Course Description

Wind is typically the governing load case for façade systems, yet its calculation remains one of the least intuitive tasks in building design. This course walks architects and design professionals through the complete wind calculation process: from basic wind velocity and site terrain roughness through to peak velocity pressure and the application of external and internal pressure coefficients. You’ll learn to determine wind zones on building elevations and roofs, understand how building geometry and surrounding terrain affect local wind pressures, and calculate the design wind loads that govern façade panel sizing, fixing design, and glass thickness selection. The course addresses corner zones, funnel effects between buildings, and the significant differences between pressure and suction loads. Presented by Eugene Korch (façade engineer and IAST Programme Director), the course uses worked examples on real building geometries to demonstrate the full calculation sequence from wind map to final design pressure, including the zoning approach that determines why corner panels need stronger fixings than mid-wall panels. With step-by-step calculation sheets and wind zone diagrams, this course builds confident calculation skills – equipping you to understand wind load reports, verify contractor submissions, and appreciate why getting the wind calculation right is fundamental to everything that follows in façade engineering.
