[TRNSYS-users] Mask Shading on ceiling of buildings (type 68)

[David BRADLEY via TRNSYS-users]

Arian,

   The obstruction height angles are measured from the horizontal to the 
top of the obstruction. The plane in question (from which the height 
angles are measured) for the roof/ceiling is the horizontal plane. In 
fact, the plane in question is always horizontal, regardless of the 
slope of the facade in which the opening is located.

kind regards,

  David
