In this section, the results of the monitoring campaign are presented as well as a brief
description of the methodology used for the measurements.
5.1 Methodology
For the measurement of the energy consumption of the lifts and escalators audited, and to
ensure the repeatability of the measurements throughout the campaign, a methodology was
developed, based on the following documents:
• Draft International Standard ISO/DIS 25745‐1 Energy Performance of Lifts and
Escalators – Part 1: Energy Measurement and conformance, 2008 [1];
• EN 60359:2002 Electrical and electronic measurement equipment ‐ Expression of the
performance [2];
• Nipkow J. Elekrizitaetsverbrauch und Einspar‐Potenziale bei Aufzuegen, Schlussbericht
November 2005, Im Auftrag des Bundesamtes fuer Energie [3];
• Lindegger Urs, Energy estimation: Document for E4, ELA, VDI & ISO, 11 June 2008 [4];
• Gharibaan Esfandiar, Load Factor for Escalators, EG (09/05/2008) [5].
Only a brief description of the methodology is made in this report, to help readers understand
the basic procedures behind the measurements made. A detailed description of the
methodology can be found on the project’s website (www.e4project.eu).
The aim of the measurements was to determine the direct energy consumption of the
installation itself – in the case of a lift this includes the direct electrical power consumption of
