FAQ F-00275
Is there an alternative to demonstrating idle and standby energy performance requirement from Vertical Transportation?

Projects may demonstrate compliance with the 'lift idle and standby energy' requirement from the Vertical Transportation criteria by demonstrating that the following energy saving features have been incorporated in the lift specification:

  • Energy efficient Gearless AC Machines with regenerative VVVF drives;
  • Low energy LED lighting;
  • Shutdown of non-essential lighting, screens, etc. when on standby; and
  • The lift idle and standby energy performance level is at least level 3 in accordance with ISO 25745-2

This guidance is based on industry feedback that most lifts cannot currently achieve performance level 1 in accordance with ISO 25746-2 for lift idle and standby energy.

Documentation Requirements:

Please provide the following in your submission:

  • Schedule identifying all vertical transportation systems installed in the building, and the manufacturer and model of each.
  • Extract(s) from the commissioning report demonstrating (through supporting evidence) that the vertical transportation systems have been commissioned and operate as intended by the design.
  • Documentation showing the lift idle and standby energy performance level is at least level 3 in accordance with ISO 25745-2
  • A copy of this response.
