[Bldg-sim] LEED Swimming Pool Sizing and ACH

Demba,

 

In previous versions of LEED, I think you could consider the pool a process
load and model the natatorium as an empty space.  Now that you need to
include process loads, perhaps you can have the reference and proposed equal
unless you are trying to claim savings as Jim mentioned.

Dear Demba,

Airflow is only one of the comparisons for a pool.  The others, all very
powerful in impact, are de-humidification, and heat recovery from the
refrigeration system for reheating and pool water heating, and heat recovery
for outdoor air preheating.

ASHRAE Applications recommends a minimum of 4 ACH for natatoriums. Applying
that minimum to my Proposed leads to a somewhat oversized pool unit compared
to the Baseline system, which reduces my savings a lot. I couldn't find a
code requirement of a minimum amount of ACH, which would allow me to size
the Baseline with the same number of 4 ACH. Is somewhere aware of any such
code requirement?

 

A related question: would LEED allow to size the Baseline at 4 ACH, even
though the project is not a school?

 

Thanks for chime in,
