Wind Studies for Planning
Planning applications for tall buildings in the urban environment often require a wind microclimate assessment (wind study) to ensure a new development does not adversely affect pedestrian comfort and safety.
Traditionally, such studies could only be undertaken with wind tunnel testing of a scale model, requiring time-consuming model creation and the use of specialised test equipment. However, computer simulation of wind around buildings, exploiting Computational Fluid Dynamics (CFD) technology, is now established as a faster, cheaper and more flexible option. It offers greater insight and enables rapid design changes while satisfying the requirements of local councils and authorities for planning applications
Using industry leading simulation software like Ansys, we regularly undertake qualitative desk studies and full quantitative CFD wind studies considering Lawson criteria, partnering closely with architects, developers, councils, civil & structural engineers and planning consultants to simulate how air flows around new developments. We are familiar with guidelines provided by individual planning authorities, such as the City of London, Sheffield and Leeds, and also write EIA chapters on request.
We have been involved in residential, commercial and student & sheltered accomodation developments in many cities and large towns across the UK and Ireland – from London, Truro, Coventry and Sheffield to Liverpool, Preston, Glasgow and Aberdeen.
Through early involvement in a project while building massing is still flexible (typically RIBA 2 or 3), we can help you avoid expensive last-minute delays in the planning process. This includes analysing the effects of terrain and studying meteorological data, while applying both “real time” and detailed CFD for early identification of potential issues with pedestrian safety and comfort.
Once the wind conditions have been assessed, our engineering team can provide guidance on how to mitigate any issues by landscaping and other measures.

Wind & Rain Loading
By modelling wind flows, we can also investigate the effect of wind loading on structures, through 1-way or 2-way fluid-structure interaction (FSI) capabilities.
We are experienced in helping clients use structural analysis in conjunction with wind flow simulations to design in accordance to relevant codes such as BS EN 1991-1-4 and BS EN 1993-4-1.
Rain can also contribute to arduous loading conditions on buildings. We provide services to assess the exposure of walls to wind-driven rain in line with the BS 8104:1992 code of practice.
Expert Witness & Mentoring
In addition to helping stakeholders with planning applications, we also offer support to councils in developing local wind study guidelines, interpreting quantitative CFD-based reports and assessing third party projects.
Complementary Wind Tunnel Testing
For very tall buildings, some planning authorities require both CFD-based wind studies and wind tunnel tests to be undertaken on the same development. In such cases, we can provide a complete service in association with a wind tunnel partner, practising close collaboration to ensure the geometry and assessment procedures are consistent and compatible.
Prompt and Efficient Quotation Service
Offering a pragmatic yet effective service fine-tuned for design and assessment, we will support you through your planning application with efficient, timely and accurate results.
We always encourage our clients to involve us in their building development as soon as possible since early stage studies can often identify and remedy potential issues before massing is finalised. It can also reduce the overall cost of the assessments required to satisfy planning applications.
