90.1 Window to Wall Ratio Calculation - Parking Garage

The Std 90.1-2013 definition of space excludes enclosed parking garages. I have a building with two floors of office space above two floors of enclosed parking garage, all above grade.

My question is: For the requirements of Section 5 for maximum allowable fenestration area (40%), the opaque wall area for the parking garage will be part of the total gross wall area?

Any references will be appreciated
