Evergreen trees – hence the name – are trees that stay green throughout the year. Italian architect Stefano Boeri is working on a sustainable residential project called “La Tour des Cedres” (The Tower of Cedars), a 117-meter-tall apartment tower in Lausanne, Switzerland. The idea is that these trees, over 100 in total, together with 6,000 shrubs and 18,000 plants, will transform what would be an ordinary 36-story tower into a green space. It will be the first building to be covered exclusively with evergreen trees. The greenery will also protect the apartments from blustery winter winds, dust, and noise pollution. Boeri has designed two similar 110-and 76-meter “Vertical Forests” in Milan. According to the official project [statement][1], these designs will help build a microclimate, produce humidity, absorb carbon dioxide and dust particles, and produce oxygen. This kind of biological architecture, according to Boeri, goes beyond the technical and mechanical approaches to environmental sustainability.
