Energy performance of lifts, escalators and moving walks - Part 3: Energy calculation and classification of escalators and moving walks (ISO 25745-3:2015)

ISO 25745-3:2015 specifies generic tools for estimating energy consumption of escalators and moving walks, and a consistent method for energy performance classification of existing, modernized, or new escalators and moving walks.
It considers the energy performance during the operational portion of the life cycle of escalators and moving walks. It does not cover energy consumption and classification of the ancillary equipment, such as the following:
a) lighting with the exception of comb plate lighting, step gap lighting, and traffic light (comb plate lighting, step gap lighting, and traffic light are considered essential for the operation of the equipment and are therefore not defined as ancillary equipment);
b) cooling and heating and machine room ventilation;
c) alarm devices and emergency battery supplies equipment, etc.;
d) environmental conditions;
e) consumption through the power sockets.
There can be other electrical loads not associated with the escalator or moving walk, and not included.
ISO 25745-3:2015 considers all escalators and inclined moving walks up to a rise of 8 m and horizontal moving walks with a length up to 60 m (this represents about 85 % of worldwide installed units).

Energieeffizienz von Aufzügen, Fahrtreppen und Fahrsteigen - Teil 3: Energieberechnung und Klassifizierung von Fahrtreppen und Fahrsteigen (ISO 25745-3:2015)

Dieser Teil der EN ISO 25745 stellt
a)   allgemeine Hilfsmittel zur Abschätzung des Energieverbrauchs von Fahrtreppen und Fahrsteigen und
b)   eine einheitliche Vorgehensweise zur Klassifizierung der Energieeffizienz von bestehenden, modernisierten oder neuen Fahrtreppen und Fahrsteigen
zur Verfügung.
Dieser Teil von EN ISO 25745 gilt für die Energieeffizienz während des betrieblichen Teils im Lebenszyklus von Fahrtreppen und Fahrsteigen. Sie behandelt nicht den Energieverbrauch und die Klassifizierung von Zusatzverbrauchern wie:
a)   Beleuchtung mit Ausnahme der Kammplattenbeleuchtung, Stufenspaltbeleuchtung und Fahrtrichtungsanzeige;
ANMERKUNG 1      Kammplattenbeleuchtung, Stufenspaltbeleuchtung und Fahrtrichtungsanzeige werden als wesentlich für den Betrieb der Anlage angesehen und daher nicht als Hilfseinrichtungen eingestuft.
b)   Kühlung und Heizung sowie Belüftung des Triebwerksraums;
c)   Alarmeinrichtungen und Versorgung der Notstrombatterien usw.;
d)   Umgebungsbedingungen;
e)   Verbrauch über die Steckdosen.
ANMERKUNG 2   Möglicherweise sind weitere elektrische Verbraucher vorhanden, die nicht im Zusammenhang mit Fahrtreppen und Fahrsteigen stehen und daher nicht aufgenommen werden dürfen.
1Dieser Teil von EN ISO 25745 berücksichtigt alle Fahrtreppen und geneigte Fahrsteige bis zu einer Förderhöhe von 8 m sowie horizontale Fahrsteige bis zu einer Länge von 60 m.
ANMERKUNG   Damit sind etwa 85 % der weltweit eingebauten Anlagen abgedeckt.

Performance énergétique des ascenseurs, escaliers mécaniques et trottoirs roulants - Partie 3: Calcul énergétique et classification des escaliers mécaniques et trottoirs roulants (ISO 25745-3:2015)

L'ISO 25745-3:2015 spécifie des outils génériques pour estimer la consommation énergétique des escaliers mécaniques et trottoirs roulants, et une méthode cohérente de classification de la performance énergétique pour des escaliers mécaniques et trottoirs roulants existants, modernisés ou neufs.
Elle prend en considération la performance énergétique pendant la période opérationnelle du cycle de vie des escaliers mécaniques et trottoirs roulants. Elle ne traite pas de la consommation énergétique et de la classification des équipements auxiliaires, tels que:
a) l'éclairage, à l'exception de l'éclairage des plaques porte-peignes, de l'éclairage des interstices entre les marches et des feux de signalisation (l'éclairage des plaques porte-peignes, l'éclairage des interstices entre les marches et les feux de signalisation sont considérés comme essentiels au fonctionnement de l'équipement; ils ne sont par conséquent pas définis comme équipements auxiliaires);
b) le refroidissement et le chauffage et la ventilation du local de machines;
c) les dispositifs d'alarme et les équipements d'alimentation de secours à batterie, etc.
d) les conditions d'environnement;
e) la consommation par le biais des prises de courant.
Il peut y avoir d'autres charges électriques non associées à l'escalier mécanique ou au trottoir roulant; elles ne doivent pas être incluses.
L'ISO 25745-3:2015 considère que tous les escaliers mécaniques et les trottoirs roulants inclinés s'élèvent jusqu'à 8 m de hauteur, et que les trottoirs roulants horizontaux mesurent jusqu'à 60 m de long (ces caractéristiques représentent environ 85 % des appareils installés dans le monde).

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).

Introduction

This International Standard has been prepared in response to the rapidly increasing need to ensure and

to support the efficient and effective use of energy. This International Standard provides

a) a method to estimate energy consumption of escalators and moving walks on a daily and an annual

basis for escalators and moving walks,

b) a method for energy classification of new, existing, or modernized escalators and moving walks,

c) guidelines for reducing energy consumption that can be used to support building and environmental

and energy classification systems.

This International Standard is intended to be a reference for the following parties:

— building developers/owners to evaluate the energy consumption of escalators and moving walks;

— building owners and service companies when modernising installations including reduction of

energy consumption;
— the installers and maintenance providers of escalators and moving walks;

— consultants and architects involved in specification of escalators and moving walks;

— inspecting authorities and other third parties providing energy classification services.

The total energy consumption over the entire life cycle of escalators and moving walks consists of

the energy to manufacture, install, operate, and dispose of the lifts. However, for the purpose of this

International Standard, only operating energy (running and standby) performance is considered.

In the preparation of this International Standard, Technical Committee ISO/TC 178/ WG 10 has initiated

extensive research, which included the measuring and modelling of over 300 typical escalator and

moving walk installations. The results of this research have been used to provide the numerical values

shown in Table 3 and Table A.3.

This International Standard is suitable for national/regional jurisdictional energy performance

purposes.

Energy performance of lifts, escalators and moving
walks —
Part 3:
Energy calculation and classification of escalators and
moving walks
1 Scope
This part of ISO 25745 specifies

a) generic tools for estimating energy consumption of escalators and moving walks, and

b) a consistent method for energy performance classification of existing, modernized, or new escalators

and moving walks.

This part of ISO 25745 considers the energy performance during the operational portion of the life cycle

of escalators and moving walks. It does not cover energy consumption and classification of the ancillary

equipment, such as the following:

a) lighting with the exception of comb plate lighting, step gap lighting, and traffic light;

NOTE 1 Comb plate lighting, step gap lighting, and traffic light are considered essential for the operation

of the equipment and are therefore not defined as ancillary equipment.
b) cooling and heating and machine room ventilation;
c) alarm devices and emergency battery supplies equipment, etc.;
d) environmental conditions;
e) consumption through the power sockets.

NOTE 2 There can be other electrical loads not associated with the escalator or moving walk, which shall

not be included.

This part of ISO 25745 considers all escalators and inclined moving walks up to a rise of 8 m and

horizontal moving walks with a length up to 60 m.
NOTE This represents about 85 % of worldwide installed units.
2 Normative references
