There are many air quality concerns and HVAC design challenges associated with indoor pools. Recently, PBA, was tasked with meeting those challenges, for the Michigan State University, East Lansing, MI, IM Sports West Pool / Locker Room HVAC Replacement project.
For the Michigan State University, HVAC natatorium renovation and upgrade project, the design team including MSU, PBA and Novus Environmental, along with other team consultants, were able to make a direct correlation between Trichloramine formation and off-gassing from indoor pools, and the adverse health effects that the gas was having on swimmers, coaches and facility personnel. From that correlation, PBA and its engineering design time were able to provide an effective HVAC design solution to resolve the issue of off-gassing, through a unique ventilation process.
In addition, the application of advanced computational fluid dynamics (CFD) modeling was used for evaluating and improving the HVAC design in the natatorium, and for highlighting conditions under the existing system operation.
