<DIV><SPAN class=025015218-07012009><FONT face=Univers size=2>I'm having a lot
of difficulty simulating a very common VAV w/reheat system. My total
energy intensity is way too high for this building type and the problem I think
is due to a lot of reheat that's going on. </FONT></SPAN></DIV>

<DIV><SPAN class=025015218-07012009><FONT face=Univers size=2>I've tried a few
things but they have not helped. Fop example, if I specify a heating
availability schedule that is the same as my set-point heating schedule my
energy use goes down, but I end up having close to 20% unmet heating
hours. If I leave it unchanged, the unmet heating hours go away but my
heating profile looks terrible, with a lot of reheat in the summer.
Whether I create reheat coils in the zone, or baseboards, it seems to have very
little effect. I think there's a fundamental problem with how the zones
are controlled but I don't have enough experience to trouble-shoot the
problem.</FONT></SPAN></DIV>

<DIV><SPAN class=025015218-07012009><FONT face=Univers size=2>I've attached the
pd2 and inp files for anyone willing to give it a try. I'm very frustrated
at this point, because this is probably the most basic system I can think of and
very common here. I have never been able to get these VAV w/reheat systems
to work well, as there is always either unmet hours or a lot of
reheat.</FONT></SPAN></DIV>
