thyssenkrupp is a company with a history stretching back over 200 years and many good traditions. That’s one of the reasons why in 2010 the Group built its new headquarters, the thyssenkrupp quarter, in Essen. Comprising a total of 13 buildings, the open-plan campus is located right next to the Krupp family’s ancestral home. It provides a modern and convenient working environment for employees.
Sustainability is key to our strategy – and to our quarter
Sustainability requirements were taken into account in the planning and realization of the buildings and open spaces.
This is reflected among other things in an efficient energy supply concept, the predominant use of locally available or produced materials, and an energy-efficient heating and cooling system for the buildings.
Office buildings heated by geothermal system
The expected primary energy demand for the office buildings is 20 to 30 percent lower than required by law. To date, few such energy-efficient buildings have been realized in Germany, particularly buildings with large glazed areas.
The thyssenkrupp quarter uses the heat and cold stored in the ground. For this, ground loops were installed at depths of up to 100 meters in the roughly 900 m² “geothermal field”.
The sun protection system gives the main building its “face”
The geothermal system is supported by the external sunshades. Some 400,000 centrally controlled slats provide protection from the sun comparable with conventional external blinds.
The vertical slats have the advantage that they provide much better visibility and remain fully functional even in severe winds.
Before construction work started, the entire site of the quarter was examined for possible legacies from almost 200 years of industrial history. With the assistance of experts, contaminations were professionally disposed of.
On the whole site around 400,000 m² of earth was moved and used among other things for the construction of the Krupp Park. The greening of the quarter site with more than 700 trees is exemplary. Together with the generously dimensioned water axis, they significantly enhance the micro-climate of the entire site.
For the innovative “rainwater separation system” in the quarter, the Emschergenossenschaft water management association presented thyssenkrupp with its “Watermark” award. The “Watermark” honors projects making sustainable use of rainwater.
2/3 of the site is unpaved, allowing most of the rainwater to drain away and be returned to the water cycle. Throughout the quarter, rainwater on the roofs of the buildings (around 25,000 m²) is collected and fed among other things to the lake in the Krupp Park.
