Work title: inhabited artificial basins for a future city (0000701473)Description:
Sustainable development is the development which "meets the needs of the present without compromising the ability of future generations to meet their own needs." Starting from this fundamental concept, we have analyzed the possible future of the terrestrial planet, especially considering the climate change effects on the world''s population. Global warming, caused by greenhouse gases, is increasing the average temperature of the earth, and will generate ocean enlargement and sea level rise. In Europe it is expected to have rainfall quantity reduction, dry season increasing and desertification in Mediterranean areas. We have decided to analyze the urban borders regarding the needs and demands of future generations, which are expected to square with a catastrophic water emergency and an increasing level of global hunger, caused by lower agricultural outputs in tropical and subtropical zones. Considering a Mediterranean country as our site, the first challenge of the project is the rapid increase of temperature and a great water dearth. It''s fundamental to think about sustainable urban solutions, development of renewable energies, efficient energy use in architecture and sustainable agriculture, to reduce the production of greenhouse gases. The microclimate conditions of the surface will no longer be able to guarantee an appropriate quality of life; the functions that take place above will exclusively be food and energy production, as well as water harvesting. Life will exist below that level, where microclimate conditions will be more habitable and water storage will warrant biodiversity preservation. Buildings will be inhabited artificial basins and their shape will provide water harvesting from roofs into reed beds permitting natural drainage and creating a system of underground channels, as well as natural shade. Terraced structure will ensure green areas and micro urban garden inside the buildings, promoting small-scale processing and limiting heavy transport. Public functions will take place along the displaced ground, as well as around vertical connections. Building shape will favour pedestrian connections and public transport, minimizing the production of greenhouse gases. The project is developed as a mastersection, set up by a stratification of different and specified functions, thats relations take place vertically and no longer horizontally. The presence of a ‘canopy’, acting as a barrier between the hostile solar environment, not only will filter the solar radiation to provide shade below, it also will act as a spoiler to positively redirect the wind and flush heat build up in the public realm below. In providing shade to the buildings the ‘canopy’ eliminates the need for expensive building shading systems, whereas for the public realm the canopy allows controlled amounts of sunlight through for the plants and the water processing reed beds and to provide beneficial external micro-climates.
