Green walls are great for an urban environment as plants reduce overall temperatures of the building. Plant surfaces, do not rise more than 4–5 °C above the ambient and are sometimes cooler. which are particularly suitable for cities, as they allow good use of available vertical surface areas. They are also suitable in arid areas, as the circulating water on a vertical wall is less likely to evaporate than in horizontal gardens.
