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.
Build up, not out. This is so important. In plenty of suburbs in America, there are laws restricting buildings taller than one story. Think of how much space we could save if we just put the fast food joints and chain stores on top of each other instead of next to each other. It would reduce dependence on cars, reduce the need for building materials, energy usage, and so much more.
