[TRNSYS-users] overhang

[David BRADLEY]

Leen,
   If you are using Trnsys17 and Trnsys3D, this is fairly 
straightforward. You would add a shading device to the Trnsys3D model 
and Type56 would automatically assess its impact provided that you ask 
TRNBuild to generate the shading mask. If you are using Trnsys16 or want 
to rely on Type34, what I would suggest is that you define approximately 
three Type34s. Define each one's aperture to be the height of the facade 
and about 1/3 its length. For simplicity, pretend that the total facade 
is 100m long and that the overhang projects 1m. One Type34 will have a 
66.6m left overhang extension and a 0m right overhang extension. The 
second Type34 will have a 33.3m left overhang extension and a 33.3m 
right overhang extension. The last one will have a 0m left extension and 
a 66.6m right extension. All three will have a 1m projection. I would 
then take the solar radiation computed by those Type34s and pass it to 
the Type56 facades. Bear in mind that you will have to break the Type56 
facade up into three parts and you will have to assign each part its own 
"orientation" not because they face different directions but because 
Type56 associates orientations with a unique amount of solar radiation 
falling on a surface.

   Of course if you don't think that three pieces is enough precision, 
you can break the facade up into more pieces.
Best,
  david
