Creating a substrate on walls and roofs to grow plants creates what is known as living walls and roofs. The installation of living walls and roofs can provide many benefits to the building and those who live in and/or own the building. Such as increasing energy efficiency, prolonging the life of building materials, improved air quality and storm water management. They also contribute to adding greenery to cities which increases the aesthetics of the city and makes it a more appealing place to live.
