Dr. Yuan Chao is an assistant professor in the Department of Architecture of National University of Singapore (NUS). Dr. Yuan’s research interests are the climate  sensitive urban planning and design for livable and sustainable cities, focusing on urban aerodynamic properties that is difficult but critical part of high-density urban climate. Dr. Yuan has participated in several key policy-level research projects commissioned by Hong Kong Government, as well as actively involved in a few Chinese (e.g., Wuhan and Macau) projects. He developed the Frontal Area Density understanding, which provides an important knowledge linking the built morphology and the city’s aerodynamic potentials. This work is now incorporated into Hong Kong and Wu Han’s urban climatic research for city planners’ references.
