Proposal of a façade design approach for daylight performance determination in buildings

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.
