The impact of daylighting-guiding systems on indoor natural light penetration: Simulation analysis for light-shelves

Abstract

Daylighting-guiding systems and control strategies are considered as an important step in providing daylit indoor spaces as well as energy-efficient building environments. The application of daylighting-guiding systems is only one significant constituent of a daylighting strategy. These systems could be categorized by many characteristics; therefore the designer must be aware when choosing a system according to the circumstances of the space. However, a poor selection of systems could spoil the performance of a building with good daylight potential. This research paper concentrates on the role and properties of daylighting systems especially the sidelighting-guiding ones, taking into consideration their influence on daylighting performance within indoor spaces. It is also corroborated by a simulation analysis on one type of daylighting-guiding systems: Light shelf through studying its impact and influence on natural light penetration.
