Hello Jevin,
You should only define interzone surfaces once.
It is possible to define an interzone surface twice in EnergyPlus, once in each of the zones that the surface separates. Previously this was a requirement of EnergyPlus (prior to version 2.0), but now it is optional and the user also has the option of only defining the surface once (EnergyPlus defines the second surface automatically within the program). For each interzone surface, use only one (of possible two) interzone surface names in the AirflowNetwork:Multizone:Surface object for “Surface Name.” Do not enter two AirflowNetwork:Multizone:Surface objects corresponding to the two possible interzone names. This would cause the air flow through the surface to be counted twice
