The facade

Designed and constructed by Elegant Embellishments in 2013, the new facade of the Hospital Manuel Gea Gonzalez in Mexico City works actively to remove smog from around the building. The facade is comprised by Prosolve 370e tiles, a material that has a superfine coating of titanium dioxide, a photocatalytic substance that captures and neutralizes the smog particles. This process requires sunlight and, for this reason, the form of the tiles was optimized in order to receive the maximum possible amount of sunlight all along its’ surface. It utilizes a biomimetic pattern, derived from sponges and corals. This pattern was designed using Rhino.

Clusters of tiles were assembled on the ground and then mounted on a vertical grid with other clusters, directly on the facade.
