Marco,
Surely you can do this in E+, but you don't have to create two radiant systems in the ceiling.
Just create a cooled ceiling and add heating objects to it.
You can find examples in the Energyplus example map. RadLoTempHydrHeatCool.idf is one of them.

Dear all,
I'm trying to model a thermal zone with a low temperature radiant ceiling which can heat or cool the zone according to the zone need. The real system is composed by the same pipe circuit in which flows hot water in winter and cool water in summer.
I created 2 different HVAC circuits with 2 ZoneHVAC:LowTemperature:Radiant.
Managing the .idf and assigning the 2 ZoneHVAC:LowTemperature:Radiant (one corresponding to the heating circuit and the other the cooling one) to the same ceiling surface (whose construction is correctly related the internal generation) seem to be not allowed.
** Severe ** Surface 10_ROOF_1_0_0 is referenced by more than one radiant system--this is not allowed
At this point, I can't imagine how to model a ceiling with a heating and cooling function. Do you know if something similar is possible in E+?
I would upload also the starting idf in which the radiant and heating system is implemented in the floor surface. Changing the surface generating reference in the ZoneHVAC:LowTemperature:Radiant is not sufficient.
Thanks a lot,
Marco
