RE: [EnergyPlus_Support] hollow core slabs




Dear Athinodoros,

EnergyPlus cannot model non-homogeneous layers such as the hollow core slab.  That layer should be modeled with the correct mass (thickness + density) and an average conductance.

The embedded pipes are not something I have modeled, but I believe that there are several radiant floor objects that will work for you.  Look into object names such as ZoneHVAC:LowTemperatureRadiant:ConstantFlow.
