Competition-winning design for new Zagreb terminal
This project was an entry for an international architectural competition held in summer of 2008, requiring a building of 70,000 sq m for 5 million passengers a year, with a possibility of future addition. The master plan required the continuous straight-line airside-landside border. This design satisfied the program and the international jury awarded it with the first prize.
A dynamic roof envelope, which unwraps itself to levitate above the terminal hall generates the free dynamics of the structural net – the flying roof – an iconic expression of the landscape and its relief features as original attributions of the generated architectural form. It reflects a unique blend of both aesthetic phenomena and requirements, which combine environmental, symbolic and historical paradigms of human development with openness to both global principles and the inherent local culture.
On the one hand, the creation of the architectural form relies on the strictly functional philosophy of the complex terminal structure, while on the other the ultimate form is the result of the unique urban landscape and environmental context, which allows for different aesthetic attributions evolving from the green concept denoting the symbolism of the new eco-centric humankind. The roof structure is designed as double-skin; its large ventilated cavity provides considerable ecological benefits.
The manipulation of side roof openings and the power of reversible jet fans in the double-skin create a microclimate inside the roof that can dramatically reduce energy consumption. This is a green airport and a powerhouse as well. Together with the water-wise approach, this energy efficient building design has achieved overall synergy of airport and its surroundings.
