[TRNSYS-users] Shading masks

[David Bradley]

Adrien,
   The first column in the *.msk file is the 
angle formed between the horizontal and an 
imaginary line drawn between the center point of 
the shaded surface and the top of the 
obstruction. If you enter an angle of 0° that 
means that the obstruction has a height of 0 in 
that direction and that the surface would be 
unshaded from sunlight coming from that 
direction. If you enter a value of 90° that means 
that the obstruction has an infinite height in 
that direction and that the surface would always 
be shaded from sunlight coming from that 
direction. 0° = no shading, 90° = complete 
shading (for that surface angle direction)
Cheers,
  David
