Hello everyone, when modelling unitary heat/cool system do we need to have sizing plant? Since I don't know inputs for the plant, I've autosize just the zone and system to achieve thermostat setpoint and it worked. But for ideal load air system just sizing zone is enough to maintain thermostat without having to use sizing system and plant. My objective is to compare between the two system and I am not confident whether the models are correct or not for co-simulation with Contam and EnergyPlus. Thanks in advance for the advice https://drive.google.com/drive/folders/1DvtvjGtFOMiaKulCSxTiHy4BcglUUyos?usp=sharing
