Re: [EnergyPlus_Support] Outward Facing Angle for a subsurface
If you look at the first 3 points in the BuildingSurface:Detailed
object, they are described opposite in direction to the fenestration
coordinates which may be confusing E+. I'm not sure of this, but you
could also try using point 3 as the first point in the list where point
1 and 2 would be listed last. You could also try splitting up the
surface into 2 or more surfaces where the fenestration surface is
"within" the boundary of a 4-point surface.
