Re: [EnergyPlus_Support] About Absorptance Thermal coefficient of material

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

Typically, the impact will be small, but there are cases where the impact can 
be significant.  Thermal absorptance is not used when the convection model is 
set to SIMPLE.  Perhaps that is why you did not see an impact.
