            The German City of Karlsruhe is renowned on a world-wide
             scale for two of its characteristics.
            On one hand we have its fan-like urban structure stemming
             from the absolutistic worldviews of its founders.
            On the other hand there is the quite recent development of
             one of the most comprehensive and innovative urban transit
             systems which connect the central city to a greater urban
             region.

    This Website documents the results of a cooperation between the lab
     for town planning in the global context (GLORA), of the college group
     Engineers without borders (EWB) at the Universität Karlsruhe as well
     as the Pontificia Universidade Catlica do Parana (Curitiba).
    The objective was to improve the quality of live for the inhabitants of
     a poor quarter by the way of a resettlement scheme.
    The resettlement project „Building for the Community” sought to
     develop a new housing estate by involving the population. Innovative
     and recycled materials played an important role.
    The available pages are used for the documentation of model like
     propositions of an ecological settlement planning and should be seen
     as a basis for further projects.

    We sought to develop an ecological low-cost settlement for 25
     families in a periphery location before the town gates of Curitiba.
    Small groups (2-4 students) worked on the task of a town urban
     planning sceme or with a focus on the building structure.
    The specific character of a simulation game was the particular
     feature of this design exercise. Three types of cards were offered:
    a) Cards with handicaps to the ecological livelihoods (i.e. recycling or
     urban agriculture or
             tourism)
    b) Cards with risk factors (i.e. storm, high water, earth quakes etc.)
    c) Cards with handicaps for the building-material and kind of
     construction (i.e. bamboo-, clay- or brick construction)

                      Erhalt der natürlichen Leistungsfähigkeit des Bodens, Minimierung der Bodenbewegung, -verdichtung.

                      Das Schmutzwasser, das auf der nahe liegenden Autobahn anfällt wird in einem Mulden-Rigolen-System
                      gefiltert und gereinigt dem Boden zugeführt

 Phase 3: Gesundheit - Wasser

                      Minimierung von Flächenversiegelung -> geringe Pfützenbildung -> weniger Krankheitserreger

                      Regenwasser wird gesammelt.

                      Jedes Haus wir mit einem aus Abfallprodukten (PET Flaschen, Schlauch)
                      hergestellten Solarkollektor ausgestattet.
