Dear all,
I have 2 horizontal windows, shaded by the same
object, but from different angles, so I use two Type68 shading masks (one with
6 and one with 7 azimuth angles). I don’t trust the results however
because when I set one of the obstructions to zeros (all betas = 0), the beam
radiation is ok (equal to solar radiation) but the diffuse radiation is less
than the diffuse radiation output from type16. As trnsys does not now the
relative position of the windows (as far as I can see), I do not see why this
would happen. Has anyone any suggestions? Below are the obstruction files I use
(for debugging I set one to all-zeros and the other to all 100, these are not
the actual values of the obstructions)
