<p class=MsoNormal>Dear Bldg-Sim community,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m trying to plan a LEED energy model which has a <u>swimming
pool</u> and am stuck thinking about how to model the baseline condition.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>A pool has such specialized needs that I have doubts whether
one of the specified baseline systems in ASHRAE 90.1 can do an acceptable job
of controlling temperature and humidity.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>At present, I am reasonably confident that I can schedule
the pool occupancy properly, add moisture in amounts that parallel the
pool evaporation and specify the pool heater energy. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My facility requires a “System 6” parallel fan
powered VAV box HVAC system (95,000 sq.ft., single story, multi-purpose
facility). This is not a system type that makes sense for a pool, so I
hesitate to use it at all. If I have to, for purposes of following 90.1,
I think it might meet temperature loads, but it certainly won’t meet
humidity loads, at least not at the specified 20F airside delta T. That,
of course means that overall energy use will not even be close to what will
actually be needed and the baseline will compare poorly with the actual (very
efficient) HVAC system.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ll appreciate any guidance from those among you who
have done LEED projects with pools!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance.<o:p></o:p></p>
