Innovative Daylighting Systems for Efficient Daylight into Interor Architecture in order to Reduce Energy Consumption

One of the challenges of architectural design is to provide natural daylight into the internal spaces. Using proper daylight in building is desirable, not only for reason of energy saving, but for improvement of visual environment This performances can be through the use of daylighting systems. Daylighting systems are developed to provide daylight into the interior of buildings because daylight can only penetrate a limited depth through the window. Many of daylighting systems are available to the building industry but there are challenges in using limitations for reasons such as high initial cost, high maintenance of control systems and general utilization in buildings. The purpose of this paper is an overview of innovative daylighting systems with division into main principles, illustrating sketches, installation of systems and short descriptions of the elements. This category helps to select the right daylighting system for given building conditions.
