Mechanical Ventilation in Dymola and co-simulations

I have modelled a mechanical ventilation system in Modelica. I want to perform co-simulation using EnergyPlus for the building. I will export EnergyPlus as FMU and run co-simulations using Dymola as the master controller. From my mechanical ventilation model, I want to send to FMU the supply and return air temperature from the mechanical ventilation to the zone. I am planning to use an ideal mechanical system in EnergyPlus and override the temperature values (supply and return). Is it the best approach? Or is it more accurate if I send to EnergyPlus the sensible and latent heat outputs from the mechanical system in the zone?

I suggest to set the sensible and latent heat inputs in EnergyPlus, or you could use the development version of Spawn of EnergyPlus which couples directly HVAC from Modelica to EnergyPlus. You can check it out from the master branch at https://github.com/lbl-srg/modelica-b... See for example Buildings.ThermalZones.EnergyPlus.Examples.SmallOffice.Guideline36Winter

Thank you. I will check the Spawn of EnergyPlus example as you suggested
