Filderklinik acute hospital

The Filderklinik is the largest integrative acute hospital in Baden-Württemberg with an exceptional location directly adjacent to nature. This unique selling point will be further enhanced with the new building. To this end, the basic anthroposophical approach will be translated into a human-oriented and scaled development. Freely arranged houses interlock with the surrounding landscape to promote health and balance body, mind and soul through a holistic approach. To this end, the existing slope is used in the form of an open landscape slab. Intensively greened roof areas develop in continuation of the orchards. Several atriums let daylight into the basement. This creates large, contiguous first floor areas for public and medical use. Above this, the patient rooms, designed in rounded free-form shapes in individual buildings, offer a great view.

Following the principle of "as little supporting structure as possible - as much as necessary", the supporting structure is reduced to wide-span flat slabs, individual columns in a grid of approx. 8 m and the enclosing walls of the stairwell and elevator cores. The flat ceilings are hardly susceptible to vibrations and can also absorb high individual loads from the medical technology thanks to the 2-axial load transfer. The installation routing is completely flexible and the room layout on the floors can be freely selected. This means that restructuring is possible without interfering with the supporting structure. The use of cements with a low clinker content improves the carbon footprint of the load-bearing structure by around 30%. The mass-reduced construction and reduced basic reinforcement save a further 20% CO₂ in the reinforced concrete structure.

The 3-storey base building with the two basement floors and the first floor is designed as a skeleton construction in in-situ concrete. The upper floors are planned as a timber-concrete hybrid construction. The floor slabs are designed as board stacked or cross-laminated timber slabs with concrete topping, while the beams and columns are made of glulam. A flexible skeleton structure is also created on the upper floors, which dispenses with load-bearing timber walls. Proof of fire resistance class R 90 is provided by means of the burn rate. The timber-concrete hybrid construction reduces CO₂ emissions by around 80% compared to a conventional reinforced concrete construction, making the load-bearing structure of the upper floors almost CO₂-neutral.
