Jeff and Brian have pretty much covered it. I commonly end up with models including most of not all of the inputs described.<br>
<br>

<div style="direction:ltr; margin:0; padding:0; font-family:sans-serif; font-size:11pt; color:black" dir="auto">
I might only add that, for indoor heated pools in northerly climates, I have experienced some interesting and unique situations concerning ventilation and dehumidification of such spaces. In one case, I was charged with modeling an existing scenario where
"cloud formation" was a regular occurrence we were charged with fixing. Juxxz Resolving this issue required a combination of replacing active (but ineffective) dehumidification units within the pool space, opening up some (then blocked-off) grills between
the pool and adjoining locker rooms (locker exhaust was a critical component to achieve a more effective ACH rate) which incidentally helped to resolve some related odor/ventilation issues in the locker spaces, and adjusting the reheat capacity of the associated
AHU with a new coil.<br>

This is all primarily to suggest: I would advise deliberation before excluding from your model any adjoining spaces/systems which may play an impactful role on the operations of your pool conditioning systems. You might later wish you had those spaces/zones
incorporated from the get-go.<br>

Oh and if ever you were in search of a good application for solar HW heating as an ECM... Active indoor pools at northerly latitudes are a solid starting point. Just be extra<span id="ms-outlook-android-cursor"></span> mindful of snow cover in application/design
;-).<br>

<p>Hello Matt:</p>
<p><br>
</p>
<p>Here's a rather dated paper on how a proxy model was created for the Rec Center at the University of Colorado in 1985. The simulation was with DOE-2 and was actually calibrated to the indoor conditions at the pool, as well as the monthly energy use. The
1987 paper has additional information about how the measurements were used to create an expert system for diagnosing operation and maintenance issues.</p>
<p><br>
</p>
<p>Obviously, the DOE-2 program was not created to do this sort of thing, but it can be tricked into giving answers that mimic the measured performance.</p>
<p><br>
</p>
<p>Jeff</p>
<p><br>
</p>
<p>PS: The building also had a skating rink above the women's locker room that was also modeled (or mimicked) with DOE-2</p>

<div>
<div>Hello,<br>
</div>
<div><br>
</div>
<div>I am looking for general guidelines on how to model an indoor pool in eQuest, including energy requirements to heat the pool water, and energy requirements to heat/cool/dehumidify the air. If anyone has any resources to point me towards, that would be
greatly appreciated. The pool in question is located in northern Alberta, where the temperature dips to as low as -22 °F in winter. The pool has two small windows. Its roof is part of the building envelope, but its walls are not - the walls are adiabatic.<br>
</div>
<div><br>
</div>
<div>Thanks,<br>
</div>
<div>Matthew<br>
