﻿Displacement ventilation adds to airport efficiency
Displacement air-terminal units from Trox are helping Dublin Airport’s new Terminal 2 achieve high levels of energy efficiency. It is estimated that the 75 000 m2 terminal uses about two-thirds less energy than other equivalent buildings. Trox drew on its recent track record in high-profile transport installations when tendering for the project, which was worth about Eu250 000, including Barajas Airport at Madrid — which won the Stirling Prize for architecture.
The Dublin units are housed in purpose-designed stainless-steel grilles which enhance the aesthetic effects created by the architects.
The new terminal was created by a design team that included Arup, Mace and Pascall+Watson. It will eventually handle 15 million passengers a year.
Trox supplied a range of specially engineered diffusers installed inside architectural stainless-steel grilles. They include units installed around structural columns to hide them, cylindrical and rectangular floor-mounted diffusers. Other diffusers were designed specifically for wall mounting and installation in wall recesses.
During the design phase, the diffusers were extensively tested at Trox’s laboratory in Thetford. They were put through their paces inside the architectural steel covers designed for the building.
