<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If there is an adjacent or nearby air conditioned space, a heat pump water heater could be considered using the pool as a heat sink. Or a small power generation
system and use the waste heat for pool heating.<o:p></o:p></span></p>

looked at.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If part of maintaining the pool water chemistry includes the use of sodium bicarbonate, going to a CO2 injection system can be low hanging fruit with a payback
in chemical usage of about 2 years or less. Chlorine pumps are generally a maintenance headache. Using a venturi type chlorine injection system can provide good maintenance savings.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Pool filters are generally of the sand filter type or diatomaceous earth type. Sand filters have high backwash requirements with a considerable amount of water,
heat, and chemical being dumped to drain. Diatomaceous earth filters have high pressure drops, requiring more pumping power. In both cases, pool pumps need to be sized for worst case conditions of the filters being plugged. Perlite media filters are pretty
much self-cleaning with low backwash requirements and low pressure drop, allowing the use of a VFD to vary flow rate between occupied and unoccupied periods.<o:p></o:p></span></p>

<p>Dear Aaron, <o:p></o:p></p>
<p>For the schedule, it really depends on the project you are working at I think.<br>
The gym I frequent uses fans in addition to the cooling, that can be a energy efficiency strategy.<br>
Good luck,<br>
