Initially Robert E. (Ed) Cliver, P.E., principal of Estes McClure Associates Inc. (EMA), had designed a generic field-system that combined an air handler using coils coated with an anti-corrosion enamel, a remote condensing unit, and a reheat system that would use compressor heat to warm much of the pool water to 82°F. EMA, a Tyler, TX-based mechanical, electrical, plumbing, and technology (MEPT) engineering firm with hundreds of general school HVAC systems completed throughout Texas, New Mexico, Maryland, Virginia, Oklahoma, and even Mexico, had used a similar dehumidifying strategy in past schools with great success.
Armed with statistical data from other Dallas area indoor pools, Mark McMillan, principal of McMillan Choate, revealed that the natatorium's supply ductwork insulation could be eliminated even though it is a major factor in preventing condensation in the original field-built system design.
