thanks for your opinion. I suspected was hard...in that
case I probably need to find a simplified calculation
model that takes into account my geometry
easily...especially for shadowing calculations; I will
implement it in Java. Do you maybe now a good calc method
I could look at for this problem (envelope thermal
