How to model open exterior walls?

edit

Hello everyone.

I am writing a paper about the thermal comfort analysis of a free-stall for dairy cattle, and would like to use EnergyPlus/OpenStudio for modelling. But the construction has lots of opened spaces in the envelope, and even some exterior walls are void. How can I model this construction in OpenStudio? I have been considering the air wall construction, is it suitable for my case?

Thanks in advance!
