green wall benefits
A BioTecture green wall
Green walls provide multiple benefits when dealing with the vertical space in urban environments. Many of the world's existing installations appear to be primarily motivated by art, and the visual impact they provide. This is important but we believe there are sound ecological reasons to install green walls:
- reduction of thermal loading to buildings - lower heating and cooling costs = lower carbon emissions
- reduction of heat island effect - less reflected heat
- stormwater attenuation - panels can absorb over 30kgs per m2 of rainwater
- air purification - plants are efficient filters of pollution - especially when used indoors
- noise attenuation - quieter buildings and streets
- increased urban biomass - more green increases all of the above
- ecological habitat increased even with non-native plant species
- positive urban psychology - uplifting effect on those who see it
- positive upgrade (retrofits) to existing urban fabric
