A vertical forest is nearing completion in Milan. There are two tower apartment complexes which contain a total of 400 residential units. The facade of the buildings will be covered with 730 trees, 5,000 shrubs, and 11,000 perennial plants. It is expected to have the same ecological impact as 10,000 square meters of forest. Aside from fighting smog and producing oxygen, the foliage is expected to provide insulation to the residential units.
