[BLDG-SIM] Energy use for elevators

[Zhen Tian]

Eric,
   
  Thanks a lot for your reply.
   
  I have a further question. If we have the elevator power data, what appropriate schedule should we use to approximately to get the elevator annual energy use?
   
  I checked the ASHREAE Appendix G but cannot find appropriate schedule for elevators.
  I think the schedule of elevators are quite diffent from other schedules like occupancy scheule. One example, supposing people work from 8am to 6pm continuously, I guess that elevator working schedule should not be the same. Do you have any ideas what appropriate schedule should we use?
   
  Thanks a lot.
   
  Regards,
   
  David

  Yes, ASHRAE 90.1 Appendix G requires modeling elevator energy as long as it is designed in the project. You can come up a realistic schedule or stick to a standard schedule in Appendix G if necessary.

Dear All,

I have seen some messages these days asking the energy use of elevators. But it seems that there is no very accurate way of modeling annual lift energy use.

If we need to simulate building energy use according to ASHRAE 90.1-2004 for LEED accrediation in e-QUEST, do we need to simulate elevator energy use or not? Is it a must do? Could somebody with experience with this topic give me some hints?

Thanks a lot in advance.

Regards,

David
