Architectural Wind Visualizations

For architectural competitions, especially for high-rise buildings and landscape architecture and when larger (public) spaces are involved, wind architecture is often part of the requirements for a successful entry. At Rheologic we do not only have the know-how to simulate wind more accurately than the simple algorithms that some 3D drawing applications have included, but can also visualize the results in a number of ways, from rendered stills to full-fledged animations, to give a tangible impression of the air flow, that moves invisibly all around us and is heavily influenced by the built environment.

Wind Flow Visualization

Wind is a force of nature that is hard to grasp with our senses, even more so, when sitting in an office doing architectural planning. However it does have a profound influence on well-being (and safety) when you are in the middle of it. It can be the difference between creating drafty, uncomfortable places and cosy corners with a gentle breeze where people enjoy to linger.

We at Rheologic do have lots of experience to turn our simulations into stunning renders of the wind flow, either as static images or as videos with static or dynamic flow, thus giving visual substance to something that will strongly influence the comfort and safety of the people that will eventually populate the planned environments.

Below you find a number of wind visualization renders that we did for two of our customers for various architectural competitions, specifically Soyka/Silber/Soyka, finalist for Quartier Althan in Vienna, Austria and Progress.Moscow for Admiral Serebryakov Embankment in Novorossiysk, Russia - 2nd place after Zaha Hadid Architects.

Simulation Quality

A basic requirement for the visualization of wind in the built environment is of course the quality of the underlying flow simulation. Even for experts it is often difficult to impossible to guess at a flow or to judge its accuracy just by looking at the visualizations. This is why validation is so important: it allows the engineer to verify that a particular simulation model (of the dozens that are commonly used) and the chosen parameters delivers accurate results for a particular case.

Another question is the number of effects that are included in a model - e.g. does it include buoyancy, accurate vertical wind profiles, ground roughness, ground cover and trees...?

Most simple models do not include these effects, making their results more indications than accurate state-of-the-art flow simulations.

We at Rheologic have lots of experience choosing the right models for any given situation including effects of terrain, surrounding structures, trees & bushes and much more and to hit the sweet spot of simulation accuracy vs. speed of delivery.
