The environmental challenges arising from using traditional construction materials, such as cement, along with their rapid depletion, underscore the necessity of employing environmentally friendly building materials derived from natural resources. In this context, this study presents a comparative analysis of the energy performance of conventional building materials and clay-based materials. Focusing specifically on the Beni Mellal region, adobe bricks reinforced with straw, at weight percentages of 0%, 2%, and 4%, were manufactured. First, the physicochemical properties of the investigated clay were characterized. Subsequently, the thermophysical properties of the fabricated bricks were determined. Annual simulations were conducted using the TRNSYS software, considering a typical meteorological year (TMY) for Beni Mellal City, located in the semi-arid climatic zone. The energy performance of various passive energy efficiency measures was evaluated and discussed, facilitating a thermal analysis to assess the energy needs for heating and cooling inherent to each building material. The results demonstrate that clay bricks, particularly those reinforced with 4% wheat straw, outperform conventional materials in terms of energy efficiency, highlighting their potential for sustainable construction. This study emphasizes the significance of local clay resources and natural reinforcements in enhancing energy efficiency and provides insights into their application in eco-friendly construction practices, thereby contributing to sustainable development goals
