1.1 General
This part of ISO 25745 specifies:
a) methods of measuring actual energy consumption of lifts, escalators and moving walks on a single unit basis;
b) methods of carrying out periodic energy verification checks on lifts, escalators and moving walks in operation.
This part of ISO 25745 only considers the energy performance during the operational portion of the life cycle of the lifts, escalators or moving walks.
1.2 Lifts
For lifts, this part of ISO 25745 does not cover energy aspects, such as:
a) hoistway lighting;
d) heating and cooling equipment, including fans in the lift car;
e) machine room lighting;
f) machine room heating, ventilation and air conditioning;
g) non-lift, display systems, closed circuit television security cameras, etc.;
h) non-lift, monitoring systems (building management systems, etc.);
i) the effect of lift group dispatching on energy consumption;
j) non-lift equipment [3.13] consumption through the power sockets.
k) energy storage systems if used as an alternative energy source for operation.
1.3 Escalators and moving walks
For escalators and moving walks, this part of ISO 25745 does not cover energy aspects of the ancillary equipment, such as:
a) lighting with the exception of comb plate lighting and step gap lighting and traffic light;
b) cooling and heating;
c) alarm devices and emergency battery supplies equipment, etc.

This document specifies the additional or deviating requirements to prEN 81-20 for new passenger and goods passenger lifts, which may be used to support faster evacuation of persons with difficulty in using stairs including in case of fire alarm.
This document does not apply to:
— lifts which are not included in a fire resisting building structure;
— the evacuation due to other circumstances, like explosion, chemical or biological attack, flooding, storm damage, earthquake etc.
NOTE General evacuation guidance can be found in ISO/TS 18870.
The following significant hazards are not covered in this document and are assumed to be addressed by the building designer:
— fire or smoke in the evacuation lift well, safe areas or machinery spaces;
— ingress of water to the lift well during evacuation process;
— insufficient or incorrectly located evacuation lifts;
— entrapment in waiting area (safe area) due to absence of lift service or adjacent stairs;
— structural collapse or failure of building services (e.g. power supply, lighting, ventilation) before the evacuation using lifts has been completed;
— presence of harmful gases, potentially explosive atmosphere, extreme climate conditions, transport of dangerous goods, etc.
