Urban planning solution – interweaving and connecting
The theme of interweaving and connecting is translated into a polygonal structure that links the surrounding city and its open spaces with the new student neighbourhood. The crystalline structures are staggered in height and create differentiated internal and open space qualities. The buildings thus create a permeability into the neighbourhood and enable multi-layered views towards the Inn and the mountain landscape. The design of the building forms in towers and plinths differentiates a clear range of uses for the plinth and roof terraces from that of the towers. While the plinth design provides a clear address and offers space mainly for communal areas and roof terraces, the towers are for residential use.
The open spaces resulting from the shape of the building offer areas with differentiated, high-quality areas to spend time. The Inn promenade and the future Champagne area are generously integrated into the urban development concept. In interaction with the plinth zone, the public space extends upwards into semi-public areas. From here, interesting visual relationships within the site are interwoven with functional relationships between street level, plinth and building. The polygonal layout provides residents with interesting views and perspectives.
Architecture and open space – river landscape
Differentiation in the formulation of the individual towers enables adaptation to the individual functional uses and at the same time provides a response to noise pollution in the form of noise protection loggias. The functional focal points of affordable and subsidised housing are structurally separated from each other, thus enabling permeability in the neighbourhood. Separate economic considerations ensure different marketing options. In the base areas, the public areas are arranged in such a way that, on the one hand, they seal off the noise and enliven the introverted open spaces and, on the other hand, utilise the adjacent public space with its high footfall and enliven it with functions such as the bakery.
The higher development minimises the amount of built-up area on the site. This will result in high-quality, differentiated open spaces with rich fauna that tie in with the existing river landscape. The paved areas should be broken up as far as possible and minimised to the bare minimum. The graded dissolution of paved, semi-paved and green areas prevents overheating in summer and also enables the degree of sealing to be optimised. The organic open space design results from the movement of the river – the green space runs like a river around the buildings and along the Inn. The green islands along the Inn promenade serve as extended park spaces and for programming different uses.
Energy efficiency and sustainability, building technology
A passive house construction method with a highly efficient thermal envelope and controlled living space ventilation can achieve a reduction in the building’s energy requirements compared to the OIBRL 06/ SIA 2024 benchmark. The entire construction phase will be supplied 100% via an anergy network consisting of heat pumps and a geothermal probe field. High-temperature district heating will only be used as a backup or fail-safe measure.
