Fan first integrated stadia bowl construction method

Abstract:

Seating terraces constructed from SPS materials are used to provide integrated HVAC to the seating areas of stadia, arena bowls and similar structures. Portions of the terraces are enclosed from their backsides to provide large ducts or plenums that run beneath the seating terraces where openings into the plenum located between the seats at regular intervals deliver conditioned air to the seating areas. A large header duct runs around the stadium bowl above the top row of seats and delivers air to plenums that run beneath and are integral with the stadium stairways. The seating terrace ducts receive their air supply from the stairway plenums.
