Re: [EnergyPlus_Support] Re: comis : windows vertices
My apologies for the extremely slow response to this. The overlap errors are
still a bit of a mystery. You can probably ignore them.
Regarding the ventilation flows, they will always be positive because there are
two different report variables which must both be reported:
Air Flow from FromZone to ToZone through COMIS Link
Air Flow from ToZone to FromZone through COMIS Link
