Output variable for sunspot surface in an interior surface
Hi,
I'm looking for an output variable of ENERGYPLUS which give us the sunspot (or sun patch) surface of an interior surface in a building.
Thanks for advance,
I don't believe the variable you are looking for exists. The closest thing you may be able to get is the solar radiation time-series on the surface from which you may be able to derive the fraction of the surface that is in the sun but not the geometry of that fraction. Look here for surface output variables.
