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.

The sidebar image shows a skylight design being developed by the Skylight Efficacy Project to improve daylighting in a portable classroom and the Customer Technology Application Center (CTAC) classroom. The new diffuser design decreases glare and increases ceiling brightness to make natural lighting more appropriate to a learning or office environment.
