Understanding the Impact of Wind-Driven Rain on Architectural Design: Insights from Windtech's CFD Study Approach

Wind-Driven Rain and Facade Design

Wind-driven rain can affect facade detailing, entrances, balconies, podium areas, and occupant amenity. Windtech studies use local wind climate, rainfall data, building form, and surrounding exposure to identify where rainwater is likely to be driven onto sensitive architectural elements.

CFD analysis allows designers to compare configurations and improve weather protection before details are finalised.

Design Value

The value of this work is strongest when it is introduced early, while canopies, screens, facade articulation, drains, and other protective measures can still be integrated cleanly into the architectural design.
