Andrew,<br><br>Create a Dummy space, very small 1ft x 1ft x 1ft with no load and then a Dummy Zone for it and use this for your zone. I would not use Multi Zone but rather PSZ if you are supply the fresh air at a constant volume or PVAVS if it is supplied at a variable volume.<br>

Hi All,<br>
<br>
I am trying to model a building which has a minimum fresh air AHU serving all zones, each of which also has a local cooling unit. I was trying to model this using a single zone AHU for each zone, with outside air to all units coming from the multizone unit, which I created later, however I am getting an error saying that the multizone AHU needs to be assigned at least one zone. How can I do this, when all of the zones are assigned to a local unit? If I assign a small zone to get rid of the error, will the multizone AHU only be sized for the cooling load associated with this zone? How can I confirm that the multizone AHU is sized for the appropriate fresh air load?<br>
<br>
Regards,<br>
<br>
Andrew<br>
