Passive Chilled Beams and Active Chilled Beams

Hi everyone, I’m trying to model two systems, a Passive Chilled Beam and an Active Chilled Beam in Ironbug, however both systems are giving the same results in terms of energy consumption. I am starting from the ‘Sys12_Active Chilled Beams + DOAS’ template in Ironbug and changing the ‘Cooled Beam Type’ from ‘Active’ to ‘Passive’ and the coefficient of induction from 2 to 0 (default values). Are there any other other parameters or changes I should do to differentiate between these two systems?

Thanks!
