Interior vertical vegetated green walls improve indoor air quality while exterior living walls lower the buildings heat absorption and provide sound insulation for noise pollution.
When built using native plants, green walls provide a sanctuary for local fauna and help local biodiversity flourish.
Energy used for heating and cooling in large scale buildings contributes to increased greenhouse gas emissions and urban heat island effect. Green walls help mitigate this.
With our growing population and most of us living in cities, edible green walls can be a source of urban food production.
A little different but green rooftops will reduce energy consumption and manage storm water runoff.
