Since it was the only commercial airport in Qatar, the old Doha International Airport suffered from over-utilization. The capacity of the airport stood at 12 million passengers per year and even though the airport had been expanded numerous times it still struggled to cope with the demand, which is now nearing 14 million passengers per year. To seek to alleviate this problem the existing airport has been replaced. The new Doha International Airport is the fourth largest airport in the world, covering 2,200 hectares of land.
Colt worked closely with HOK Architects in San Francisco and New York to match the client’s demands for achieving both an aesthetic and functional solar shading solution for this very large terminal building in the desert. A controllable Colt Shadoglass LS4 system was selected as the most visually pleasing and effective solution.
Approximately 11,400 m2 of such louvre was fitted to the exterior of the building at both the South Node and Concourse.
The Shadoglass louvres offer many benefits apart from their aesthetic impact. They greatly reduce the solar heat gain into the building, thereby both enabling more comfortable conditions and reducing the amount of air conditioning used, thus reducing the building’s running costs.
