Abstract
One of the challenges of architectural design is to bring daylight into the core of a building in an effort to improve visual environment and, at the same time, to increase energy savings. This can be performed through the use of daylighting systems, the operational principles of which are presented in this chapter. Using sunlight/skylight redirection or exclusion these systems can affect a building’s energy behaviour since their adoption is subject to a compromise between shading needs and daylight provision. The choice of the proper daylighting system should be based on a ‘solid’ rating system, which is quite difficult to develop since a large number of parameters are involved. These include the site, climate, openings, operational and integration constraints, and the objectives that the design team has initially set. Although a large number of daylighting systems are available to the building industry today, their use is limited for reasons such as high initial cost, maintenance and variability in their performance parameters.
