Re: [EnergyPlus_Support] combined effect of shading devices on interior temperatures



Neslihan:

I looked at the input file and found two issues using the AirflowNetwork 
model.

1    Parent surface facing

Any parent surface defined as an AIRFLOWNETWORK:MULTIZONE:SURFACE does not 
allow the parent surface faces itself: the user supplied surface name = 
OutsideFaceEnviroment object. The reason to reject this choice is that the 
prarent surface has to face different interior and exterior boundary 
conditions, so that the AirflowNetwork model can work. A severe error 
message in the eplusout.err shows it.

2    Wind direction

Wind direction fields used in the AIRFLOWNETWORK:MULTIZONE:WIND PRESSURE 
COEFFICIENT ARRAY object do not allow the repeated values. The object is 
enclosed.

As long as you make the above two issues correct, the AirflowNetwork model 
should work. However, you still have other warning issues.

Best regards,

Lixing
