Depends on what you want to find in your simulations. The shaded regions 
may be of interest if you are looking into glare, and may switch a 
sensor. For an overall annual assumption of daylighting potential you 
may be fine with the uniform transmission approach. Mark Stock has some 
nice cal-file to create a facade with uniformly distributed openings, 
but in general mixfunc is perfect to describe such systems. Of course 
unless the facade / mullions are not flat but have a thickness to 
consider (again for e.g. glare).

Cheers, Lars.
