Wrong. But hey, when we were coaches and lifeguards, we opened doors too; we didn’t know any better. This message today is for anyone who opens doors to their indoor pool, especially in the winter time. Please stop doing it…opening doors is making the air quality worse.
It sounds odd to say that, doesn’t it? The truth is, the little bit of outside air you’re introducing into the natatorium is usually causing more harm than good, for several reasons. When it’s cold outside, the air you’re bringing in through the doors is unconditioned, and therefore adds a tremendous amount of stress on the building’s HVAC system. As swimmers and coaches, however, you probably think like we do—health is far more important than the efficiency of an HVAC system. We believe everyone deserves to breathe healthy air, and that the aquatics and HVAC industry experts have a moral imperative to deliver it to all pool users. The problem is, opening doors does far more than just stress the HVAC system…it creates more airborne pollution.
If you have read our articles on SwimSwam, you know that chloramine related air quality issues are inevitable, and caused by basic chemistry and air physics. Opening doors complicates the air physics, by encouraging faster evaporation of the pool water. Cold air lowers the vapor pressure pushing down against the pool water, which allows for a faster rate of pool evaporation. With more evaporation comes more chloramines, and thus begins a vicious cycle of bad air quality.
In summary, we know that opening doors makes those near it feel better, and provides some short term relief for swimmers and coaches on deck. But in reality, it’s doing more harm than good by not only stressing the HVAC system, but also increasing the rate of chloramine pollution in the air. There is a better way to handle these issues, and we encourage you to research the affects of bad air quality for yourself.
As you are probably aware of the damaging and harmful affects of poor IAQ in natatoriums. Difficulty breathing, watery eyes, even coughing are probably common signs to you. You might notice it from an operational aspect. Rust and corrosion, equipment breaking down more frequently than it should, constant cleaning and upkeep… All are signs of IAQ issues. The following article, printed in Private Universities Products and News magazine, explains some traditional natatorium design philosophies and how they can contribute to IAQ issues.
Swimming has always been considered a “healthy” sport – it has low impact on our joints and bones, makes us use muscles we typically would not use, and is a great cardio workout, burning many calories. Swimming also continues to grow in popularity and participation levels are at an all-time high. All of which are great things we love to see happening. But in the last year, the swim community has managed to make swimming even healthier. Click the link below to read 4 ways that swimming became an even healthier sport in 2014.
The Paddock Evacuator System creates a pristine breathing environment, helping athletes train harder and longer in indoor pools.

The Paddock Evacuator helps GAC secure the YMCA Short Course National Championships for 3 more years.
Bob McCallister, Aquatics Manager for Cobb County, Georgia, shares his testimonial of how he finally conquered bad air quality in his four indoor pools.
An exciting article about the recent success at GAC to fix their air quality issues during the 2014 YMCA Nationals.
Carbondale YMCA recently installed a Paddock Evacuator Bench System – hear from Steve Durkin, CEO of the Y.
JTAC, a world-class facility, maintains great air quality with the installation of two Seresco Dehumidifiers and the Paddock Evacuator.
GAC HVAC renovation includes the addition of two Evacuator Systems.
Greensboro Aquatic Center (GAC) announces the addition of the Paddock Evacuator System in the near future!
A recent swim event hosted at Westside Aquatic Center in Greenville, South Carolina brought in over 600 swimmers from 12 different states around the country. It is said to be the first major national event held at the facility, hosted by Team Greenville (www.tgswim.com). The initial planning of this facility actually challenged Paddock Pool Equipment Company, who manufactures the Paddock Evacuator Gutter System, to create the initial concept of the Evacuator.

A must read publication outlining indoor air quality in indoor aquatic facilities.
An email sent from USA Swimming’s Coaching Connection says it all – including a bold statement that should be posted in every pool, both indoors and outdoors.
Anyone who has been around indoor swimming pools knows how awful the air in the room can become if it is not handled correctly.
As swimmers, lifeguards, or pool operators, you begin to dread having to visit facilities that seem to have “out of control” air quality issues. Our noses revolt, our eyes water, and our lungs begin to burn. Many of us have cold or allergy symptoms for days after even the briefest of visits to such facilities.
An case study focusing on Jenks Trojan Aquatic Center’s pristine air quality after the installation of a Paddock Evacuator System.
To address a growing concern, the staff of Y-USA’s Property Development Department has been researching new technology to eliminate chloramines from the pool environment before they reach the bather and spectator respiratory systems.
New technologies, such as ultra-violet light, have been effective in controlling chloramine. Well, there is another new technology that appears to be more than promising. This is the Paddock Evacuator. Several YMCAs across the country have installed the Evacuator either in their built in to the gutter system as a retrofit or on the pool deck which looks similar to a bench.
Randy C. Baxter, the author of the original article ‘Designing for IAQ in Natatoriums,’ which was published in the April 2012 edition of the ASHRAE Journal, responds to the comments of various readers regarding his article.
The purpose of this article is to review the literature concerning the effects of disinfectant by-products on indoor swimming pool air quality and to propose practical methods for mitigating their impact in conventional (recreational and competition) indoor pools.
