‘AirTree’ is an urban sculpture that integrates technology and nature to respond to air pollution in cities. Like a tree, the structure generates an active exchange with the environment by using natural elements—water and moss—to filter particulate matter, and creates a sort of ecological oasis—a new meeting place in the urban context. While making use of solar energy and wind power, “AirTree” provides fresh, cool air during the heat of summer. A color-coded mechanism atop the structure indicates the current quality of the air at the site.
