Urba Wind

The CFD software for urban wind computation and simulation

Wind simulation tailored to the urban microclimate

Wind is a difficult to grasp. In an urbanized environment, its behavior becomes more complex in contact with buildings, and many effects can occur: speed-ups (Venturi effect), vortices, plunging flows, interference, detachments, etc. The built environment thus creates a microclimate that often causes discomfort for users.

To achieve sustainable architecture and urban planning, it is essential to study these aerodynamic phenomena and to integrate them as early as possible in urban projects.

UrbaWind allows you to compute the local wind and model airflows in 3D. It has three modules, each one dedicated to a specific issue:

• Pedestrian wind comfort: its study is more and more requested by project owners in many countries. Its consideration is necessary for the proper development of an outdoor public space and the well-being of users. UrbaWind allows you to compute the wind comfort of pedestrians according to the comfort standards of different countries.
• Natural ventilation: essential to climate construction, it must be taken into account and integrated when designing an energy-efficient building. Natural ventilation guarantee good indoor air temperature, while reducing the use of air conditioning. UrbaWind allows you to optimize the positioning and the nature of the openings.
• Small wind energy: urban wind energy is a renewable energy source that contributes to the energy autonomy of buildings. UrbaWind allows to estimate the potential production and to optimize the small wind turbines positioning.
