The improving energy efficiency using unfired clay envelope of housing construction in the south Morocco

Unfired clay is widely used in moroccan's rural areas as a building material especially in the hot an arid climate regions. the unfired clay bricks offer a cost-effective form of construction and are selected for their low environmental impact. in order to valorize this ecological material in building efficiency energy,this work deals with experimental measurements of the thermal diffusivity and the specific heat unfired clay based on the flash method and the use of differential scanning calorimeter,respectively. after,the thermal conductivity can be deduced from a simple formula relating the thermal properties of unfired clay. a residential dwelling constructed using unfired clay bricks was simulated by design builder software with the climate data for south morocco location. this project is devoted to the investigation of the ways to use less energy by showing the impact of using the unfired clay on the thermal comfort and the building energy consumption according to the variation of the outside temperatures. © 2017,university of mohammed 1er oujda morocco.
