Abstract: There is a need to proffer solution to the relatively high temperature being experienced in various residential buildings, especially in the tropics. The kind of building material being used are of paramount importance when considering how to reduce heat passage from the ambient into the indoors of the residences. This research considered brick material among other building material. Therefore, there was an examination of thermal heat transfer rate comparison between rice husk ash brick and the popular sand crete brick. To achieve this, a 9 inches (230mm) Rice Husk Ash Block was produced (50% of cement content of the normal 100% cement block was replaced with RHA) and compared to the popular full cement 9 inches (230mm) block. Thermal Measurements were taken at the heights of 3.5cm and 23cm. At 3.5cm height, RHA brick has maximum temperature of 260C while full cement block has 440C. The minimum values at 3.5cm were 30C for RHA block and 130C full cement block. At 23cm above the burning side of the block, the mean temperature of RHA and full cement blocks was 1.3333 and 4.6667 and the maximum value were 3 and 100C. Paired sample test showed there is significant difference between the RHA and Full cement block.
