Re: Direct solar radiation Type 56

[sim@xxxxxxxxxxxxxxxxxxxxxx]

Thank you Michaël,
but does Geosurf also work if I have 5 zones after each other, not only two like a 
double fassade? Is it possible to let direct solar radiation from outside pass trough first, 
second, third and fourth zone and being absorbed on a surface in the fifth zone?
