Annotation of standard text ČSN EN ISO 25745-2 (274006):

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 unlikel
