Air Permeability Assumptions for Examples

Examples C1, C2, C5 and C6 assume measured air permeability greater than 5 m³/(h·m²), while examples C3, C4, C7 and C8 assume design air permeability equal to or less than 3 m³/(h·m²).

It has been assumed that the intended measured air permeability is greater than 5 m3/(h.m2) in examples C1, C2, C5 and C6, and the design air permeability is equal to or less than 3 m3/(h.m2) in examples C3, C4, C7 and C8.
