CFD & Airflow Analysis
Computational fluid dynamics modelling for airflow, temperature distribution, and pollutant dispersion.
Transient Pedestrian Wind Comfort — CFD
Multi-directional wind analysis showing acceleration zones, wake sheltering, and vortex shedding.
Overview
We use Computational Fluid Dynamics (CFD) to model airflow patterns, temperature distribution, and pollutant dispersion in and around buildings and across masterplan developments — supporting design decisions for natural ventilation, HVAC distribution, outdoor thermal comfort, pedestrian wind environments, and urban heat island mitigation.
Why It Matters
Airflow behaviour is inherently complex and counterintuitive. CFD analysis provides the visual and quantitative evidence needed to validate ventilation strategies, identify dead zones or hot spots, assess wind comfort at pedestrian level, and optimise the placement of air intakes, exhausts, and openings. It is increasingly required for large-scale developments, mixed-use projects, and buildings pursuing advanced sustainability certifications.
Our Approach
We model both internal and external airflow conditions at building and district scale, depending on the project requirement. For interiors, we assess HVAC distribution effectiveness, stratification, and natural ventilation feasibility. For exteriors — including masterplan-scale developments — we evaluate pedestrian-level wind comfort, microclimate conditions, urban heat island effects, and the interaction between building clusters and prevailing wind patterns. At district scale, our studies inform massing decisions, open space design, street orientation, and landscape strategies. Results are presented as clear visual outputs — velocity vectors, temperature contours, and comfort maps — that design teams and master planners can interpret and act on directly.
