Re: AW: [EnergyPlus_Support] Internal surface
It is generally recommended that such surfaces be described without geometry
using Surface:HeatTransfer:InternalMass. The total surface area of the
internal mass surface should equal the total exposed surface area (top and
bottom). If you want to describe such a surface with full geometry, then you
would need to describe it twice, once facing up and once facing down.
