color=#0000ff size=2>Based on your description, I don't think your best option
is a whole-building energy model such as eQuest or EnergyPlus. I believe
your best option is an empirical model. I suggest you review the ASHRAE
1050-RP research, and see if the models presented there might be more applicable
to your task. They will also be much, much easier to learn and use.
You can either use the 1050-RP toolkit, or depending on your needs, you might
find it handier to create spreadsheet models. You can find some good
examples of the use of those approaches in the Texas A&M web
library.</FONT></SPAN></DIV>

/ Bldg Modeling<BR></FONT><BR></DIV>

<DIV class=Section1>
<P class=MsoNormal>I’ve been tasked with finding a software package that can
model our chilled water system. We have a district plant that
distributes chilled water to many buildings on our campus. My specific
task is to model the chilled water system of one specific building, then those
results will determine if we continue looking for a different software package,
or proceed to model the other buildings. Pretty much they want a computer
model of the buildings chilled water system that can predict the chilled water
flow requirements for each AHU & the total building as a function of the
buildings chilled water supply temperature, outside air conditions, and air
handling unit flow rates.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
<P class=MsoNormal>I’m looking at eQuest & EnergyPlus (as they’re the only
free options I’ve found so far to play with), and I’d really like some
opinions/suggestions on how to proceed.<o:p></o:p></P>
<P class=MsoNormal><o:p> </o:p></P>
