[BLDG-SIM] Equest - Floor Multiplier and Outside Air Handling Unit Problem

[Jonathan Curtin]

I am having a problem modeling a dedicated outside air handling unit in
Equest. I have followed past advice from this mailing list and also the
DOE2.2 manuals, but the OAHU is not sized correctly in my simulation
runs.
 
I have specified a constant OAcfm/sqft in each zone to simulate a
constant volume unit, and the air handling units served by the OAHU link
to it with the OA-From command. But there appears to be a problem in
that the OAHU will fail to recognize the zone OA requirements from zones
defined by floor multipliers, and therefore it is not sized properly.
For example, my 10 story building (Ground, Mid (x8), Top) will have the
OAHU sized for 3 floors only (Ground, Mid, Top).
 
Has anyone out there experienced this same problem, or know of any way
to resolve it?
 
Thanks in advance,
