[TRNSYS-users] Shading Mask

[David Bradley]

Julie,
  Your understanding is correct. If the mountains surrounding the valley 
are approximately the same height all around you can use Type64 which 
offers a slight simplification in that the same mask is considered by 
all of the openings (or facades) of the building.
Best,
  David
