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
