For the planned zero-energy house of Gerber Architects in the Middle East DS-Plan develops an innovative energy management

With the energy tower Burdsch al-Taka the well-known Architect Eckhard Gerber from Dortmund enters new fields in the building technique. The 322 metres high and 68 floors containing building is planned as a “zero-energy-house” and supposed to generate the necessary energy for cooling and power supply by itself.

The efficient façade and climate concepts support the reduction of energy need in comparison to usual buildings of the same size by around 60 percent. The remaining energy need is gained by regenerative energy sources such as sun, wind and water. Without Stuttgart´s energy managers of DS-Plan, the expert group of the Drees & Sommer Group, the project would be hardly to realise: The energy managers are responsible for the complete technical planning and developed a forward-looking energy concept: Historical Persian wind towers were taken as models for the room conditioning. The basis of the principal is the selection of the building form that cool Northern winds are caught in and directed through the building while warm Southern winds secure that the building is not passed through.
The engineers of DS-Plan transferred this philosophy to a modern building and façade concept by only opening the lee situated facades and therefore the extracted air is dissipated by natural forces. According to the historical model the energy tower only uses pure natural climate techniques.
