Pixel, a 12,300-square-foot, carbon-neutral office building in Melbourne, Australia, is arguably the most sustainable workplace ever. Designed by the architectural firm Studio 505, Pixel captures, cleans, and recycles all of its water on-site. Solar panels and wind turbines on the roof generate all the electricity the building needs. This year, the U.S. Green Building Council awarded it the world’s highest LEED rating—105 out of 110 possible points.
