Hi,
Method 1 - create a component that models the grill - made up of thin (planar if very thin) horizontal and vertical strips, with the required perforation.
Method 2 - treat the sheet as something which modifies the glazing - so if it shades by 70%, then reduce the transmissivity of the glass by 70%. This is particularly effective for use with the CIE Overcast Sky as used for the DF calculation.
Hope that gives you a start.
