[EnergyPlus_Support] Co-simulation with low temperature radiant component

["robertogrilloait@xxxxxxxxx [EnergyPlus_Support]" <EnergyPlus_Support@xxxxxxxxxxxxxxx>]

Hello all,

My goal is to do co-simulation between EnergyPlus and TRNSYS, using the latter to model a heating plant. 

With radiator heating, it goes fine:

Using ExternalInterface: FunctionalMockupUnitExport:From:Variable, I get zone temperatures as EnergyPlus outputs.

Using ExternalInterface:FunctionalMockupUnitExport:To:Schedule, I get TRNSYS-calculated heat powers into a schedule, which is then used by an OtherEquipment object.

Now I would like to model a low temperature radiant system, and I do not know how to do it. Ideally, I would obtain the flow rate and temperature of hot water in the system from TRNSYS, but how could I feed them back into EnergyPlus? 

Would you have idea of how to achieve this? Probably using EMS?

Thank you for your ideas!
