Basics of Daylighting in a Green Environment
The use of natural sunlight, known as daylighting, to illuminate a building can save energy, reduce operating costs, create visual appeal, and enhance occupant health and productivity. The U.S. Green Building Council Leadership in Energy and Environmental Design (LEED™) rating system encourages the use of daylighting to achieve high performance buildings. This course provides an introduction to the use of daylighting in commercial spaces. The course objective is to show why daylighting should be considered, the basic guidelines of using daylighting and some words of caution when using certain daylighting techniques.

3.1 Skylights

For single story buildings and for the top floor of multi-story buildings, skylights are frequently a good technique for admitting daylight.

  • For single story buildings and for the top floor of multi-story buildings, skylights are frequently a good technique for admitting daylight.
  • Skylights are, to varying degrees, effective all day long providing consistency while still offering interest.
  • Skylights operate fairly independent of the sky condition.

The opening of the skylight will typically be made of diffusing or prismatic elements to distribute direct solar contributions. Where costs allow, skylights are also available with internal louvers that offer additional flexibility to the occupants.

In general, the more shallow the well of the skylights, the more uniform the lighting will be in the space.
