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.

1.2 Benefits Of Daylightings?

How is daylighting going to improve a building and its occupants?

Through various daylight harvesting techniques, combined with high efficiency lighting fixtures and controls, building owners can significantly reduce energy costs. Many construction projects are in climates where there is a significant level of daylight available and where the temperature differential between inside and outside is at a minimum for a significant portion of the year.

Improved Interior Environment

The correct placement of both daylighting and view glazing can make an interior space more pleasing. In fact, recent studies have shown a positive correlation between daylight and both academic performance and retail sales. See http://www.h-m-g.com/projects/daylighting/projects-PIER.htm. Likewise, daylit spaces may lease at better-than-average rates and experience lower tenant turnover.

Improved Health

Recent research is indicating there is a strong relationship between light and human health. Our circadian rhythms benefit from daylighting.
