ABSTRACT
Daylight is an integral to building design, historically playing a crucial role in shaping many architectural masterpieces. The importance of daylight design in architecture is underscored by early sketches of iconic structures such as Alvar Aalto’s Viipuri Library and Le Corbusier’s study of the horizontal window in his Five Points of Modern Architecture.
However, a noticeable absence exists in physically accurate daylight sketching methods that can effectively depict how design decisions affect the final daylight quality. This gap is addressed by proposing a robust, simple, and physically accurate method for sketching daylight inside the aperture, while considering obstructions in the aperture field of view.
By offering a method that allows for a physically accurate representation of daylight under overcast conditions, the author aims to promote a deeper understanding and engagement with daylight design within the architectural community, as well as to equip architects with the sketching tools needed to visualize and optimize daylight from an early stage.
