Daylighting is a key component for incorporating visual comfort conditions and reducing energy consumption in buildings. In order to assess daylight potential in the building design phase, diverse performance metrics are developed and are being used in building design phase. These metrics are also integrated into several dynamic lighting simulation algorithms so architects, lighting designers or façade consultants can practically determine the daylight performance of designated façade alternatives in terms of daylight availability, compare design variants and perform necessary revisions during the building design phase. This study deals with proposal of a façade design process in terms of daylight performance determination and aims to describe current daylight metrics that can be used for façade design and applications. Proposed process consists of determination stages based on daylight illuminance, control of glare and view out conditions. With the implementation of this process to façade design, it is possible to provide visual comfort conditions and minimise lighting energy efficiency in buildings.

Lighting retrofit in retail environments is essential and is often necessitated in order to improve the retail atmosphere, increase energy efficiency and provide visual comfort conditions. This study introduces the lighting design criteria for retail environments in terms of visual comfort conditions and lighting energy efficiency and investigates a retail lighting retrofit application on the example of a department store. Several lighting system design alternatives including diverse lighting technologies are assessed in terms of visual comfort conditions and lighting energy efficiency. Obtained results emphasize that without compromising visual comfort conditions in retail environments, it is possible to obtain significant lighting energy consumption on an annual basis. This study clearly underlines the importance of a proper lighting retrofit project in terms of providing visual comfort conditions and lighting energy efficiency.

S Office environments can be integrated with particular workspace configurations owing to diverse tasks encountered in these workspaces. This study attempts to discern how effective different office workstation configurations are on daylight performance and tries to quantify this effect by means of a dynamic daylight simulation based approach, depending on the criteria addressed in EN 17037:2018 Standard. The purpose of this study is to explore the impact of workstation configurations on daylight provision and glare protection in workspaces through several configuration setups. In this study, climate based daylight metrics are used for daylight performance determination and assessment of discomfort glare caused by daylighting is performed by Daylight Glare Probability (DGP) index. This study aims to contribute to the growing body of research in the scope of EN 17037:2018 for daylighting in office environments and the obtained results represent the significance of daylighting and visual comfort conditions for diverse workstation configurations.
