Project Overview (2500)
The draft air - earth is a mobile object. In its compact form, it boils down to a volume of 12 m3, which reduces the production of carbon dioxide transport-related material. It is the only Delivery required by the construction process and throughout the useful life of the module. It includes the wooden structure with 48 pallets and 360 linear meters of battens of wood together.
The kit will be accompanied by instructions for use of the land. This training manual will propose a series of test intuitive analysis and adaptive processes of the earth from site construction techniques employed.
Land is the ultimate clean material: it requires no transportation or processing, it is recyclable and biodegradable. Its only shortcoming is the difficulty of its traditional implementations which require manipulation and layout of large volumes of a density greater than 2. The project is looking at ways to mechanize these tasks without increasing the financial and environmental cost. The method of spraying compressed air on a mesh woven of reeds (basketry) offers innovative adaptation of the ancient technique called Quinche.
Beyond its insulating material is a land whose use is intuitive. We work this material as a sculpture by simple aggregation or subtraction. In this sense, the earth, which works by simply stacking, lends itself easily to self-construction. It offers, sandy, high compressive strength and clay, cohesiveness and waterproofing.
The project will combine the one hand, natural materials for elevation: stone, lime, earth, wood, straw, reeds and other recycling of industrial waste: pallets for part of the structure wood, strips of tires for assemblies or packages tetrapack thermo-molded corrugated metal for the cover. This last component will offer a second life to this extremely hazardous material and will also, as with insulation in the state of aluminum.
structure once assembled created a cube of side 5 m and has two trays. Each wall is optional, the chiselling is site, like a variation of Sol Lewitt.
Everyone can choose their architecture and implementation. Finally, the draft air - land also offers the guarantee of a perfect integration into the site since it is made from the raw material available in its midst.
How does your project contribute to sustainable development there? (1500)
We have seen that the proposed air - ground minimizes the movement of materials that require the building process. It proposes the use of natural materials and recycling of materials produced by the food industry.
Earth, natural material, is used by man in construction for thousands of years. Let us remember the Great Wall of China, the pyramids of the Aztec or Moroccan casbah. These books are perennial.
Its transformation into material for housing requiring only little energy and its availability immediately, give it an unqualified success even today. An estimated 30% of homes are built in the world based on earth. Finally, it is a clean material throughout its life cycle: abandoned housing biodegrades.
Moreover, the earth walls provide energy savings. They play a role in storing energy: the m asse heat. addition to its storage capacity, the earth behaves dynamically: it restores the warmth or coolness out of phase. Thus, by varying the thickness of walls and the specific weight of the material, we can optimize the dual role natural air conditioner / heating of the earth wall. Moreover, the earthen wall at the same time regulates the humidity of the air and solves the problems of condensation. Finally, it is a living material and as such the earth reacts as its environment, it integrates perfectly.
