Comparison of the thermal properties of clay samples as potential walling material for naturally cooled building design
The thermal properties of different clay samples obtainedfrom locations in Akwa Ibom State, Nigeria were investigated andcomppared, and in order to establish their suitability as buildingmaterial from energy conservation point of view. The results showedthat sstoneware clay has the highest solar radiation absorptivityof 22.32 m-1 while kaolin clay has the lowest radiation absoptivityof 14.46 m-1. A model for the prediction of temperature variationwith thickness of the samples was developed. Results showed thatkaolin would make the best choice for the design of a naturallycooled building.
