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.

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) .

3 Terms and definitions
3.1 Terms related to energy
3.1.1
energy
E
capacity of a system to produce external activity or to perform work
Note 1 to entry: Commonly the term energy is used for electricity, fuel, steam, heat, compressed air and other like
media.
Note 2 to entry: Energy is commonly expressed as a scalar quantity.
Note 3 to entry: Work as used in this definition means external supplied or extracted energy to a system. In
mechanical systems, forces in or against direction of movement; in thermal systems, heat supply or heat removal.
[SOURCE: 1986 World Energy Conference Energy Terminology glossary, modified – The word “the” at
the beginning of the description was removed, the symbols were added as was the Note 1 to entry from
ISO 50001:2011.]
3.1.2
energy carrier
substance or medium that can transport energy

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.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
This clause has been maintained to match the numbering of ISO/IEC 13273-2 and for potential future use.
3 Terms and definitions
3.1 Terms related to energy
3.1.1
energy
E
capacity of a system to produce external activity or to perform work
Note 1 to entry: Commonly the term energy is used for electricity, fuel, steam, heat, compressed air and other like
media.
Note 2 to entry: Energy is commonly expressed as a scalar quantity.
Note 3 to entry: Work as used in this definition means external supplied or extracted energy to a system. In
mechanical systems, forces in or against direction of movement; in thermal systems, heat supply or heat removal.
[SOURCE: 1986 World Energy Conference Energy Terminology glossary, modified – The word “the” at
the beginning of the description was removed, the symbols were added as was the Note 1 to entry from
ISO 50001:2011.]
3.1.2
energy carrier
substance or medium that can transport energy
EXAMPLE Electricity, hydrogen, fuels.

3.1.3
feedstock energy
energy (3.1.1) of material used for purposes other than producing work or activity
EXAMPLE Crude oil injected into steel smelting is for deoxidization but it contributes to the energy content
in a limited manner.
Note 1 to entry: Care is necessary to ensure that the energy content of materials is properly accounted for in the
energy balance.
3.1.4
energy source
material, natural resource or technical system from which energy (3.1.1) can be extracted or recovered
Note 1 to entry: A press spring, flywheel, or battery are examples of a technical system used as an energy source.
3.1.5
energy storage
action or method used to accumulate, retain and release energy (3.1.1) for later use in an energy using
system (3.1.9)
Note 1 to entry: Energy storage is an important concept in terms of renewable energy, see ISO/IEC 13273-2, 3.1.5
for additional information.
3.1.6
primary energy
energy (3.1.1) that has not been subjected to energy conversion (3.1.7)
Note 1 to entry: Primary energy can be either a non-renewable or renewable energy or a combination of both.
[SOURCE: ISO 16818-3.177:2008, modified – the word “any” was deleted and the term energy conversion
and reference was added; the phrase “or transformation process” was deleted; Note 1 to entry was added.]
3.1.7
energy conversion
transformation of one energy carrier (3.1.2)-to another energy carrier or work
Note 1 to entry: The term “energy transformation” can be used in this sense.
3.1.8
cogeneration
energy conversion (3.1.7) from the same source into two or more utilized forms of energy in one common
controlled process
Note 1 to entry: Combined heat and power (CHP) is a specific implementation of cogeneration used for the
simultaneous production of heat and electricity.
3.1.9
energy using system
physical items with defined system boundaries (3.3.2), using energy (3.1.1)
EXAMPLE Facility, building, part of a building, machine, equipment, product, etc.
3.1.10
energy end user
individual or a group of individuals or organization with responsibility for operating an energy using
system (3.1.9)
3.1.11
final energy
energy (3.1.1) as delivered to an energy using system (3.1.9)
Note 1 to entry: This concept is sometimes referred to as delivered energy.
