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.

4.2 Building Orientation

Building orientation is important for any daylight design relying on sidelighting.

  • South-facing windows are generally considered the most desirable. Light is most abundant in this orientation but can vary throughout the day.
  • North exposure is typically considered the next most desirable orientation. Light is less plentiful but more uniform. Consider high performance glazing to reduce thermal losses during heating conditions.
  • East and west facing windows are generally avoided. They can generate large solar gains and frequently require complex shading systems that can block vision glazing.
