The ‘City Respiration Skyscraper’ designed by Czech architects Pavlína Doležalová and Jan Smékal is a helicoidal 240 meter-high structure designed to clean the air of the most polluted cities worldwide. Its primary structure is a concrete ribbon covered by air-cleaning algae. The outer cellular structure is a three-dimensional cluster of individual concrete three-spike units inspired by sea sponges.
This helicoidal structure acts as a chimney where warm and polluted air is captured at the bottom and filtered and oxygenated by the algae and a specialized water-sprayed system. A network of these skyscrapers strategically placed in the most polluted areas could clean a city in a couple of weeks.
What will the skyscrapers of the future look like? Will they be covered in gardens, shaped like rocket ships, submerged in the ocean? eVolo Skyscrapers compiles 300 forward-looking projects, like buildings that incorporate robotics or are capable of flying...the next generation of big buildings.
