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.
