Mechanical Ventilation in Dymola and co-simulations

edit

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?
