Regarding the minimum ventilation rates in Table 1, the 2015 ASHRAE Handbook--HVAC Applications section on
natatoriums states:
In the arid West, summer introduction of outdoor air does not present the cooling energy penalty to a
Natatorium Air Conditioning System as it would in the more humid ambient conditions of the South and Southeast sections of the US.
In response, the government is planning to invest $625 million annually to construct more than 3,000
natatoriums, according to CSA.
I read April's "Designing for IAQ in
Natatoriums" by Randy Baxter with interest.
If your business isn't located in an area that supports a large commercial market--municipal pools, health clubs,
natatoriums, condo complexes and the like--you'd be better off focusing on residential pools.
Pools and
natatoriums have incorporated stainless steel components for more than 40 years.
I would like to make some comments regarding April's "Designing for IAQ in
Natatoriums" by Randy C.
Partner with swim clubs, schools and
natatoriums to spread the truth about chlorine.
Only within the last several years have researchers identified indoor
natatoriums as sources of endemic lung disease (Rose et al.
Source capture and exhaust of trichloramine vapor (and all other heavier-than-air DPBs) reduces the potential for corrosion, potentially reducing the need for expensive corrosion-resistant materials and coatings in
natatoriums and equipment.

Natatoriums.
Admittedly, not many of these buildings have
natatoriums, but most were built before energy codes or Standard 90.1 were required.
