Greening Building Enclosure for Improved Footprint: Reducing the Environmental Impact of Green Facades and Living-Wall Systems LWS

This study investigates the ecology and typology of green facades and living wall systems LWS and its significance in improving indoor air quality. LWS has been defined as an air purification method. The potential for reducing inorganic gaseous indoor pollutants, volatile organic compounds (VOCís), and CO2 concentrations have already been proved. Moreover, LWS have also been investigated for the reduction of indoor particulate matters, especially for PM10 and PM2.5, where many studies concluded with significant removal efficiency. Assessment in real indoor environment demonstrated temperature reduction capacity of vertical green systems, which ultimately can be beneficial to lower down the energy requirement for cooling purposes in the buildings.
