Subject: [BLDG-SIM] Energy use for elevators<br>
<br>
Dear All,<br>
<br>
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.<br>
<br>
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?<br>
<br>
Thanks a lot in advance.<br>
<br>
Regards,<br>
<br>
David<br>
