scope:

This part of ISO 25745 specifies the following: a) a method to estimate energy consumption based on measured values, calculation, or simulation, on an annual basis for traction, hydraulic, and positive drive lifts on a single unit basis;

b) energy classification system for new, existing, and modernized traction, hydraulic, and positive drive lifts on a single unit basis;

This part of ISO 25745 applies to passenger and goods passenger lifts with rated speeds greater than 0,15 m/s and only considers the energy performance during the operational portion of the life cycle of the lifts.

NOTE 1 For other types of lifts (e.g. service lifts, lifting platforms, etc.), this part of ISO 25745 can be taken as a reference.

This part of ISO 25745 does not cover energy aspects, which affect the measurements, calculations, and simulations, such as the following:

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 display systems, CCTV security cameras, etc.;

f) non-lift monitoring systems (e.g. building management systems, etc.);

g) effect of lift group dispatching on energy consumption;

h) environmental conditions;

i) consumption through the power sockets;

j) lifts whose travel includes an express zone.

NOTE 2 An express zone is unlikely to affect the average car load but can significantly affect the average travel distance.
