Energy

100% self-sufficient
The Energy Tower produces 100% of its own energy demand by itself and only by the power of the sun, the wind and the earth resp. the sea. Hydrogen and hot water tanks store the surplus energy.

Wind turbine crowning the building
The top of the building is crowned by a wind turbine generating ecological wind power. The patented design (patent No.4-06-05-6331) is based on the Darrieus type, a vertically mounted turbine. Its outstanding, flamelike shape turns into a symbol of sustainability and the respectful use of natural resources.

Rotating Solar Shield
A newly developed sun protection device - the Solar Shield - rotates around the building while tracking the sun. It prevents the interior of the building from being heated up by the sun. Semi-transparent photovoltaics mounted to the Solar Shield produce solar power. Additional photovoltaics to cover the building’s power demand are installed on the roof of the Beach Mall at the foot of the building.
