Sports Arena

Sports arenas are typically enclosed high-bay long-span centers buildings that can accommodate a wide variety of sports functions. Stadiums are typically not enclosed, except for the press suites, sponsor suites, and enclosed restaurant and lounge areas overlooking the arena, and an enclosed grandstand at some racetracks.

HVAC system flexibility is obviously key. High volume ventilation systems may be satisfactory. Multiple speed fans are often considered, but the performance of air diffusers and the cooling system at low fan speed must be factored into the design. Air-supported structures require continuous fan operation to keep them inflated. Locker rooms should be very well ventilated. To maintain air balance, locker rooms should have separate supply and exhaust systems. These buildings typically use a multiplicity of air-handling units served from a central chilled/hot water plant to serve the wide HVAC load variations. All-air systems with multiple speed fans and/or VAV systems are commonly used, with provision for operating with 100% outdoor air. Provisions for direct exhaust are also made to accommodate situations where trucks are in the hall loading or unloading and when odorous events are in progress. The concourse areas and their concession stands are heavily populated during entrance, intermission, and exit times. Considerable ventilation is needed to offset the many odors and heavy smoking that are prevalent. Ticket offices, office and restaurant spaces operate at higher and differing hours from the main arena and should be supplied by separate systems such as individual air-handlers, roof-top units or from a VAV system.

Because sports arenas serve a wide variety of events and encompass many separately controlled areas along with general event areas, many opportunities exist to improve indoor air quality.
