The Solution: Price Designs Custom Displacement Ventilation System
The high ceilings of T2 meant that Displacement Ventilation (DV) would be an ideal solution, providing the ability to condition only the occupied zone and not the large space above it.
This approach reduces the supply air volume required, allowing the mechanical equipment servicing the space to be downsized, thereby reducing utility costs.
The higher supply air temperature of DV (around 65 °F or 18 °C) also enables the building to utilize economizer hours to take advantage of “free cooling,” which further improves energy
efficiency by enabling the HVAC system to increase the outdoor air supplied to the space when the outdoor environment compliments the goals of the air distribution system.
These energy savings were critical to the terminal achieving its sustainable design goals and LEED targets. LEED points were also awarded for the high levels of thermal comfort and air quality
provided by the DV system.
The architectural firm, Gensler, had previously collaborated with Price and Norman S. Wright to develop custom displacement diffusers for the Terminal B Concourse at San Jose Mineta International
Airport (see the Price case study library for a summary of this project). Armed with a new vision, the firms again collaborated to design diffusers that would complement the aesthetic of the new
terminal and presented their solution to the owner.
By working closely together they developed multiple iterations of designs and prototypes, ultimately resulting in lab tests to ensure that performance was in no way impaired by the custom
architectural coverings, specialized geometry and finishes.
Price validated the performance of these custom solutions at the state-of-the-art testing facilities at Price Research Center North. Smoke test videos demonstrated to the entire
design team that the performance of the displacement diffusers is in no way hindered by the enhancements. Satisfied that the custom diffusers would perform as expected and integrate well
into the design of the terminal, the team approved them for installation.
Since reopening, the terminal has provided a fresh and comfortable experience for travelers, with Price’s Displacement Diffusers continuing to play a key role in the building’s long-term
