Abstract
The wide spread of indoor public spaces which require an even distribution of lighting to provide pleasant environment, led to depending on daylighting as a main source of lighting in daytime. Daylighting these spaces through side lighting might be difficult and insufficient for that skylight is the best solution for introducing daylighting inside indoor public spaces. The thesis aims to identify skylight concepts and techniques that can be used in indoor public space of airport (holding rooms) in two different climatic zones: The hot arid climate with sunny clear sky of Cairo and the oceanic climate with cloudy sky of Berlin. The research concentrates on morphing skylight parameters and opening shape and integrating shading techniques such as horizontal louvers and vertical louvers.
This thesis consists of three parts and ends with conclusions and recommendations. The first part is chapter 1 and chapter 2 in which a theoretical study was conducted including the basics of daylight concept and daylighting systems. As well as the skylight systems and shading techniques. The second part is chapter 3 and chapter 4 in which an analytical study of indoor public spaces concepts especially in airports and its design requirements. It also includes an analytical study for different examples of utilizing skylight in indoor public spaces. Additionally daylighting metrics and simulation software were discussed. The third part is chapter 5 and chapter 6 in which the practical study was conducted for different design variants. The simulation conducted by 3D modelling software Grasshopper for rhino and the performance analysis conducted by Diva for Rhino.
The results were assessed based on four metrics; the IES approved method of Annual sunlight Exposure (ASE) and Spatial Daylight Autonomy (sDA ), the daylight availability and Daylight Glare Probability (DGP). Results present design guidelines for skylight in airport public space of holding rooms under the sunny clear sky of Cairo and cloudy sky of Berlin.
