Lighting design refers to the various techniques and strategies for using light for practical purposes or theatrical effects within a space. Utilizing a variety of lighting sources from artificial sources such as light fixtures, pendants, floor lamps, and table lamps to natural daylight through windows and skylights, quality lighting is essential in creating and enhancing the functions of spaces. Because lighting is often a major source of energy consumption within buildings, lighting design today typically incorporates new technologies, daylighting controls, maintenance systems, and better space planning to reduce the energy needed to light a space. The following guides and resources have been brought together to better illustrate the range of techniques and fixtures associated with lighting design.
