This pavilion was designed and built for the Milan Expo 2015. Palazzo Italia was conceived as a sustainable energy building almost zero thanks to the contribution of photovoltaic glass in coverage and photocatalytic properties of new concrete for the outer casing. It is an "osmotic" building that dialogues and exchanges energy with its surroundings.The full 9,000m2 of the facade of Palazzo Italia is clad in more than 700 active BIODYNAMIC concrete panels with Italcementi's patented TX Active technology. When the material comes into contact with light, it can "capture" pollution in the air, transforming it into inert salts and reducing smog levels.
