This paper reports the development of a web-based wind environment simulation and pedestrian wind assessment system using computational fluid dynamics (CFD). Graphical user interfaces were built using Internet browsers to link to the server side CFD programs, which hides the complexity of CFD programs and makes the tool accessible to engineers at the early architectural design stage for quick evaluation of wind field around buildings. The paper describes the system function and architecture, case testing and comparison, and possible future improvement and expansion. ; 國際 ; 20140608~20140612 ; Y ; 紙本 ; Y ; Hamburg, Germany ; DEU
