Fürstenfeldbruck
2017 - 2022
In the west of Fürstenfeldbruck, a publicly subsidized solar housing estate was built with 93 apartments, a community room, tenant gardens and a communal courtyard. Of the 93 apartments, 43 are publicly subsidized. There is a diverse mix of housing types for different household types, for shared housing and for residents with special care needs. Housing types are mixed in all six buildings. At the neighborhood entrance in the northeast, Arbeiterwohlfahrt operates a social center with a community room and café terrace, which will also be available to residents for a variety of uses.
To create a central courtyard for the community and open the residential complex to the adjacent biotope, we developed two three-story polygonal point houses in the southwest. To the north and east, solar-optimized rows shield the complex from emissions from the municipal utility site and street noise. Between the tenant gardens and the communal courtyard are the outbuildings for bicycles, gardening tools and waste.
The buildings were planned in hybrid construction with interior reinforced concrete construction, solid partition walls and a prefabricated building envelope in timber construction. The facades are clad with a mineral glazed formwork made of silver fir. The large balconies are roofed as thermally separated prefabricated steel constructions also on the 2nd floor. The row buildings with their asymmetrically inclined cold roofs are optimized for full-surface occupancy with photovoltaic modules. The outbuildings were designed as wooden constructions with green roofs.
In the highly insulating building envelope, particular attention was paid to reducing energy losses through thermal bridges. The apartments are supplied with municipal district heating via fresh water stations located in the basement. The thermostatic valves of the radiators correspond to the window ventilation; if the windows are permanently tilted, they switch off the radiators. The Isarwatt energy cooperative operates a tenant electricity project in the housing estate. All roofs are extensively covered with a total of 1,460sqm of photovoltaic modules with an output of 279KWp. The power supply is provided by an internal settlement network, so that solar power surpluses can be distributed in a self-consumption-optimized manner. A battery room is provided. All apartments and control elements are digitally connected via a fiber optic network. Some of the underground parking spaces are equipped with connections for electric vehicles. The summer thermal protection is supported by planted trellises on the balconies.
All ground-floor apartments have gardens in front of them, and all multi-story apartments have large balconies. Within the residential complex is the communal garden area connected to the street space with extensively planted meadow areas, playground, fountain and rainwater pumps. Covered areas provide rain-protected outdoor spaces for the community. To the south, residents can cultivate small areas of arable land (grazing land), and here there are also additional plantings, birdhouses, and refuge areas for lizards. From there, the common areas merge into the landscaped area with fruit trees and walking paths.
