A chilled beam is a type of HVAC system that passes water through a beam, causing the beam to chill the air around it. As a result, the surrounding air becomes denser and falls to the ground (remember: hot air rises, cool air falls). This flow creates a constant flow of air that keeps the room cool. Chilled beams result in reduced amount of ductwork and smaller air handler units, thus reducing the space between floors. Chilled beam systems are significantly quieter than conventional HVAC systems, and on average, reduce the facility’s energy use by 30%.
