Sunlight in Dwellings

Increasing urban densification results in limited daylight and sunlight availability. A study of current (2019) daylight considerations in architectural practices and an analysis of daylight recommendations in standards and sustainability certificates such as BR18, EN 17037, DGNB, BREEAM, LEED and WELL, revealed a neglectance of direct sunlight exposure, especially in living environments. Through qualitative analyses, including interviews and a picture survey across Northern countries, five sunlight criteria was defined as: Sunlight Hours, Winter Sun, Morning Sun, Golden Hours and Magic Moments. The criteria formed the basis for the new tool. The analysis tool was developed in a Rhino/Grasshopper/Ladybug/Honeybee environment and with the aim to be adapted in the design phase of architectural workflow or as an additional analysis tool for existing buildings.
