Hi Antoine, I couldn’t reproduce your problem. I used the tm2 weather file for cape town and I have got radiation on the north façade while there was no radiation on south. Yes, that is right, external shading geometry doesn't impact solar incident radiation on external walls, only on external windows.

Im Auftrag von Antoine Gautier via TRNSYS-users Hi There seems to be a problem with solar radiation computation in southern hemisphere when using the 3D import wizard: see attachment. South facade (azimuth = 180°) actually receives radiation whereas north facade (azimuth = 0°) does not. Also external shading geometry doesn't seem to impact solar incident radiation on external walls, only on external windows. Is that correct?
