<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>As Bill alluded, you will also want to explore using another
software package to model how your open-loop system’s ground water
temperature will vary over the year, and use those results to create a
monthly/weekly (daily, if you’re really motivated!) temperature schedule
for eQuest to use on the LAKE/WELL exchanger. Going into this, you will
need to have ready your monthly loads incident on the loop, and any other
parameters you have regarding the GLHX design (area available on the site,
ground properties, etc…). There are free options like GS2000, though I’m
not sure whether that specific tool can really handle the behavior of an open loop
system – you might need to invest in a more sophisticated (and thereby “for-cost”)
solution… <o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>If anyone’s aware of a free or commercially available software
package that can model such open systems (which I suppose would necessitate
specifying the direction and rate of annual groundwater flow – for which
I’m not sure where you’d have to look for that historical data) I’d
personally be very interested to learn about it! The only option I’m
aware of for explicitly modeling this behavior for your energy model is to hire
out a specialist with proprietary software (who will go on to design the loop
system and assume liability for the design) – here’s the only name
I’ve picked up with this service: <o:p></o:p></span></p>
