AbstractHeat , air and moisture transport across a building envelope are in-separable phenomena. Each influences the others and is influenced by all the materials contained within the building envelope. Often we simplify the process of architectural design by relating control of each phenomenon to a particular material. The thermal insulation, for example, is perceived to control heat transfer and the air barrier to control air leakage. Likewise, the rain screen and the vapour barrier eliminate ingress of moisture to materials. However, these materials perform many different and interrelated functions, and frequently participate as one of several factors in overall system performance.
