"Turbine LÃ¼bbenau - meeting point green center". Urban design and integration into the surrounding open space An independent neighborhood grouped around a green center is formulated, which redefines the guiding principle "living and event in the park". An ensemble of 6 buildings is grouped in a circle around a central open space. The circle also stands as a symbol of community, as a new center in a heterogeneous environment. On the basis and zoning of an "ideal city", a northern residential area, a central residential area, a central neighborhood park (functional area community) and a public part of the event area Turbine will be merged into an overall structure. The linear building structure and formation of a central area, which in turn interlocks with the private outdoor areas, enable the implementation of different forms of living, in which people can live together across generations. High-quality meeting spaces enable an interplay of private and public togetherness. In the the placement of the buildings and the open spaces, great importance was attached to the preservation and and integration of the existing tree population. The ensemble fits into the surrounding park with its trees flowing through the property. The architectural theme of the turbine, as a historical component of the 1950s years, will be further developed and interpreted in a contemporary way. A new ensemble is created through similarities and quotations in cubature, material and facade of the new components. The turbine as a reclaimed place of community The southern faÃ§ade will be renovated in accordance with the preservation order and contemporary solar control glass. The former rear side of the hall will be a community area with linear functions (kiosk, bicycle workshop, washroom). As the second face of the hall, this protruding component acts as a âglowing jointâ to the living area, its polycarbonate facade refers to simple, inexpensive materials from the 1950s years. Two passageways connect the hall, the common area and the living area. The central hall of the turbine, with its new, rounding terrace, continues to be the the venue for a few major events held each year. At the same time the lounge-cafÃ©, which in normal operation is furnished within the quarter, becomes a foyer and entrance and entrÃ©e (party lounge). A continuous use of the hall building in special cases as well as in normal operation is guaranteed. Diverse open space types for community and privacy The open spaces directly assigned to the residential buildings form the core of the open space. The entrance areas in the east are designed as small-scale entrance zones (reception area), while the private gardens on the west side are protected from view with green pergolas. All accesses are made usable as green residential alleys for the residents as a meeting point, the minimized degree of sealing of the surfaces is achieved via barrier-free pavement strips (concrete), lawn paving stones and gravel lawn. Plantable "green borders integrate the houses into the open space. The rainwater that can no longer seep into the surface is fed into the water area in the communal garden. The green roofs increase the degree of evaporation and the biological diversity. The community garden, as the center of the complex, forms an "open" house for all residents and completes the urban footprint of the complex to the ensemble. Energy efficiency (energy concept) The flat roofs will be extensively greened, solar thermal or photovoltaic systems can be installed on all roofs without any problems, the roof surfaces of the two-story components are hidden from view from the apartments. The compact design, the orientation of the opening surfaces towards the sun and the energy supply through climate-neutral sources and, if necessary, connection to an external CHP, if necessary, make it possible to meet even higher KFW subsidy requirements, right up to to achieve the passive house standard.
