“…This configuration will reduce the annual energy consumption of the buildings. The same results were obtained in a previous study on different roof pitch values ranging from 0 • to 45 • construction in the town of Er-Rachidia, where the 30 • pitch presents the best results for construction in the town of Er-Rachidia [14].…”

“…One method to enhance energy efficiency in the residential sector involves incorporating bio-composite elements with insulating materials into building construction [10][11][12][13]. In this context, Lamrani et al [14,15] predicted and optimized the thermal performance of two types of buildings built with different wall materials in the south-eastern region of Morocco. The results showed that a building based on clay and traditional building materials offered better thermal and energy comfort than a brick building, and it reduced the annual energy consumption by 27%.…”

“…Several numerical and experimental studies have been conducted on reducing this load by improving roof insulation [25,26]. For example, Rong et al [27] found that using a heat-reflecting material as roof insulation could save 12.9% of the annual energy consumption and reduce the temperature of the outer surface of the roof by 6-8 • C. In a study comparing the installation of a roof pitched at 15 • , 30 • and 45 • to the south and north with a horizontal roof construction, it was found that a roof pitched at 30 • to the south gives the best results in terms of energy efficiency and thermal performance, with a 9% reduction in the total energy consumption [14]. In addition, Amrani et al [28] studied the influence of a heating block, which acts as a radiator installed in the attic.…”

In this paper, a thermal performance assessment of traditional building constructions and configurations in various Moroccan climates is carried out. This research focuses on enhancing conventional energy efficiency of buildings by investigating the thermal behavior of single clay walls, double clay walls, simple brick walls, and double brick walls based on long-term meteorological data using TRNSYS software. The roof pitch, thermal comfort and discomfort index, and building energy consumption are considered while selecting buildings for each temperature zone. It is noticed that the double brick construction is more efficient in all climatic zones of Morocco. Thus, this material reduces the yearly energy requirement of building by 22% to 25% compared to the usual brick building. On the coldest winter days, a 30° south-facing roof raises the internal temperature by 2.5 °C compared to a horizontal roof. Temperature increases could reduce the air conditioning energy usage by 7% to 32% and overcooling hours by 12% to 21% in cities above 30° N. In addition, the findings are interesting enough to inspire individuals to implement the recommended construction design and study energy efficiency and thermal comfort in Moroccan buildings. Consequently, reducing energy consumption, mitigating climate change, and lowering greenhouse gas emissions.

“…The thermal conductivity of clay is around 0.512 W/m.k, which is considered relatively low. Thanks to its low thermal conductivity, clay can reduce energy consumption in buildings by up to 27% [2][3][4]. Reinforcing clay with palm waste can reduce its thermal conductivity and improve its performance as an insulating material [5][6][7][8].…”

In this study, the thermal behaviour of insulating building walls and energy savings were determined in Er-Rachidia, located in south-east Morocco. Specifically, the study evaluates the effectiveness of clay-based insulation materials reinforced with palm leaves pinnate (PLP) and clay and palm trunk (PT). The results indicate that a 4 cm thick clay insulation material reinforced with PLP increases the winter temperature by 1°C and decreases it by 0.9°C in summer compared to room temperature. Furthermore, it demonstrates a remarkable 33% reduction in heating consumption and a 44% reduction in air-conditioning consumption, leading to an overall 35% reduction in total energy consumption. In contrast, the clay and PT reinforced clay insulation materials exhibit a 16% and 21% reduction in energy consumption, respectively.
