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.

1.1 Sustainable Lighting

Over half of the energy used in a commercial building can be for lighting. However through proper lighting design and the use of energy efficient lighting technologies, the energy required for lighting can be significantly reduced and the overall quality of lighting enhanced.

An essential element of good lighting design is the use of natural lights, or daylight.

The purpose of this module is to provide some basic guidelines for considering daylighting in a space. While daylighting offers many health, energy and environmental benefits, it should always be part of a broader energy efficient lighting plan including lamp selection,
luminaire selection and the use of lighting controls. For additional information in these areas, see references below.
