Re: [EnergyPlus_Support] Daylighting also influenced by changing Set point Tempratures!

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

Because EnergyPlus uses an iterative solution algorithm with a finite 
convergence tolerance, changes in seemingly unrelated inputs could change the 
number of iterations.  I would assume that this is what is causing the slight 
change in daylighting results.
