Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction
0.1 General
It is important to engage all types of organizations and, in particular, small and medium-sized
organizations (SMOs) into the broad scale implementation of energy management because of the
significant potential such organizations have for energy performance improvement, associated energy
cost savings and reductions in greenhouse gas (GHG) emissions.
This document is intended to enable organizations to initiate and improve energy management
practices by following a systematic approach with appropriate effort given their resources and context,
resulting in continual energy performance improvement.
This document provides practical guidance to undertake a phased implementation of an energy
management system (EnMS), e.g. by using in-house capacity. The functioning EnMS can subsequently
be extended to meet the
