Vegetated ‘green’ or ‘living’ walls, supporting flowering plants, whichcan provide nectar and pollen to attract foraging insect pollinator species. Useful in urban areas when verges and open spaces are limited.
Green façades usually do not require any extra structural requirements. They are most commonly attached to concrete walls, but can attach to almost anything, or even be free-standing. We can remove this NBS easily if we want.
Green façades get the recovery of the investment between the 10 and the 20 years. This amortization is related to energy saving, it is not related to the increase in pollinators.
