1 To obtain a full-year dataset for the total number and size distribution of suspended stack aerosol droplets, and develop a prediction model for suspended faecal aerosols in drainage/vent systems as affected by building height, drainage system design and environmental parameters. 2 To understand the natural ventilation of the full-loop drainage system from manhole to roof vent, and develop a prediction tool for the ventilation and climate in the building drainage system during the non-flushing period by considering heat transfer and the impact of climate and building characteristics. 3 To apply the integrated suspended aerosol and natural ventilation models to analyse the reported COVID-19 outbreaks in high-rise buildings, and provide insights into the fault detection and diagnosis of building drainage systems in terms of leak detection and leak seal
