This study focuses on the valuation of local materials in order to build economical, sustainable and resilient housing. The objective is to determine the thermal properties of composite bricks made from a mixture of laterite and straw (rice hull and typha) with proportions of between 3 and 6%. The thermal characteristics including conductivity and thermal effusivity were obtained from the hot plane method. The results showed that the addition of straws increases the energy performance of composite bricks. Thus, for 6% of straw, the thermal conductivity decreases by 52%, 53% and 63% respectively for the typha, the rice hull and the typha-rice hull mixture. The thermal effusivity, for 6% of straw, decreases by 45%, 50% and 62% respectively for the typha, the rice hull and the typha-rice hull mixture. This characterization made it possible to show that these bricks have good thermal inertia and high conductivity compared to standard cement-based bricks.
