[Bldg-sim] LEED baseline and swimming pools

[James V Dirkes II, PE]

Dear Bldg-Sim community,

 

I'm trying to plan a LEED energy model which has a swimming pool and am
stuck thinking about how to model the baseline condition.

 

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.

 

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.  

 

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.

 

I'll appreciate any guidance from those among you who have done LEED
projects with pools!

 

Thanks in advance.

THINGS YOU WOULD NEVER KNOW WITHOUT THE MOVIES

 

All telephone numbers in America begin with the digits 555.

 

The ventilation system of any building is the perfect hiding place.  

No one will ever think of looking for you in there and you can travel 

to any other part of the building you want without difficulty.
