    AHU = Air handling unit
    MAU = Make-up Air Unit

    MAU should be 100% outside air for mabye a ventilation hood or something like that.

    Regards

          You will use your AHU because it is more economical to re-heat/cool air than to continually heating/cool outside air. But if you have an exhaust sytem pumping air outside you need to replace this air to prevent a negative pressure inside the building. The MUA unit will/ should be interconnected to your exhuast system.
