The visually striking new terminal at Dublin Airport was created for Dublin Airport Authority (DAA) by a design team including Arup, Mace and architects Pascall+Watson. Opened officially in November 2010, it will eventually have the capacity to handle 15 million passengers per year, both short and long-haul. It is already being heralded as a landmark building, receiving a Structural Steel Design Award and being named Public Building of the Year.
TROX was selected to design and supply new air terminal units to help achieve strict energy efficiency and carbon reduction requirements.
Working in close cooperation with the architect, consultant and contractor, P J Hegarty, TROX supplied a range of specially engineered internal diffusers which sit inside purpose-made architectural stainless steel grilles.
They include column units, designed to be mounted around the structural columns to hide them, in addition to cylindrical and rectangular floor-mounted diffusers. Other TROX diffusers have been designed specifically for wall mounting, and for installation in wall recesses.
During the design phase, the diffusers underwent extensive testing at TROX’s laboratory in Thetford. They were fitted into the exact architectural steel covers designed for the building, to analyse and prove performance of the equipment prior to installation on site.
The end result is seamless integration between the aesthetic impact of the space and its building services, with the stainless steel external structures for the diffusers enhancing the space.
As displacement is possibly the most energy efficient way of cooling large open spaces such as airports, the choice of technology has also enabled the DAA to make significant improvements in terms of carbon reduction as well as achieve outstanding levels of energy efficiency.
The 75,000m2 terminal uses approximately two thirds less energy compared to other equivalent buildings.
