Hi

I'm modelling TABS (Thermally Activated Building Systems) via ZoneHVAC:LowTemperatureRadiant:ConstantFlow in EnergyPlus (EP). Could anyone tell me how the hydronic tubes/pipes are embedded in the system? I can't seem to find this in the EP documentation. Does EP consider the entire floor (finishing, insulation, concrete slab,...) as a whole and does EP put its tubes in the middle? Or does EP put the tubes in the concrete slab? Or something else? Thanks in advance!
