Hello All,

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.

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.

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.

Thanks in advance.
