This paper evaluates the thermal performance of building walls in Morocco’s hot and dry climatic zones. Two types of hollow brick walls, namely, single wall (Type A) and double wall (Type B), are examined. The objective is to identify the configuration that offers optimal thermal performance. Numerical simulations are conducted to analyze key thermal parameters, including time lag, decrement factor, and average inside surface heat flux. The results show that the double wall provides better thermal performance than the single wall which can result in lower heating and cooling costs and a more comfortable indoor environment. In fact, the time lag is extended by 5 h and the decrement factor is reduced by 33% for the double wall. On the other hand, a low emissivity covering lowers the overall thermal load during the day, enhancing interior thermal comfort and lowering building energy use.
