[Equest-users] Data Center modeling

[Bruce Easterbrook]

By default equest will assign a ahu system to each floor.  Save a copy 
of the files, PD2, INP, and open the copied project.  On the action tab 
to the left click building creation wizard, ignore the warnings and go 
back, you have a disposable copy right?  Get to the project navigator 
tab.  If you have everything done right you will have your zones under 
the building shell components and under the air side system types you 
from the sound of it you will have HVAC system 1.  You can create your 
new systems using the tab below.  Create what ever systems you need.  
Press finish.  Get into your waterside HVAC tab, it is better explained 
as your system tab.  Look down on the left in your component tree and 
you will see air-side systems.  All you ahu's should be there.  Just cut 
and paste your zones out of HVAC system 1 into the air handlers you want 
them in.  If you empty HVAC 1 of zones delete it.  Ideally you should 
now have all your zones where you want them.  If not save again, go back 
into the building creation wizard and try again.  Good luck.
