green wall
Related terms: vertical garden
A building or structure facade designed to accommodate substantial living plant growth.
A green wall is a facade of a building or structure which is designed to accommodate substantial plant growth. Environmental benefits include absorption of rainwater, cleaner air, and a reduction of the heat island effect in dense cities.
The facade must be designed to support the plant growth. A green paint color alone does not establish a planted wall.
The feature concerns an exterior wall. Planting on top of a building has the separate green roof arrangement.
