ClerestoriesProvide high quality and high quantity illumination over large area. Slide3
Not workable in multistory buildings
Doesn’t satisfy view and orientation Top lighting should supplement and not replace windows. Slide4
Skylight
Horizontal or slightly sloped openings in the roof.Direct sunlight needs to be diffused for better visual performance and reducing glare.
Skylight face the summer sun more than winter and collect more heat in summer problemGlare and heat Slide5Slide6
Skylight Strategies
1- Skylight Spacing Slide7
2- Use splayed openings
for better light distribution.
3- Place the skylight high in a space.For light to diffuse and reduce glareSlide8
4. Place skylights near
walls
5. Use interior reflectors to diffuse the sunlight.Slide9Slide10Slide11
6
. Use exterior shades and reflectors
.7. Use steeply sloped skylights to improve the summer/winter balance.Slide12
8.
Use sunlight for dramatic effect.Slide13Slide14
Clerestories
Monitors
when the window face two sidesLight Scoops the window face one direction and reflect light with the opposite side Slide15Slide16Slide17Slide18
Vertical clerestories has the characteristics of windows rather than skylights
Facing south: collect more sunlight in winter than in summer, can be shaded easilyFacing north: low but constant light with no glare
West and east are to be avoided ;receive more summer sun than winter and hard to shadeSlide19
Advantage of clerestories
diffued light; the result from light reflected off the ceiling
Disadvantage no view Slide20
Clerestory strategies
1- Orientation.Facing south: collect more sunlight in winter than in summer, can be shaded easilyFacing north: low but constant light with no glare
West and east are to be avoided ;receive more summer sun than winter and hard to shadeSlide21

White reflective roofs to collect more sunlight Slide23
