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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

Introduction
The aim of this part of ISO/IEC 13273 is to support activities related to energy and that deal with
energy efficiency. The terms were selected based upon their relevance and transverse nature. This
International Standard is a horizontal standard in accordance with IEC Guide 108. It addresses the
fundamental principles and concepts of energy efficiency and energy management terminology, which
is relevant to a number of technical committees, with the goal of improving coherence and common
characteristics for energy terms. This International Standard does not address terms specific to topics
such as environmental sustainability or nuclear energy but rather transverse energy terminology.
It is intended to be of help to technical practitioners and other interested parties who either use or
develop International Standards in these subject fields.
With the growth in the number of International Standards that directly or indirectly relate to energy,
there is an increasing need for an agreement on common language in the domain.
Figure 1 — Vocabulary structure
This part of ISO/IEC 13273 deals with concepts belonging to the general subject field of energy and,
within that, transverse concepts in the field of energy efficiency. For renewable energy sources see
ISO/IEC 13273-2.
The arrangement of terms and definitions in this International Standard is based upon concept systems
that show corresponding relationships among energy efficiency and renewable energy sources concepts
(see Figures A.4 to A.8 for additional diagrams on each group of terms). This arrangement provides
users with a structured view of transverse energy concepts and facilitates their understanding. This
terminology promotes a common understanding among all parties involved in energy efficiency and
facilitates effective communication. This part of ISO/IEC 13273 includes terms and definitions that
are commonly used in energy efficiency. The organization of terms is illustrated in Figure 1. This
International Standard is a first effort in the development of a complete set of terms related to energy,
and will be updated as further terms and definitions are agreed upon. (See Clause A.3, Figure A.4) .

Part 1:
Energy efficiency
1 Scope
This part of ISO/IEC 13273 contains transverse concepts and their definitions in the subject field of
energy efficiency. This horizontal standard is primarily intended for use by technical committees in the
preparation of standards in accordance with the principles laid down in IEC Guide 108.
One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal
standards in the preparation of its publications. The contents of this horizontal standard will not apply
unless specifically referred to or included in the relevant publications.
