is a daylighting strategy that uses apertures located in the wall planes as the point of admission for ambient daylight.
is a daylighting strategy that uses apertures located at the roof plane as the point of admission for ambient daylight.
3 ways to improve the amount of light available from a window.
Are used to more evenly distribute daylight entering a building through sidelighting apertures
12” minimum width
An effective way to enhance the lighting from windows on the equator-facing side of a structure.
The light shelf projects beyond the shadow created by the eave and reflects sunlight upward to illuminate the ceiling.
is any horizontal window, roof lantern or oculus, placed at the roof of the building, often used for daylighting.

A devices consisting of a lens that is
installed on the roof, an adjustable mirror-lined tube (10- 20” diameter)
It is placed into a roof and admits light to a focused area of the interior.
Maximize ceiling and window height to gain better light distribution
Separate Daylighting and View Windows.
Bring Daylight in from above to obtain deeper penetration into space.
A southern facing orientation is optimal if a building or system is located in the northern hemisphere, and a northern facing orientation is optimal if located in the southern hemisphere.
Too much glass could end up with heat-gain and heat-loss problems, and glare issues.
Filter and shade daylight to avoid direct sun and sky light
Bounce daylight off surrounding surfaces to diffuse light in more even patterns
