Snowdrift significantly affects human activities in snowy regions. Many experimental studies have been carried out using wind tunnel technique to predict snowdrift around buildings. However, it is very difficult in some cases to satisfy the similarity requirements for wind tunnel studies on snowdrift. Furthermore, wind tunnel equipment is not readily available to many planners, designers, etc. Thus, a numerical method for predicting wind environment and snowdrift is expected to become a useful tool for architectural design and city planning in snowy regions. In this study, CFD (Computational Fluid Dynamics) and CG (Computer Graphics) techniques are applied to the prediction of wind environment and snowdrift around a building complex in Nagaoka City, Niigata Prefecture, Japan.
