Abstract:

KEY RESEARCH HIGHLIGHTS Operational parameters of the Junglefy Breathing Wall system were determined and characterised. Data collected included system water loss, pressure drop, air distribution and the system’s effect on ambient temperature and relative humidity. Clean air delivery rates were calculated utilising the removal efficiencies. The system produced 25.86¬–28.70 m3/h per module, depending on particle size and airflow rate. A typical Breathing Wall of 10 m2, utilising 40 modules would thus produce up to 12,700 m3/h of particle-free air. Tests were conducted to identify the most appropriate plant species for survival in high pollution environments. All of the plant species tested, which are currently used in commercial applications of the Breathing Wall, recorded moderate air pollutant tolerance, and thus the system using the current plant species could possibly be used in industrial applications. Pollutant effect on air filled porosity of the substrate was negligible, even under extremely high pollutant loads. Air quality tests were conducted at the Lend Lease Head Office, and the efficiency of the first Breathing Wall installation was monitored. The Breathing Wall is successfully reducing ambient particulate matter and carbon dioxide relative to outdoors and other areas throughout the building. Additionally, air pollutants including carbon monoxide, volatile organic compounds and sulphur dioxide were below the detection limit of the equipment being used, indicating excellent indoor environmental quality. The results indicate that the Breathing Wall is working as intended.
