Air circulation in natatoriums is a very crucial part of pool design. Improper design of the HVAC system can lead to respiratory problems for swimmers, lifeguards, or even spectators. Having experienced multiple pools with this issue before has led me to push to investigate this problem further. The focus of my research is to get a better understanding of how air circulation works within a natatorium. This will primarily look at the design elements of natatoriums such as air changes per hour, flow rate, and proper placement of vents for supply and return and see how each function and influences one another during the design process. Secondly testing the air flow of this space will check to see how successful this design can function as a natatorium when in use.
