Re: [EnergyPlus_Support] a problem about daylightshelf

Sunlit area too small errors can sometimes result from using the wrong corner 
as the first vertex.  The first vertex must be consistent with the 
SurfaceStartingPosition field specified in the SurfaceGeometry object (for 
example, UpperLeftCorner).
