[BLDG-SIM] Energy use for elevators

David,
Table G-E to G-N in the User Manual for ASHRAE 90.1-2004 provides the default schedules (occupancy, lighting, HVAC, DHW and Elevator) which can be used for Appendix G analysis if the actual schedules are not known.
Moreover, if you are using eQuest then in the detail mode go to daily schedules and right click and select 'create daily schedules' and in the pop-up window click on 'Load Component from Library'. Form the drop down menu in the 'Category' select 'Elevator Schd' and from drop down menu in the 'Entry' select the appropriate schedule. And then go on to make weekly and annual schedules.
I have not made a comparison, but they might be a bit different from the schedules provided in the User Manual.
Furthermore, you can assign the elevator power data (in kW) directly to the Electric Meter using the 'Interior Direct Loads' tab and then selecting the elevator schedule from the drop down menu. This enduse can be assigned to Misc Equipment and will show up in addition to the plug loads in the BEPU and BEPS report.

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
