Re: [EnergyPlus_Support] Determining sunshine exposure with EnergyPlus

["Michael J. Witte" <mjwitte@xxxxxxxx>]

Daylighting does not report beam and diffuse components at a reference point.

There are some surface report variables which will report this:

 Beam Sol Intensity from Ext Windows on Inside of Surface[W/m2]
 Beam Sol Amount from Ext Windows on Inside of Surface[W]
 Beam Sol Amount from Ext Windows on Inside of Surface Energy[J]

For these values to be meaningful for determining the direct solar at a 
specific place in the zone, you would need to describe a small surface or 
subsurface in the exact location of interest and use the 
"FullInteriorAndExterior" or "FullInteriorAndExteriorWithReflections" solar 
distribution option in the BUILDING object.
