Due to the vast development in construction in hot-arid climate areas, implementing innovative facade technologies is crucial to meet owners and developer needs, and to meet climate conditions requirements. Buildings are major contributors of energy consumption due to the high glazing areas and their role of increasing cooling demand. Double skin facades are used in cold and temperate climates to reduce heating loads and for other benefits; however, it's believed that a double skin facade can reduce cooling loads in hot-arid climates. This research project aims to find optimized configurations for double skin facades in this climate. Therefore, by implementing fully glazed double skin facades in hot-arid climate areas with careful design, buildings' energy consumption can be reduced by greater than 10% compared to a single skin facade with high glazing area. Dynamic thermal analysis using IES-VE has been performed on a hypothetical office building in Riyadh city, Saudi Arabia, to simulate baseline and double skin scenarios to examine the performance of proposed variables. Variables include double skin facade typologies: Multi-story, corridor, and box-window, orientation of the facade, cavity depths: 100cm and 150cm, and ventilation type inside the cavity: natural and mechanical. Results showed that rooms adjacent to cavities in different scenarios have lower solar gain, lower cooling load, and improved surface temperature compared to the same rooms in baseline cases. Based on the findings, double skin facades that can reduce energy consumption provide improved thermal performance and help to increase comfort levels. All double skin facade scenarios showed improved performance comparing to the baseline cases. Box-window types show substantial improvement over all other scenarios. And scenarios with mechanically ventilated cavities provided the most improved results in terms of energy and thermal performance.
