Top Daylighting

Skylights and clerestories are a source of top daylighting which admit additional daylight and solar energy inside a building. Even on cloudy days, top lighting can provide excellent daylight because it has more of a view of the upper sky vault. Top daylighting should be complemented with side daylighting, light shelves, and high-reflectance surfaces to provide uniform deep-plan daylighting without the glare of direct sunlight.
