<p class=MsoNormal>Dear Bldg-Sim community,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’ve just completed a lovely, accurate, comprehensive
building energy model (in Energy Plus) which contains an indoor swimming pool.
The building is about 100,000 square feet and the pool area is about 10% of
that total.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>At the end of the year, the heating, cooling, fans and pumps
associated with the pool have consumed 70% of the total building energy!
I was rather surprised. I expected it to be a large percentage, but not
THAT large! This, by the way, is the result when using a specialty pool
HVAC unit which recovers and re-uses most of the DX cooling energy and thus
greatly reduces the pool energy total.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>As far as I can tell, ALL of the pool-related energy is
considered by ASHRAE 90.1 and LEED to be “process” energy.
Since “process” energy must be identical in both the baseline and
proposed models, the rest of the building must accomplish the entire savings …
which is pretty darn difficult (impossible, really) if “process” is
too large a percentage.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Have any of you successfully modeled a building with a pool
and also received LEED certification? If so, can you suggest what I might
be missing?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance.<o:p></o:p></p>
