[BLDG-SIM] DOE-2 Hourly Information sought

["Aulbach, John" <JAulbach@xxxxxxxxxxxxxxxxxxx>]

I am trying to ascertain the effect that outside air has on the energy load of a school. There are 27 air units I am running as SZRH (and they really DO have reheat coils versus a heating coil).

 

By the way, I input the outside air requirements at the ZONE level (actually one ZONE corresponds to one SYSTEM).

 

In my perusal of hourly parameters, there really is no specific component for outside air ANYTHING shown. I have attempted to use the Return Air Temp and the Mixed Air Temp, along with the fixed Total Supply, Return, and Outside air volumes to do a mass balance, thus determining the OSA cooling and heating energy components.

 

But the hourly data shows the Return and Mixed Temperatures almost identical. Because I put the Outside Air in the ZONE command, is it acting like Infiltration? Should I be bringing it into the SYSTEM level instead?
