Sunlight Penetration through Sloped Window Apertures

Article Preview

Abstract:

Indoor illuminance levels vary frequently during the day due to the presence or absence of direct sunlight, cloudiness and content of atmosphere. In spaces equipped with roof windows these illumination effects of direct sunlight are more remarkable than in more common designed rooms with vertical windows. To study these effects the variable in form of orientation in relation to cardinal points, can be used and obtained different sizes of an area on a working plane directly illuminated by sunlight. This contribution presents a study of the impact and effects of direct sunlight, penetrated trough sloped window apertures on the working plane.
