1 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.
