Re: [TRNSYS-users] TYPE68 + TYPE 34

[David Bradley <bradley@tess-inc.com>]

Christophe,
  It is a bit of a mess to combine Type68 and Type34 to do both overhang 
and far-away object shading on the same facade. What you need to do is to 
define a horizontal facade and your vertical opening in Type68 so that you 
can get the total radiation shaded by far-away objects on the horizontal as 
well as the beam radiation on the surface, which is what Type34 is 
expecting. We have a high priority item on our list of requested 
enhancements for Type68 to also calculate the shaded horizontal radiation 
for each one of the openings in the data file. I am not sure when that 
enhancement will be ready though. We will make an announcement to the list 
when it is ready.
Kind regards,
  David
