This paper studies radiant barriers (aluminium foil systems) in attics of buildings in the hot-and-humid climate of Malaysia. Three similar 3x3m test cells were equipped with different configurations of
roof tiles (clay, cement) and radiant barrier foils. The test cells were equipped with data loggers for indoor temperature and relative humidity in the attic and the room below. The local outdoor climate (temperature, relative humidity, solar radiation, wind speed) was measured with a roof mounted weather station. Different natural ventilation options for the attic were realized. The room below the attic was ventilated via passive cooling during night in all cases. The function and effectiveness of configurations with radiant barriers were compared with the baseline case. In general, the results showed no significant difference between the use of
clay and cement roof tiles, while the use of radiant barriers did have some influence on the attic and room temperatures.
