Re: [EnergyPlus_Support] how to simulate atrium and its adjacent offices

["nicole chen" <cloris.chen@xxxxxxxxx>]

Dear Michael

about that question we discuss before, there is another problem. That is how
to define the type of inter-zone walls and window. Are they belong to
exterior wall , and should they be set to sun exposed and wind exposed. If a
internal wall can be set to sun exposed and wind exposed? Thank you .
