Anti-smog buildings: Clean air through architecture

Posted by Steve on 02 4, 2008

A new type of architecture is gaining in popularity, thanks to visionaries such as architect Vincent Callebaut that blend design and technology to create a new definition for the term “green building”. Callebaut’s latest project uses green technologies and systems that are more than just examples of sustainable design; the structure actually improves the environment just by sitting there.

Callebaut’s prototype project, being built in Paris, is covered with 250 square meters of solar photovoltaic panels and coated in titanium dioxide (TiO2). The PV system produces electrical energy for the building, with the TiO2 coating working as a catalytic system to clean the air. The TiO2 works with ultraviolet radiation to interact with particulates in the air, break down organics and reduce airborn pollutants and contaminants.

The structure also has a large green space on top for further air purification and rainwater catchment for use within the building. The other part of the building, is a ‘wind tower’, a cylindrical structure that has a spiral pattern that alternates between vertical gardens and embedded vertical axis wind turbines, that generate electricity from prevailing winds.
