The building has a green roof, a crossed-ventilation system, sun breakers and solar control glass, among other elements, all of which help to lower energy consumption. The green roof helps regulate temperatures in the building and harvests and filters rainwater so it can be reused. The roof has two types of plants: native species that don’t require much energy, and CAM (acid metabolism of crasulaceous) plants that promote nocturnal photosynthesis, as well as consuming low levels of energy and water.
