Radiant cooling by metal roofs in developing countries

Book ·
OSTI ID:379852
In many developing countries corrugated metal roofs are very common. During the nights the roof cools down rather quickly, acting in effect as an effective nocturnal radiator located directly above the living space. However, during the daytime hours the indoor climate in buildings with such roofs is often uncomfortably hot. Installing operable hinged interior insulating plates under the roof can reduce greatly the daytime heating without interfering too much with the cooling effect of such roofs during the nights. A model of this system (a test cell) was built and tested at UCLA. The paper describes the details of the model and its control mechanisms and provides information on the cooling performance of the system.
