[Equest-users] PIU vs. VAV in eQuest

[Matthew Dubrovich]

For those that are on both the BLDG-SIM and this list, I apologize for
the repost...

 

 

Question on PIU vs. VAV systems in eQuest...

 

If a PIU system has only SVAV boxes and all other parameters are
identical, does the PIU act like a VAV in eQuest?  Only changing the
system type in my model seems to have a significant impact on energy
usage and I can't track down why that is.  The difference is significant
enough that with App. G System 7 VAV w/RH, the choice between PIU and
VAV has an effect on the number of points.  Any thoughts would be
appreciated.

 

 

Thanks,

 

Matt
