INTRODUCTION
The Basics
The natatorium experience for a patron should be no different than any other room in a building.
It should be comfortable, healthy and have good air quality. When designing a natatorium the first
recommended step for the designers is to meet with the facility owners to discuss the desired
operation and expectations for their natatorium. Only once the operating conditions and
expectations are defined, can the designer effectively calculate loads and address all
the key design aspects.
There are many critical considerations when designing a natatorium. Relative humidity levels,
condensation, air temperature, pool water temperature, pool activity levels, air distribution,
outdoor air, exhaust air, pool water treatment and chloramine control are all vital design aspects
that must be considered in order to deliver a successful facility. This manual will cover all the key
considerations for a successful facility, however, the two most critical design aspects will be
chloramine control and air distribution.
There are new technologies available that will reduce and possibly eliminate chloramines. If an
owner wants to ensure good air quality at their facility, an investment in one of these technologies
is a must. UV water treatment and the Evacuator by Paddock (www.paddockevacuator.com) are
two highly effective technologies for chloramine control. An HVAC designer will rarely deal with
facilities where the overall air distribution is more critical. The treated and conditioned air must
be delivered down into the breathing zone where the patrons are, if there is to be any reasonable
expectation of providing good air quality and a comfortable experience.
