UrbaWind

Assess wind flow and resource in urban areas

UrbaWind is a wind flow modeling software especially developed for urban areas and green building. The Pedestrian wind comfort module is dedicated to architects, urban planners, sustainable and environmental engineers. It determines areas of possible wind discomfort to make safe and comfortable urban environments around buildings.

The Natural Ventilation module is dedicated to architects, HVAC engineers and designers. It estimates natural air ventilation inside buildings to design bio-climatic, passive and high-performance buildings. The Energy resource module is dedicated to small wind developers, sustainable consultants and turbines manufacturers. It computes on-site wind potential and validates wind turbine location to optimize production and lifetime of machinery.

Environmental urban planning, green building and urban renewable projects


Pedestrian wind comfort

The buildings arrangement can create unwanted local aerodynamics effects: accelerations at building corners, whirlwinds or accelerations between 2 buildings (Wise or Venturi effects) UrbaWind Pedestrian wind comfort module, uses regional wind statistics, evaluates the local climatology inside the plan, computes the exceeding frequency of wind gusts and produces seasonal or yearly maps of wind or solar radiation.

Natural ventilation of buildings

For ecological and economic reasons, it is beneficiary to take advantage of the wind as a driving force or an element of the buildings ventilation for the cooling and renewal of the indoor air. However, the constant change in conditions (year seasons and day or night) of the natural ventilation, its dependence on topography, ground roughness and nearby buildings require a quantitative approach which uses numerical computation and modeling of the physical variables. Urbawind Natural Ventilation module estimates the potential for natural ventilation, computes air renewal rate, optimizes the master plan and the openings characteristics. Finally, it quantifies the flow rate of air renewal and delivers climatological reference data for thermal simulations.

Wind energy assessment

Wind energy production in urban environments, requires an accurate assessment of air flow in
order to evaluate wind resource and risk evaluation due to the complex geometrical environment. The UrbaWind Energy module evaluates the yearly expected production and gives you the key information to choose the best equipment and the highest production locations.

Assets

  • Accurate CFD computations for any structure.
  • Automatic meshing refinement at interest points. The unstructured and multi-grid solver guarantee this accuracy as well as the convergence.
  • Unrivaled calculation speed thanks to the “unstructured MIGAL” solver and the modeling choices.
  • Consideration of the environment (topography, roughness and vegetation).
  • Easy project management thanks to a user-friendly graphical interface.
  • High-quality support ensured by our experts to help our clients at each step of their projects.
  • Regular updates and developments to attain the user’s needs.
  • Specific modules to meet specific requirements.

Options

Multiple processors cores

2, 4 or 63 computer processor cores. The software has the ability to run several directional computations at the same time reducing your computation time from 2 to 8 depending on the configuration.
