| The significance of sustainable buildings has grown lately due to the imperative to conserve energy. Buildings consume a substantial portion, approximately 40%, of total energy usage. The surface area of the building facade plays a crucial role in achieving energy efficiency. Particularly in hot climates, the building envelope operates as an obstacle to external climate fluctuations. This study focuses on the impact of the building facade components on the energy and thermal performance of buildings in hot climates. Based on prior studies, it investigates the effect of external wall materials, glazing layers, and insulation materials on buildings energy consumption. The study reviews innovative design approaches and technologies that improve environmental conditions, providing modern and effective solutions to optimize building envelope performance in hot climates. The research utilized designbuilder simulation program to assess the influence of façade wall materials and glazing on energy consumption. Findings demonstrate that selecting appropriate materials and adjusting glazing types significantly impact energy usage. Enhancing thermal properties, u-value and SHGC, can improve the performance of facade materials. Additionally, glazing areas exert substantial influence accounting for approximately 80% of the façade's impact on energy consumption. The results indicate that energy savings are up to 78.4% compared to the base-case. | ||||
