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.

3.5 Tubular Skylights

Where a space has a deep ceiling or for retrofits, a tubular skylight may be the answer. They are smaller in scope, intending to illuminate about 75 to 150 square feet per tube. This makes them ideal for private offices and other smaller spaces. This product typically consists of a collector at the top and a diffuser at the bottom.


Tubular skylights are most likely to be used in:

  • The bottom floor of a multi-story building
  • A warehouse
  • In applications to reduce heat loss in winter or solar gain in summer
  • A private office
