A vertical forest is expected to be completed this year 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.
Yes. This is how cities should be. Green the cities as one of several steps in making them more habitable, and build up and not out, so that we can free up more lateral space for wildlife again.
