EN ISO 25745-1:2023 PDF

Overview

EN ISO 25745-1:2023 - Energy performance of lifts, escalators and moving walks - Part 1: Energy measurement and verification (ISO 25745-1:2023) defines standardized methods to measure and verify the actual energy use of individual lifts, escalators and moving walks during normal operation. Published by CEN and identical to ISO 25745-1:2023, this standard focuses on in-service energy measurement, periodic verification checks and reporting - enabling consistent, comparable energy performance data for equipment installed in buildings and public transport hubs.

Key topics and requirements

• Scope and focus
  • Measurement and verification of operational energy consumption for single-unit lifts, escalators and moving walks.
  • Explicit exclusions for lifts (e.g., hoistway lighting, HVAC in machine rooms, building management systems, effect of group dispatching, energy storage systems) and for escalators/moving walks (e.g., general lighting except comb plate/step gap lighting, HVAC, alarm/emergency battery equipment).
• Measurement procedures
  • Requirements for instrumentation, accuracy and test setup for lifts and for escalators/moving walks.
  • Distinction between main energy/power (drive consumption during running, idle and standby) and ancillary energy (auxiliary systems during running, idle and standby).
  • Specific procedures for lift energy measurements (main energy - running, idle/standby; ancillary energy) and escalator/moving walk power measurements (running, standby, autostart, slow speed, no-load).
• Verification checks
  • Methods for periodic on-site verification using current or power checks to confirm measured or expected energy performance.
• Reporting
  • Standardized reporting structure including general information, measured values for main and ancillary energy/power, and verification check results to ensure transparency and repeatability.
• Instrumentation coupling points
  • Guidance on where to couple meters and measurement devices for accurate capture of energy flows.

Applications and who uses it

• Building owners and facility managers seeking reliable, comparable data for energy management and decarbonization programs.
• Lift, escalator and moving-walk manufacturers and installers for product validation and warranty verification.
• Energy auditors, commissioning teams and testing laboratories performing on-site energy measurements and periodic verification.
• Asset managers and sustainability officers benchmarking equipment performance, prioritizing retrofits, or demonstrating compliance with energy regulations.
