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.
At the time of publication of this document, the EN 50600-2 series comprises the following documents:
EN 50600-2-1, Information technology — Data centre facilities and infrastructures — Part 2-1: Building
construction;
EN 50600-2-2, Information technology — Data centre facilities and infrastructures — Part 2-2: Power supply

Figure 1 — Schematic relationship between the EN 50600 series standards
EN 50600-2-X documents 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 document addresses the site selection and the building design of data centres; it addresses security issues
from a constructional point of view, whereas EN 50600-2-5 specifies the security system requirements of those
facilities and infrastructures (in accordance with the requirements of EN 50600-1).
This document is intended for use by and collaboration between architects, building designers and builders,
system and installation designers.
This series of documents does not address the selection of information technology and network
telecommunications equipment, software and associated configuration issues.

For information on the designation of spaces within the data centre building regarding their Protection Classes,
see EN 50600-2-5.
6.2 Site selection
6.2.1 Requirements
The size and shape of a new site shall be suitable to accommodate the intended functions.
A site survey shall be commissioned to include both surface and geotechnical aspects. The results of the survey
shall be relevant (i.e. based on current information).
The geotechnical survey shall include the following which would influence the construction and operation of the
data centre:
a) safe load bearing capacity;
b) buried cavities (natural or man-made) and buried utility infrastructures;
c) measurements, and expected variations of, soil resistivity and ground water conditions;
d) presence of contamination;

to be assessed.
A composite utilities plan showing all underground and above ground utilities shall be provided (see
EN 50600-3-1).
6.4.3 Recommendations
Recommendations for the selection of pathways for electricity supply are provided in EN 50600-2-2.
In general, where under control of the premises owner, the pathways within the premises should be located
underground unless the risk from accidental excavation is considered higher than the threat from atmospheric
disturbance or deliberate or accidental physical damage.
Redundant pathways for the same utility serving the data centre, other than those of 6.4.1, should be physically
separated between the boundary of the premises and the point of entry into buildings to ensure that a single
incident will not cause damage to both paths and entrance facilities. Any additional distance of separation
between pathways of different utilities should be based upon risk analysis.

EN 50600-2-5 specifies Protection Classes for the areas surrounding the data centre spaces. Requirements
and recommendations for each Protection Class (and the boundaries between them) are specified in
EN 50600-2-5. The following subclauses specify the relevant constructional requirements and
recommendations of boundaries of these areas in outside spaces with reference to the Protection Class of
EN 50600-2-5. Requirements and recommendations regarding co-location of boundaries are given in
EN 50600-2-5.
Subclause 8.4 contains requirements for all materials used to construct the boundaries of spaces of a given
Protection Class. These are based on a minimum time of intrusion resistance using a specified set of tools as
defined in the Resistance Classes of EN 1627.
The following minimum times of intrusion resistance are applicable:
a) Resistance Class 2: 3 min.;
b) Resistance Class 3: 5 min.;
c) Resistance Class 4: 10 min.
The times shall be taken into account in the design of the response system following identification of a potential
intruder (see 8.4 for interior protection class boundaries).
This document applies those requirements to materials other than those included within the scope of EN 1627.
NOTE There are a number of internationally recognized assessment and audit schemes which extend the principles
of EN 1627 to other constructional elements including walls, roofs, gates and free-standing barriers.
The need for visual or acoustic screening of the data centre perimeters, exterior installations or individual
exterior data centre areas should be assessed.
The number of penetrations of the external physical barriers of Protection Classes should be minimized.
External areas should be maintained and buffer zones created to minimize disturbance to or by neighbours.
7.6.2 Free-standing barriers
The minimum effective height (h ) of free-standing barriers is specified in Table 1. Table 1 also contains
e
requirements for the height to which optimum penetration resistance is provided.
