City air is full of pollutants and smog that can cause a slew of health problems. But there is one way to help rid cityscapes of this unfiltered air. The folks over at Nemesi & Partners want to change that by bringing an air purifying facade to Palazzo Italia in Milan for the Milan Expo 2015. The purifier will be made from cement and a photovoltaic glass rooftop in order to generate solar energy. The finished product will be over 9,000 square meters and require approximately 2,000 tons of air-purifying cement from Italcementi to complete. 

"The entire outdoor surface and part of the interiors will consist of i.active Biodynamic cement panels," Itacementi said. "In direct sunlight, the active principle contained in the material 'captures' certain pollutants present in the air and converts them into inert salts, helping to purify the atmosphere from smog."

The majority of the cement used to make the purifier will be made from recycled materials, including marble scraps. The architects behind the design want to structure to resemble an urban jungle, with the building taking over the role of trees in a city setting. 

"The overall concept of the architectural design of the Italian Pavilion is that of an urban forest in which the building, through its skin and its volumetric arrangement, takes on the features of an architectural landscape," says Nemesi & Partners. "The branching pattern of the external cladding of Palazzo Italia coherently interprets the theme of the tree of life, inserting it in the form of a petrified forest."

They are also hoping to make the purifier a permanent feature of Palazzo Italia after the expo.
