Re: [EnergyPlus_Support] Convection from waffled ceiling soffits

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

If this mass is completely enclosed within a given zone, or separating two 
zones at similar temperatures, then describe it as internal mass and vary the 
area vs. thickness (Surface:HeatTransfer:InternalMass).  If this is an exterior 
surface or separating zones at different temperatures, then the best I can 
suggest is to modify the convection coefficients on the waffled side 
(ConvectionCoefficients).
