Price Solution: Custom Linear Floor Grilles From Price Solve Unique Design Challenge
The four story glass exterior wall of the atrium sweeps around the face of the building in a grand curve. Curved underfloor displacement diffusers are elegantly integrated into the aesthetic
design of the lobby. The diffusers, which are situated where the suspension cables meet the floor, are custom crafted to exacting architectural requirements and blend seamlessly with the space.
Price’s impressive custom capabilities were utilized to design and produce the 100+ feet of specialty curved linear floor grilles that wrap the exterior wall, theaters and staircase. Price
adhered to stringent lead times and collaborated closely with the engineer, architect and contractors to help achieve a stunning and functional result.
The project engineer estimated that conditioning this lobby/atrium area using overhead air distribution would triple or quadruple the air volumes required to maintain the same level of thermal
comfort provided by the displacement air distribution. The use of displacement ventilation significantly increased energy savings within the building when compared to other approaches.
In the performing halls, over 2,200 Price Round Floor Displacement Diffusers (RFDD) are inconspicuously installed beneath the auditorium seats. When the design team began developing the vision
for the facility there were three overriding objectives – reduce energy consumption, maximize patron comfort, and eliminate audible distraction from the heating and cooling system.
The W.L. Cassell engineering team visited the Price Technical Center in Atlanta, GA to view a mock-up of the space and conduct firsthand witness testing.
Originally designed with underfloor swirl diffusers, the design team was concerned that the higher velocity air would cause an uncomfortable draft around patrons' ankles.
The applications team from Price recommended displacement diffusers as an alternative, and during their visit to Price Research Center North, the engineers were able to take off their shoes,
roll up their pant legs and experience firsthand the low velocity air from displacement diffusers. The mock-up gave the design team the opportunity to manipulate air velocities and experience the
relative effects. The team was impressed by the performance of the diffusers, cementing their decision to utilize displacement ventilation on the project.
In addition to comfort, the noise reduction associated with displacement was essential to help meet the acoustical design objectives of the space.
