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.
- These can be incorporated into new building design orretrofitted.
- Continuous or modular structures containing organic orinorganic growth media in which plants are rooted.
- Plants need to be carefully selected to support local pollinatorspecies, and are often selected based on locally rare flowerspecies that were once more abundant to replace dwindlinghabitat for pollinators.
- Pollinator walls often also contain insect ‘hotels’.
- For the system to be sustained, water and nutrients arerequired (which can be supplied using an automatedirrigation system).
IMPLANTATION: Soft/Medium/Hard
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.
AMORTISATION: Short term/Medium term/Long term/No amortization
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.
