Biowall for Indoor Air Quality Management
Atif Mustafa,Sadia Khan,Qazi Muneeb Ur Rehman 한국대기환경학회 2021 한국대기환경학회 학술대회논문집 Vol.2021 No.10
Globally, Indoor Air Quality (IAQ) has been recognized as potential risk for dwellers as poor IAQ has a direct impact on overall health and productivity of occupants. With the onset of Covid-19 pandemic people spend 95-99% of their time indoors. Engineering control strategies for IAQ management include ventilation and air purification using filters. Biowall is a botanical air filter that utilizes the natural capability of plants to purify indoor air by reducing pollutants. A biowall was locally designed, fabricated and tested for IAQ management at NED University campus. Indoor air quality can be monitored in real-time and biowall components like fans and pumps can be controlled by application of Internet of Things (IoT). Real-time monitoring includes on-site display of air quality parameters: total volatile organic compounds (TVOCs), carbon dioxide (CO₂), humidity and temperature. The real-time air quality can also be viewed using a specially developed mobile application. Initial results showed that the locally manufactured biowall improved the indoor air quality TVOCs (40% reduction) and CO₂ (5% reduction).
