<p>Manfred,</p>
<p> I believe that the requirement for convex zones only applies to
using the detailed radiation mode to deal with the interior
radiation exchange. In other words I think it applies only to the
*.vfm file and not to the *.shm file since the *.shm file deals
with shading on the outside of the building. Please someone
correct me if I am wrong about that.</p>
<p>kind regards,</p>
<p> David</p>

a few shading objects. In the existing model I just used
shading factors from PHPP, only differencing between summer
and winter. Now I want to have more detailed shading factors
and want to use the shading matrix (shm) but as I read in
the documentations I need convex zones for it. Or is it
working with concave zones, if I just use the detailed
radiation model for the beam radiation distribution (and for
the diffuse radiation distribution and the longwave
radiation exchange within a zone the standard models)? As
far as I can see the geometry of a zone is indifferent for
the shm-File – isn’t it?<o:p></o:p></span></p>

was to build up the same 3D-Modell but with only fictitious
concave zones, so I could get the shading factors in the
shm-file. Is there any type I can use to read the shm-matrix
into my simulation with the concave zones?<o:p></o:p></span></p>
