[Mark de la Fuente]

Friedemann,
 
I was going to suggest the perforate.cal file as well.

Subject: AW: [Radiance-general] perforated lamellas


Hi all,
I agree, but my simulation should give results for LEED minimal
requirements. There it is only one defined sky (midday, equinox, clear
sky) and a minimum average illuminance in the room behind the facade (+
turnable but not moveable lamellas) is required.
The lamellas I've to simulate are not the perforated mini blinds, but
get  a dimensions of 0.5 meter width and a length of about 3 meters.
The surface is brushes aluminum (adapted for redirect the daylight into
the room). 
With this starting position, I need a material definition which reflect
the daylight (direct and diffuse)  at  85% of lamella area and, on
account of the 15% of gaps in the lamellas, a light transmission of
15%.
Does anybody have an idea?

Thanks
Friedemann
