b'12 BOS TERMINALSWhile bold architectural choices can include sizable challenges, they also can bring new opportunities. One at BOS involved regulating temperatures in Terminal Es Great Hall, where 60-foot-high ceilings foster large volumes of stagnant air. Arora Engineers consequently recommended a custom-built displacement ventilation system that uses a slow-moving stream of fresh air dispersed at the buildings floors. In a normal HVAC system, youre mixing up all the air up to the ceiling, trying to heat or cool the entire volume within a space, explains James Falvey, a New England-based vice president for Arora Engineers. With displacement ventilation, you let the natural heat rise, and the cooling air stays closer to the floor.An array of 7-foot-tall totems hide HVACJAMES FALVEYcomponents amid holdroom fixtures and elsewhere within the Great Hall. Designers integrated fire alarms, carbon dioxide monitors and select security features near floor level for ease of access and maintenance, leaving only fire suppression sprinklers in the ceiling fixtures.Two decades ago, Terminal A at BOS became the first airport A custom displacement ventilation system helps controlterminal in the world to achieve LEED certification from the U.S. Green temperatures in passenger areas while reducing energyBuilding Council.
