006 Earth and Bamboo Constructions, BaseHabitat Summer School, Austria
A hundred international participants under the supervision of:
- Adobe by Amaco (Lucile Couvrer, Gian Franco Noriega, Dorian Vauzelle)
- Bamboo by Escuela para la Vida (Andrés Bäppler Ramirez Greta Tressera Rubén Darío Bermudez)
- Rammed Earth by Lehm Ton Erde ( Martin Rauch, Dominik Abbrederis)
- Straw and Earth by Naturbauwerk (Stefan Neumann, Yule von Hertell
Along the Workshop various lectures gave the possibility to get different insights to the topic of sustainable construction:
- Andrés Bäppler (Escuela para la Vida): “Challenges of contemporary bamboo Architecture”
- Anna Heringer (architect UNESCO Earthen Architecture): “Handmade Architecture”
- Dominique Gauzin-Müller (chief editor of EcologiK/EK): “Sustainable Architecture - between low and high tech”
- Elias Rubin (s2arch): “Building as an integrative process”
- Helmut Krapmeier (Energy Institute Vorarlberg) “Heating with the sun - cooling with the construction”
- Markus Dobmeier (University of Applied Science Munich): “Live projects for social development”
- Markus Thurnher (Fink Turnher Architects): “Modern timber Architecture - ABZ Salzkammergut”
- Martin Rauch (Lehm Ton Erde): ”Challenges of contemporary earthen Aarchitecture”
- Roland Gnaiger (University of Art and Design Linz): “How change and innovation can take place”
Bamboo:
Starting with a design process was important to better understand the material and its possibilities. The bamboo building was an experiment in testing different bamboo connections and construction techniques. The hall is built with six different trusses and esterilla-roof (bamboo mats). All the designed elements were built on the ground. After finding the right poles they had to be cut and put together. Then the element was lifted up and fixed. The last step was to put on the esterilla roof.
Rammed Earth
We built up a retaining wall along a slope which leads the visitor to a traditional mountain lodge at the plot. The wall includes a long bench and a counter for bbqs.
Silt, clay, soil are natural building materials which occur in different compositions over the World. Silt is made of clay and sand and it develops out of the destruction of other clay parts. In its damp condition, silt is according to its composition, a more or less ductile material that becomes load bearing through air-drying. More than a third of the world‘s population lives in houses, which have been built in silt and rammed earth.
Rammed Earth is a widely used vernacular building technique. Crumbly, soil-damp and relatively lean silt matter is poured in layers into a mould and compressed mechanically. A certain advantage of the rammed earth technique is, that the mixture of silt, sand and gravel often appears in nature and it is perfect for construction. The aim of the workshop was to get an intensive hands-on experience and to gain applied knowledge of this ecological technique.
