Building envelope failures rarely happen by accident. They are the predictable result of environmental forces acting on materials and assemblies over time. This session explores building envelope deterioration from first principles. Exterior walls and roofs must simultaneously manage environmental loads such as water, air, vapor, heat, radiation, noise, and fire while maintaining structural capacity and long-term durability. Over time, these demands gradually exceed the capacity of materials, assemblies, and detailing. Using practical case studies, the presentation demonstrates how these mechanisms
