<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>“Multi-zone” is a type of AHU.
It does not mean that there are multiple AHUs serving the same space. A multizone
air handler separates the air in the unit and blows some air across a cooling
coil and the rest of the air blows across a heating coil. Dampers at the end of
the AHU then mix some of the hot air with some of the cold air to get the mixed
air temperature needed to meet the load in the space for each of the zones. If
the air handlers are like this, then your air system selection is correct. I
would not expect a multi-zone air handler to be used in a big open space. They
are used where there are different thermal zones that need to be served by the
same system. I suspect that the air handlers in your building are constant
volume, single zone, instead of multi-zone. Hope this helps.<o:p></o:p></span></font></p>
