The property on Kaistraße / Franziusstraße is located in Düsseldorf's Medienhafen. The surrounding area is currently characterized by offices from the creative and media industry and gastronomy. The competition design uses the shape of the meander to generate an opening of the green inner courtyards. This form of building generates high energy saving potentials through the principle of self-shading and thus a reduction of cooling loads. The competition design includes a market hall with gastronomic facilities on the ground floor. Various infrastructures are located above it. The green building joints have air-purifying and sound-absorbing properties. The façade is designed as a permeable and intelligent building envelope. All offices will have openable windows. This allows the building to be supplied with fresh air without mechanical ventilation. The double-shell façade ensures that the windows can be opened even at high wind speeds. From all areas of the building, views into the roof gardens or greened atria are possible. The use of wood in the interior of the building creates positive effects in terms of comfort for the users.
