scope:

1.1 This standard 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; c) tools to estimate the energy consumption of lifts, escalators and moving walks for a given building. NOTE These tools may not be accurate for less common lifts, escalators and moving walks at higher speed and load duties; for these cases manufacturers should be consulted. There is no intent that the provided tools will in all cases closely match the actual energy usage as measured in a). 1.2 This standard only considers the energy performance during the operational portion of the life cycle of the lifts, escalators or moving walks 1.3 For lifts this Standard does not cover energy aspects, such as: a) hoistway lighting; b) heating and cooling equipment in the lift car; c) machine room lighting; d) machine room heating, ventilation and air conditioning; e) non -lift, -escalator or -moving walk display systems, CCTV security cameras, etc.; f) non -lift, -escalator or -moving walk monitoring systems (eg: building management systems, etc.); g) input power harmonics (harmonics are addressed in the EMC standards); h) the effect of lift group dispatching on energy consumption; i) environmental conditions. 1.4 For escalators and moving walks this standard does cover energy aspects of the ancillary equipment, such as: a) lighting with the exception of comb plate lighting, step gap lighting, traffic light; b) cooling and heating, c) power sockets, d) alarm devices and emergency battery supplies equipment, etc.
