The BRANZ research organisation investigated the environmental implications of 51 alternative archetype window and door systems commonly available in the Australian domestic market, and modelled their thermal performance for a wide range of Australian climates. The study considered the materials used, their production, manufacture and transport, operation and maintenance, durability and life-span and the heating or cooling energy needed to maintain comfort.
