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

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

Figure 1 — Schematic relationship between the EN 50600 series of documents
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 Technical Report is a compilation of recommended practices for improving the environmental
sustainability of data centres.
This document considers that environmental sustainability of a data centre comprises three key areas:
— energy use;
— embodied impact of information and communication technology (ICT) equipment and mechanical
and electrical systems;
— source energy mix of the above (i.e. amount of renewable content).
The recommended practices for improving the environmental sustainability of data centres relating to
operational energy use of a data centre (i.e. reductions of energy consumption and/or improvements of
energy efficiency, re-use of energy and use of renewable energy) are detailed in CLC/TR 50600-99-1.
However, any recommendations of CLC/TR 50600-99-1 that have applicability beyond energy
management and concern environmental sustainability will be included in this document. The long-term
objective is to avoid unintentional duplication of recommended practices in the two documents.
This document provides recommended practices to:
• assess and implement improvements to the environmental sustainability in data centres, by
means of Life Cycle Assessment (LCA);
• assist the industry in taking steps towards more sustainable behaviour.
Customers or suppliers of information and communication technology (ICT) services possibly 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 the 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.
1 Scope
This document is a compilation of recommended practices for improving the environmental
sustainability of both new and existing data centres. Environmental impacts consider not just those
associated with electricity but also water usage and other pollutants.
It is recognised that the practices included are not universally applicable to all scales and business
models of data centres or be undertaken by all parties involved in data centre operation, ownership or
use.
