<p class=MsoNormal>All:<o:p></o:p></p>
<p class=MsoNormal>I have dedicated individual FCU's at several zones. Each
FCU is to be connected to a CHW and HW loop which comes from a campus central
plant. The intention was to have the FCU directly feed the conditioned
air to the zone w/ no terminal unit; only a thermostat and meter would be
included as the "zone features" components.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Question: Why does eQUEST not allow me to specify "Chilled
Water" as the "Cooling Source" for the FCU's? Instead it
forces a zone terminal to be connected to a CHW and HW loop (which I do not
want). Any thoughts?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Also, when comparing my baseline (FCU system as described
above) model to the design case (AHU connected to VAV's w/ reheat) the CHW load
is larger for the FCU system (2727 hours compared to 1750 for design-case) but
the CHW energy use is lower in the baseline scenario (72Mmbtu vs. 120).
This seems counter intuitive. What might cause this?<o:p></o:p></p>

<p class=MsoNormal>Your time and feedback are always appreciated.<o:p></o:p></p>
