building design of data centres; it addresses security issues from a constructional
156 point of view, whereas EN 50600-2-5 specifies the security system requirements of those facilities and
157 infrastructures (in accordance with the requirements of EN 50600-1).
158 This document is intended for use by and collaboration between architects, building designers and builders,
159 system and installation designers.
160 This series does not address the selection of information technology and network telecommunications
161 equipment, software and associated configuration issues.
