Two Characteristics of Karlsruhe

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.

Urban Trends in Germany

Population shrinks - cities grow Living conditions in urban and rural areas become

equalised Population increasingly mobile Migration: 1) east- west 2) city - suburb One of the most dense transport systems Concept of regional decentralisation

definition of sustainability

„sustainable development is a development, that meets the needs of the present without compromising the ability of future generations to meet their own needs.“ (brundland Report, 1987)

living structures and energy use

why are cities central objects: for the implementation of sustainability?

50% of all energy consumed in europe is used to run buildings

25% of all energy is accounted for by traffic

Eco-Vila Webpage

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)

Minimierung von Flächenversiegelung

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 - Boden

Phase 3:

Minimierung von Flächenversiegelung -> geringe Pfützenbildung -> weniger Krankheitserreger

Anschluss an das Abwassersystem Regenwasser wird gesammelt.

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