Hello,

I'm trying to make a DF calculation with ecotect. I made a simple test : I modelise a room entirely closed, then I put a partition inside with a window. I run a simulation to get the daylight factor.
I don't understand why my DF is not null ?
However there is no external view and all my room is "in the dark". I have the same problem when I put a void instead of a window. The only way to obtain a DF=0 is to create my partition in several parts in order to make a hole at the right size instead creating a window.

Does someone can help me ?

Thanks a lot

Nicolas
