Wind microclimate

Assessment of pedestrian wind comfort and safety & Preparing Environmental Statement (ES chapter)

The airflow pattern around a building depends on the characteristics of the approaching wind over its surroundings and on the massing, shape and orientation of the building itself. A building which is substantially taller than its surroundings forms a large obstruction to the approaching wind and can cause uncomfortable and/or unsafe wind conditions at pedestrian level.

It is highly recommended to address any wind related issues in the early stages of the design process, to avoid problems in a later stage.
A wind microclimate assessment according to the official local guidelines can be obligatory for planning application.

A wind microclimate assessment can be obligatory for planning application, but it is highly recommended to address any wind related issues in the early stages of the design process, to avoid problems in a later stage.

Assessment of pedestrian wind comfort and safety

for both individual buildings and large-scale masterplans:

  • Expert opinion / desk study: Qualitative assessment for an early design phase. Based on our experience in wind and the local meteorological data, we advise on likely effects of a new development on the pedestrian comfort and safety levels.

  • Quick scan: Quantitative assessment through Computational Fluid Dynamics (CFD) for an early design phase. The proposed development and its immediate surroundings are modelled as simple volumes.

  • Online wind tool: Use our online platform to perform a quick scan yourself. Our support is available, if required. Check out www.windtool.com.

  • Wind tunnel testing: High quality wind tunnel testing based on official wind microclimate guidelines (i.e. for City of London or Leeds). Suitable for planning applications.

  • Full CFD assessment: High quality CFD study using state-of-the-art methodology based on official wind microclimate guidelines (i.e. City of London or Leeds). Suitable for planning applications.

Preparing Environmental Statement (ES chapter):

Post wind assessment, we help planning consultants to prepare the Environmental Statement (wind chapter) for the planning application.

Overview Actiflow wind studies 

On the map below you find all our wind assessments. By zooming in you go to the specific location and / or project.
Areas with multiple developments show a greater number of wind studies. Actiflow has a great deal of prior knowledge of the local wind climate and requirements set by municipalities in these regions. This allows us to provide detailed advice on a project without even having to perform an actual wind assessment.
