European foreword
This document (CLC/TR 50600-99-1:2019) has been prepared by CLC/TC 215 “Electrotechnical
aspects of telecommunication equipment” in conjunction with the Directorate-General Joint Research
Centre (DG JRC) of the European Commission (EC).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CLC/TR 50600-99-1:2018.
CLC/TR 50600-99-1:2018:
— by updating to recently agreed energy management practices and aligns with the 2019 edition of
the EU Code of Conduct for data centres Best Practices document.
— Environmental Sustainability practices incorporated within the 2019 edition of the EU Code of
Conduct for data centres Best Practices document have now been re-located to
CLC/TR 50600-99-2:2019.
This document aligns with the Best Practices document of the Code of Conduct for Data Centre
Energy Efficiency (CoC) scheme operated by the DG JRC and continues to be prepared by data centre
experts from operators, vendors, consultants, academics, professional and national bodies.
The publication of this Technical Report is intended to integrate recommended Practices of energy
management into the EN 50600 series developed by CLC/TC 215.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association.
Regarding the structure of the EN 50600 series, see the Introduction.
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 economic 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.
This 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) architects, consultants, building designers and builders, system and installation designers;
3) facility and infrastructure integrators, suppliers of equipment;
4) installers, maintainers.

Guidance to the application of EN 50600 series.
The inter-relationship of the documents within the EN 50600 series is shown in Figure 1.

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.
The Directorate-General Joint Research Centre (DG JRC) of the European Commission operates a
Code of Conduct for Data Centre Energy Efficiency (CoC) scheme. In support of the scheme, a “best
practices” document has been established by DG JRC. To enhance the visibility, these Best Practices
have been converted in this Technical Report to create recommended Practices for improving the
energy management (i.e. reduction of energy consumption and/or increases in energy efficiency) of
data centres.
The areas addressed are:
— physical building;
— mechanical and electrical equipment;
— computer room;
— cabinets/racks;
— ICT equipment;
— operating systems;
— virtualizat
