Ventilated walls and “ice house” roofs are the type of construction which consists of interposing additional walls or roof skins between the standard building envelope and the exterior environment. The new skin is separated from the building envelope by an air space which is usually vented to the ambient environment. The primary objective of such construction is to eliminate or drastically reduce the effects of solar loading on the building envelope. Recommendations on applications of new buildings and retrofit of existing structures are presented.
