Adverse effects of sopite syndrome on occupants in wind-excited buildings. Current building motion design guidelines focus primarily on motion perception and complaint rates. However, wind-induced building motion can cause sopite syndrome or early onset motion sickness which adversely affects occupant wellbeing and work performance. This research aims to advance the understanding of the physiology of sopite syndrome, quantify the motion dosage that causes sopite syndrome and determine its advers ....Adverse effects of sopite syndrome on occupants in wind-excited buildings. Current building motion design guidelines focus primarily on motion perception and complaint rates. However, wind-induced building motion can cause sopite syndrome or early onset motion sickness which adversely affects occupant wellbeing and work performance. This research aims to advance the understanding of the physiology of sopite syndrome, quantify the motion dosage that causes sopite syndrome and determine its adverse effects on building occupants in real-world motion environments. This knowledge is expected to guide the formulation of building motion acceptability criteria based on safe motion exposure duration to facilitate the design of tall building that promotes population health and wellbeing and lifts work performance and productivity.Read moreRead less
