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.

4.11 Integrated PV Shading

Shading devices are available that have photovoltaic (PV) materials which convert sunlight into electrical power. To maximize effectiveness of integrated PV shading, it should be facing south and as perpendicular to the sun's rays as possible. They may be used in any plane for shading but the power output will be compromised the farther away its placement is from perpendicular to the sun.
