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.

3.3 SkyCalc®

From the h-m-g.com web site:

SkyCalc 2.0 ® operates at three levels of detail:

  • The first level requires little information from the user, instead relying on extensive defaults to describe the user's skylighting system and building operation.
  • The second level allows the user to modify any default in order to describe the situation more precisely.
  • The third level allows the user to enter detailed information about products and schedules such as performance data for specific products or detailed building operation information.

SkyCalc® is a Microsoft Excel-based program with screens similar to what is shown here and can be downloaded for free at http://www.h-m-g.com/downloads.htm.
