Another example is the combat training pool at the Marine Corps Air Station in Cherry Point, N.C., which has an arched wood ceiling design. Ducts run along the ceiling on either side of the natatorium, providing ample diffusion of supply air with some openings pointed up along the ceiling and others directing flow down into the breathing zone. The pool’s design also demonstrates the importance of using air diffusers with sufficient velocity; this ensures the openings can ‘throw’ the air far enough.
The use of exposed wood framing in indoor pools and aquatic centres is nothing new. Also, a growing demand for green buildings has positioned the material as a powerful and valuable solution for sustainable structure. Not only does it offer design flexibility, but can also be esthetically pleasing if implemented properly.
