The projected deposition and removal of particulate matter by green façade drapes: a case study at SAINTGITS.

Abstract

The hazardous sub-micron particulate matter (PM2.5) that goes deep in to the respiratory system causes significant threat to the life expectancy of humans. The atmospheric wind and the diurnal dry bulb temperature are the main factors which govern the pollutant dispersion. This work quantifies the wind assisted deposition of PM2.5 and the natural atmospheric cleansing by a massive green façade drape. The proposed leaf foliage covers the entire South and the West facing walls of a six storied built structure (Visvesvaraya Block) at SAINTGITS, a prominent Technological Institution at Kottayam, Kerala State, India. Whilst the south blowing winds assist the deposition of PM2.5 on to the façade foliage, the removal rate of the pollutants is directly proportional to the stomata opening and the humidity. This case study clearly depicts the natural capability of green façade retrofits to cleanse the atmosphere, thus helps to attain one of the seventeen Sustainable Development Goals (SDGs) of UN.

“…The campus encourages sustainable research initiatives that address one of the seventeen Sustainable Development Goals (SDG) of the United Nations, the SDG 11: Sustainable Cities and Communities. A few of the research activities at SAINTGITS include the energy analyses of in-house built structures, quantification of the environmental benefits of Green Facades and the atmospheric cleansing capability of Green retrofits [22][23][24][25].…”
