Sustainable Structure that Is Invisible to Radar

Share

Coop Himmelb(l)au, an Austrian design company, has come up with its new original concept - a 30-story tower that has a special metal skin which makes the building invisible for the radar. The Town Town tower was proposed to be erected in Vienna near the Vienna Airport.

It is worth mentioning that a tower located close to the airport could interfere with the radar systems, damaging the ability to observe incoming and outgoing aircrafts.

The 3D facets installed on the new tower act as radar scatterers, spreading the incoming waves in various directions but not back to the radar dish, which makes the structure visible for the people walking by but invisible for radars.

At the same time the rippling skin that covers the tower has another advantage - it shades the space inside, being able to regulate the temperature in the offices and cut the level of carbon footprint. According to the design first, the panels of the skin are covered with ultra-thin photovoltaic cells that can produce 264 megawatt-hours of energy per year. Besides, the building has a huge wind turbine at its top. All in all, the structure can produce 2,000 MWh per year. More information on the design is available here.
