UrbaWind

The CFD software for automatic wind computation in urban areas.

To calculate the wind energy potential in the cities, the wind-induced natural ventilation in the buildings and the pedestrian comfort maps can be done by UrbaWind which is user-friendly software advanced in fluid numeric's technology, CFD. Specialized software for engineers, architects, designers, city planners etc. to accomplish their projects in minimal time with accurate results.

Recent validation cases

The Bolund blind comparison experiment organized in 2009 at the Risø DTU in Roskilde, Denmark. The results given by UrbaWind have been ranked in the top-10 among 52 CFD models used by wind energy experts, including non-automatic codes.
Validation against measurements done in wind tunnels and in the city of Niigata in Japan by the Architectural Institute of Japan. Presentation at the International Small Wind Conference in Watford, UK in 2009.
