Hi Anurag, even though you may not be able to model your system exactly in DesignBuilder, there is almost always a way to model airside systems using DesignBuilder's available objects in a way that gives you an accurate estimation of energy use (without having to use the custom EMS or Python scripting). Without knowing your exact system, here are a few ideas that I thought of: - combine the DOAS and AHU into one unit in the model (using a standard AHU in an Air Loop). You - if your AHU serves a single zone, you could model your DOAS as the AHU in the Air Loop, and your AHU as a FCU in the zone
If those don't clear it up, are you able to provide a bit more detail on how your system is set up, maybe a little diagram or something? I may be able to give you a better suggestion.
