Abstract

The use of thicker, comforter type blanket as sleep cover suggests a lower neutral temperature for a subject compared to one that use normal blanket. In hot humid Malaysian climate, this would result in higher cooling load for air conditioners. This study investigates the effect of blanket thickness on occupants' thermal neutrality in air-conditioned bedrooms. A thermal comfort field survey is conducted on the occupants of 36 air conditioned bedrooms in Klang Valley. Thermal neutralities are established using Griffiths method (Griffiths 1990) revised by de Dear and Bragger (de Dear and Brager 2001) . It is found that only 30% of households use comforter type blanket, suggesting the use is by choice rather than necessity. The neutral temperature of households that use comforter type blanket on average is lower by 2.3C than that of households that use normal blanket. The finding suggests that adaptive behavior does not always result in lower energy consumption when active cooling is employed.
