and saving costs by cutting down on the unnecessary use of materials.”
The company envisages that its 3D wind modelling will prove invaluable for the many situations where typical wind tunnels cannot provide useful results such as the complex wind interactions of atmospheric turbulence with urban environments, clusters of wind turbines, bridges or airports.

processing the data much faster than the CPU of the PC with only six or eight cores. Vind-Vind’s initial goal for its computer modelling is to assess how the turbulence compares to the measured turbulence over an urban environment. After that, turbulence modelling will be improved to include the effects of a higher section of the atmosphere with wind gusts from different directions. Accurate data gathered in the real world can then be used to verify and validate the predictions of the 3D computer simulation. “With proven accuracy, our 3D wind modelling can be used to provide greater
levels of safety and wind comfort as it will predict the complex nature of the real world, and not the constrained version of the wind tunnel” adds Jorgensen. “Eventually it will mean that the considerable over specification that architects have to build in because of the inaccuracy of wind tunnel models can be reduced. This means improving sustainability
