The flow networks were created via a scan of surface USE attributes
with user inputs. The facade grills are 20% of the surface area and
the supply and return grills are 100% of surface area. Volume flow 
rates for the mixing box fans are equivalent to 5 air changes per hour 
(6ach in manager).

office_hvac_infil.3dafn is used with all the model variants. The
changes in control are implemented via the flow controls.
