Visual integration of the building interior and exterior is one of the charms of today's architecture. The Double-Skin facade system is a technology that can reduce the drawbacks of using glass in a building's elevation. In fact, the double-skin façade (DSF) offers transparency while reducing energy consumption when compared to single-skin systems in cold and moderate weather conditions. However, there is no clear evidence of how the system will perform in hot climate conditions. In this research, a testing procedure was established to experimentally evaluate the performance of the double-skin façade system, data was collected to create multiple regression models, and then evaluate the double-skin façade's performance and compare it to a single-skin system in hot arid climate conditions. / Doctor of Philosophy / Improving the quality of indoor environments is a main goal in today’s architecture. Towards this goal, the use of glass and curtain walls is common in office buildings. The building façade is a key factor for the amount of energy consumed to reach comfort levels in the building. That is, because facades influence lighting, glare, heat gain, noise safety and energy usage. Therefore, the use of glass improves transparency which can interfere with comfort levels inside the building due to solar heat gain. The Double Skin façade system is widely adopted in Europe and has been shown to reduce energy used for heating in cold weather. In winter, heat losses can be reduced as the system’s intermediate cavity acts as a thermal buffer. However, there is no clear understanding of how the system will perform in hot arid climate conditions where cooling is the dominant operating mode. A Double Skin Façade can provide shading during the overheating period, while having the desired glass elevations sought by designers. This is due to ventilation and solar control devices located inside the system’s cavity. Being placed between the interior and the exterior glass panels, solar control devices are protected from the weather, which in return decreases its size. Furthermore, the additional glass panel allows windows in the system’s inner layer to be opened for natural ventilation. Unfortunately, the performance of the Double Skin Façade system for hot arid climate is not well documented. Therefore, the primary goal of this research is to compare the thermal and light performance of the Double Skin Façade system to a single façade system for hot weather conditions.

The subject of the diploma thesis is a project documentation of a multifunctional building within the scope of the implementing documentation. The main goal of the thesis is the design of the layout, construction and material solution, completed by design of the fire safety solutions and assessment in terms of building physics. The multifunctional building has one underground floor and nine above-ground floors. In the basement there are technical facilities of the building and a parking area, in the 1st floor there are business premises, in one part of the 2nd floor there is a gym and the remaining areas are used for administrative purposes as well as the entire 3rd to 9th floor. The construction system is designed as a reinforced concrete monolithic skeleton, completed by a reinforced concrete core. Ceiling structures are monolithic reinforced concrete locally supported slabs. The building is founded on the concrete slab placed on drilled shafts. The main element of the outer wall is curtain walling, which is made from a mullion-transom system.
