A wind microclimate analysis provides insight in the pedestrian comfort and safety near high rise buildings. The local wind climate is quantified using amongst others the Lawson criteria or NEN 8100. This is often required during the development of high rise, but also can be executed for existing sites. At One Simulations these analysis are executed using computational fluid dynamics (CFD) simulations.

What do we offer?

It is increasingly more common for local authorities to publish guidelines to assess the wind climate near high rise buildings to ensure a comfortable and safe environment. The City of London has published guidelines to standardize wind comfort assessments. In The Netherlands the national standard NEN 8100 – wind comfort has been published in 2006, which follows a similar approach.

At One Simulations we have developed and extensively used a methodology for analysing pedestrian wind comfort with any set of comfort criteria such as the Lawson criteria, Lawson LDDC criteria, NEN 8100.

With our extensive experience and high-end soft- and hardware, we provide a wind comfort analysis in a short period of time. We can analyze the wind climate during every design phase and for multiple scenarios. For example, we can compare the wind climate in the current situation and for the new development. This can demonstrate that neighboring residents are not negatively affected by the new development. We can support in discussions with the approving bodies or in optimizing/improving the wind climate using, for instance, strategically placed barriers, lamellae or vegetation.
