AIR TREE

The city of Madrid soon plans to add a striking new structure that will “climatically transform” its urban architecture. Designed by Urban Ecosystems, the Air Tree pavilion is to be built from recycled materials and will be 100% energy self-sufficient. Using photovoltaic cells, the Air Tree produces a substantial amount of energy, which is then sold back to the local electric companies, the profits being used for maintenance of the structure. The second byproduct is of course oxygen - hence the name ‘Air Tree’!

We’ve written about the Madrid Air-Tree before, when the design ‘Ecoboulevard’ for industrial revitalization won the AR Awards for Spanish Architecture group Urban Ecosystems. Aside from their aesthetic appeal, the trees have a very interesting benefit for the local residents who have to suffer through hot Spanish summers. The surrounding environment near the air tree will be naturally conditioned, reducing the heat island effect found in most city centers. The air trees will be implemented city wide in the coming years.
Furthermore, the structure, made from lightweight recycled materials, can be easily disassembled and moved to another site when needed. This feature makes the entire idea really intruding because dozens of air trees can be installed in cities around major metropolitan areas during summers. The trees will cool the surrounding environments and as a bonus generate clean electricity. If the idea catches on, don’t be surprised to see an air tree in the city near you very soon.
