The “perfect green roof” has been the Holy Grail for architecture until the Hanging Gardens of Babylon. If there is a sustainable prototype, which will provide a truly lush greenery, it could solve a lot of urban problems like urban warming, floods and lack of open spaces. However, recent implementations are not technically or economically satisfying.
Natural water cycle and vegetation are the enemy of the structures (formed of rock or concrete). Suppose that, imitating the vegetation on top of buildings is accomplished; protecting the buildings from that is also required. It’s frustrating. We can notice the failure by seeing no any green roofs around us. Maybe regular cities have enough green spaces among blocks or houses. But especially at the outskirts of the developing cities don’t. Successful green roofs can be life-savers for the millions of people.
Overloads on the structure; water leakage and root attacks against the reinforced concrete (RC) are some hurdles to install the system on a building. To handle it, we must follow the pattern of nature:
Plants are usually vertical structures. Their branches grow up for daylight, roots grow down for water. On the other hand, animals live in burrows, which are lateral structures. Their entries are usually beside of it to control the daylight and air, to avoid rain or other intruders. In ecosystem, both structures live nested peacefully. Human residences had respected that engagement from the Stone Age to Medieval. They excusably expelled other wild animals, and harmful microorganism to create own sterilized hollows. However, the modern cities have broken this agreement. The sterilization brimmed over the hollows to urban areas. In most of city parks, leaves can’t reach daylight among buildings; roots crushed under concretes. Certainly this invasion wouldn’t be unrequited: Urban warming, floods, air pollution and health problems… Insufficient amounts of leaves and roots couldn’t store toxic materials, carbons, water and overheat.
However, RC buildings in modern cities can substitute caves in nature. Of course apartments are the last representatives of animal burrows which access light and air from sidewise. The only missing thing is soil and vegetation on it.
The Craters of Life (COL) explores the pattern of nature. Not only architectural but biological and geological principles are considered in: Obtained 3D pattern ensures root-growing without any concrete-damage; water-discharging without any steel-corrosion. The pneumatic structured drainage is inspired from nature of both planet and metabolism.
Also the manufacture and materials wouldn’t demand high-energy and high-expertise. The COL offers reused/recycled waste materials and simple labor which can be applied by even the habitants. Furthermore, ubiquitous and vacant plastic wastes can provide opportunity to make structures unexpectedly lightweight.
The COL promises a far better waterproofing and thermal comfort than conventional roofs and better attainability than former green roofs. It converts waste, chaos and crowd into a self-sufficient ecosystem, which will provide us larger plants, lush greenery, shelters for bigger critters: real rehabilitations for urban people.
