Cooling effect on building and environment

Studies have shown that greening facades “provide cooling potential on the building surface” (Sheweka). Up to 15 degrees lower temperatures have been found on greened facades compared to bare walls (Hoelscher). Up to 10% less heat is felt around green facades, resulting in an improvement in thermal comfort for pedestrians and citizens (Zölch et al).

While the benefits of urban heat island reduction have just been highlighted, the support of local biodiversity, the purifying properties of plants and the reduced risk of flooding should not be forgotten when talking about vertical greening.
