Re: [EnergyPlus_Support] COMIS + nodes

["Michael J. Witte" <mjwitte@xxxxxxxx>]

The nodes used in the HVAC system inputs are not the same nodes used in the 
COMIS simulation.  "Air Flow from FromZone to ToZone through COMIS Link" (and 
the reverse "Air Flow from ToZone to FromZone through COMIS Link") are what you 
want to report.  Note that large openings can have bidirectional flow (for 
example, air can flow out the top of a large open window and flow in the 
bottom) so you need to report both directions.
