How do we cope with extreme wind incurred by buildings along shoreline in typhoon prone region ?

Recent urbanization around globe shows tendency of high-rise buildings along the shoreline for many reasons, and South Korea is no exception. In spite of socio-economical gains from these development, the downside is so-called building wind, in particular, during the extreme wind in typhoon season, which often threats the livelihood during The realization of hazard has been damage to the structural integrity of the buildings, the threats to the pedestrian safety, and even higher risk due to the wind-borne debris. Another serious impacts are imposed on the existing and aged structures surrounding the newly developed region. Because those structures were built without consideration of additional building wind, they are seriously vulnerable to the newly emerged hazard. Since the urbanization near shoreline will be further accelerating, the problems at hand will be even worse in the future considering climate change. As a proactive measure to reduce and cope with the risk incurred by the building winds, it is important to improve the wind environment in the urban area by evaluating the local climate around buildings. One of recent development of the measures is the utilization of computational fluid dynamics (CFD) method to evaluate wind environment around buildings. With these computational approach, it would be possible to produce the engineered solution to the problems in the future.
