Wind Analysis

GIA offer High Resolution CFD Wind Analysis, providing a faster more flexible and potentially more accurate approach

GIA Surveyors provide Wind Microclimate Assessments to test and identify wind flows quickly and cost effectively, using a digital modelling technique known as Computational Fluid Dynamics (CFD) analysis.

CFD predicts a buildings local airflow and quickly highlights any areas of pedestrian or vehicular danger or discomfort.

We can also provide physical wind tunnel testing, and will ensure that whichever method used is the correct one to enable a smooth path through the planning process at maximum cost effectiveness.

With greater density in cities and buildings becoming taller to help meet targets for our growing population, wind microclimate assessments are becoming an essential part of the planning process.

Ultimately our role is to help you create more comfortable urban habitats.

Microclimate Assessments

Our Wind Microclimate packages are suitable from early concept development, through to planning and pre-building sign off: from single building to large scale masterplanning.

We will guide you through the entire process, ensuring all wind planning requirements are met and that any mitigation that is required is sympathetic to the overall design of the scheme.

Early Massing Studies

The application of high resolution CFD modelling early in the design and planning process, (rather than an afterthought), enables our clients to have greater control within their urban developments.

The commercial and innovative mitigation solutions, developed in tune with the building – promotes a more efficient development journey – saving on considerable time and costs.

Outdoor Thermal Comfort

The “feels like” temperature experienced in an outdoor setting will be dependent on the combination of wind chill and solar heating.

We can provide an outdoor thermal comfort study, which combines modelling of both of these to inform on how much of the year any parks, seating, terraces or entrances will be usable.


Good wind microclimate conditions are necessary for creating outstanding public spaces: adverse wind effects can reduce the quality and usability of outdoor areas, and lead to safety concerns in extreme cases.

With the existing tower cluster that makes up the London city skyline, set to grow further, the City of London have published general guidelines for wind microclimate studies, now required as part of the planning application for new development proposals.
