A Group collaboration between classmates (Jun Leong, Htoo Myat Ang, Zheng Rong and Chern Kiat), we developed a digital twin model, with its specification on analysing and balancing different systems (ventilation, lighting and air quality) based on occupancy and interactivity, but also provide predictive independent maintainance and environmnetal monitoring to prepare itself for emergencies, through sensors and BIM management.
