Hello,

I?m currently working on a model for a LEED project. The parking garage is
heated only with unit heaters and no cooling. The garage is also
ventilated naturally with aluminum grilles. What is the correct way to
model this for a LEED project? Also, how do I take the grilles into
account? I currently have them in as windows, but I am not sure what do
since they are essentially openings in the envelope.

Thank you
