It looks like its reheat for humidity control. If you set your humidistat to 
100% (no humidity control) you’ll see a more normal version.

Vikram & Eddie:

Thank you, I changed the OA From to undefined and that corrected my cooling 
energy during the cold months, but as Eddie mentioned, I have a lot of heating 
going on during the summer months.  Any idea why?

Sincerely,

Paul Diglio

Just to add to what Eddie said – you will spec OA from only when you are 
borrowing outside air from another system (Like with a DOAS). I’ve actually 
never seen this before (where you specify OA-From as the same system). What its 
probably doing is taking your return air as OA (at around 78) and cooling it 
(and taking moisture out of it). 

 
I would have thought it would give you an error.

In both of your HVAC systems you have "Outdoor Air From System" object 
specified.  In most cases, you will want to leave this object blank. The only 
time would want to use that object if, for example, you were taking the return 
air from one system, and using it in another, separate, system.  I am pretty 
sure that in your case, especially in the labs, all of the air will be coming 
from the outside, or will be recirculated within the same system.  
 
If you reset those values to their default you get much better cooling results, 
but you also get heating in the summer, which is another issue you need to look 
at in more detail.  The "Outdoor Air From System" object is found in your HVAC 
system --> Outdoor Air --> Outdoor Air and Economizer
