The Impact of Exterior Walls Materials on Energy Consumption in a Domestic House in Desert Climate

The purpose of this scientific article is the study of the impact of the exterior walls materials of a house in a desert climate on its annual energy needs in terms of heating and cooling essentially, but also on its internal and solar energy gains and its losses in relation with infiltration, transmission and ventilation. In this regard, simulations were carried out with five different locally used materials. The final purpose is to determine the suitable exterior materials for dwellings in the desert geographical area for energy saving while guaranteeing the thermal comfort. Based on our analysis, it was revealed that a good choice of exterior walls materials can save a considerable amount of energy throughout its life cycle.
