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

Part 2:
Definitions and descriptions
AMENDMENT 1: Key performance indicators for energy
management
Introduction
Add the following paragraph and new Figure 3 at the end of the Introduction. Renumber Figures 3 to 5
as Figures 4 to 6.
KPIs for energy management within MOM are in accordance with ISO 50001 and ISO 20140, and they
complement MOM indicators regarding energy consumption. KPIs for energy management support the
evaluation of direct energy consumption per work unit or per order, and per manufactured product
item. Figure 3 illustrates the approach and the focus in the determination of energy consumption.

Clause 2, Terms and definitions
Add the following term and definition:
2.5
direct energy consumption
energy consumed by the work unit during the actual unit busy time
Note 1 to entry The concept of “direct energy consumption” in ISO 20140-1 represents the energy consumed by
a work unit for a direct operation (as defined in ISO 20140-1:2013, 3.4). ISO 20140 enables an energy efficiency
evaluation quantified by KPIs with a granularity that itemizes the energy consumption per equipment part of
the work unit. The granularity of this part of ISO 22400 does not itemize the work unit energy consumption per
equipment part of the work unit. The difference in the granularity of the KPI and scope between ISO 22400 and
ISO 20140 leads to different, though not contradictory, definitions of the term “direct energy consumption” in the
two standards.
Note 2 to entry If a work centre fulfils the same requirements as a work unit, it can be considered as a work unit.
Note 3 to entry The attribute direct is used for the purpose of consistency with the concept direct cost.
Clause 3, Symbols and abbreviated terms
Add the following abbreviated terms:
ADEC actual direct energy consumption
PDEI planned direct energy consumption per item
Clause 5
Add the following subclauses, including new Figure 7, immediately after 5.7.5:
5.8 Energy elements
5.8.1 Actual direct energy consumption (ADEC)
The actual direct energy consumption is the measured direct energy consumption per work unit and
during actual unit busy time.
5.8.2 Planned direct energy consumption per item (PDEI)
The planned direct energy consumption shall be the planned energy consumption in average for
producing one product item.
NOTE This factor is analogous to the planned run time per item.
5.8.3 Time period
A time period is the time during which a work unit is in a specific state. With each change of state a new
time period always begins.
5.8.4 Fundamentals of energy types
5.8.4.1 Conversion to a unified energy unit
Energy measurements are commonly made in various units of energy and shall be converted to the
industry standard, namely, kWh, as illustrated in Figure 7. This conversion is necessary to obtain a valid
summation of the different expressions of energy usage for computing the direct energy consumption.
For this purpose, conversion factors depending on the type of energy need to be determined.

5.8.4.2 Conversion factors
5.8.4.2.1 Conversion factors provided by energy suppliers
Conversion factors for energy types are usually obtained directly from an energy supplier. These
conversions introduce measurement uncertainties from a number of different sources, which should be
understood and incorporated in calculations.
