Mexican Building Eats Smog


Mexico City's poor air quality is notorious. The Manuel Gea González Hospital designed by Berlin’s Elegant Embellishments acts as an air filter and neutralizes the equivalent daily of about 9,000 cars. Here's how it works:
 The 2,500-square-meter facade is constructed from the firm’s 3D Prosolve 370e (PDF) modules. These modules are coated with a special pigment that, when hit by ambient ultraviolet light, reacts with urban air pollutants, breaking them down into less noxious compounds like carbon dioxide and water. The pigment itself remains unchanged, which means the modules can keep purifying the air for as long as a decade, or until their coating wears off.
