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 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, 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.
At the time of publication of this Technical Report, EN 50600 series will comprise the following
standards and documents:

concepts;

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.
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.

Customers or suppliers of information and communication technology (ICT) services might also find it
useful to request or provide a list of the Practices of this Technical Report that are implemented in a
data centre to assist in procurement of services that meet their environmental or sustainability
standards.
This Technical Report also:
— acts as an education and reference document to assist data centre operators in identifying and
implementing measures to improve the energy management of their data centres;
— provides a common terminology and frame of reference for describing an energy management
practice, avoiding doubt or confusion over terminology.

4 Principles
4.1 General
Clauses 5 to 7 contain the full list of energy management Practices of this Technical Report.
Clause 5 contains those Practices that are considered “Expected Practices” of the CoC and which are
listed under the following situations:
a) existing data centres (example);
b) ICT equipment (new or replacement);
c) software install or upgrade;
d) new build or refurbishment of data centres.
Clause 6 contains those Practices that are considered as optional or alternative. within the CoC
scheme.
Under each heading the recommended Practices of Clauses 5 and 6 are based upon the categories
described in 4.2 to 4.8.
Each practice has been assigned a qualitative value (1 to 5) to indicate the level of benefit to be
expected from its implementation and, therefore, the relative priorities that should be applied to it. A
value of 5 indicates the greatest benefit/priority.
These values are not intended to be totalled or aggregated to provide an overall ‘operator score’ and
should not be mistaken as being quantitative. This would require large scale data on the effects of
each practice or technology which is not yet available as well as a complex system of scoring
representing the combinational increase or reduction of individual practice values within that specific
facility.
Practices under consideration for inclusion in either Clauses 5 or 6 for the next or future
revision/amendment of this Technical Report are included in Clause 7. These Practices do not have a
qualitative value applied to them.
4.2 Data centre utilization, management and planning
It is important to develop a holistic strategy and management approach to the data centre in order to
ensure the required availability and effective delivery of economic and environmental benefits. The
sub-headings under this category are:
a) General policies:
These policies apply to all aspects of the data centre and its operation.
b) Resilience level and provisioning:
Two of the most significant sources of inefficiency in data centres are the over provisioning of
space, power or cooling or the facilities being run at less than full capacity. Monolithic, as opposed
to modular design of facilities also represents a significant and frequently unnecessary capital
expenditure. Further, as the level of resilience of the data centre increases the inefficiencies due
to fixed overheads increase and this is compounded by poor utilization.
c) Involvement of organizational groups:
Ineffective communication between the disciplines working in the data centre is a major driver of
inefficiency and can create issues of capacity management and reliability.

CLC/TR 50600-99-1:2017
4.3 Data centre ICT equipment and services
The ICT equipment creates the demand for power and cooling in the data centre, any reductions in
power and cooling used by, or provisioned for, the ICT equipment will have magnified effects at the
utility energy supply.
The specifications of ICT equipment operating temperature and humidity ranges in this section do not
indicate that the computer room should be immediately operated at the upper bound of these ranges.
This is addressed under the category “Data centre cooling”. The purpose of the equipment
environmental specifications in subclause 4.3 is to ensure that new equipment is capable of operating
under the wider ranges of temperature and humidity thus allowing greater flexibility in operating
temperature and humidity to the operator.
The sub-headings under this category are:
a) Selection and deployment of new ICT equipment:
Once ICT equipment is purchased and installed in the data centre it typically spends several years
in the data centre consuming power and creating heat. The appropriate selection of hardware and
deployment methods can provide significant long term savings.
b) Deployment of new ICT services:
The service architecture, software and deployment of ICT services have an impact at least as
great as that of the ICT equipment.
c) Management of existing ICT equipment and services:
It is common to focus on new services and equipment being installed into the data centre but there
are also
