REVIEW OF THE INNOVATIVE STRATEGIES TO IMPROVE DAYLIGHT PENETRATION IN BUILDING

Abstract

The innovative daylighting systems can deliver natural light to a space in a building, where insufficient amount of daylight is provided by the routine daylighting systems. The new building forms and users' needs cause in compacted buildings, and thus supporting the high skin-to-volume ratio not achieved. By using a survey of major applications for daylighting systems, this study provides practical advice to building designers and researchers. Many system have been lunched, but challenges, such as high initial cost, utilization difficulties, and application limitations, prevent their widespread use. Survey show that, none of them overcome all associated challenges, but a number of systems efficiently suit different circumstances is a more practical approach. The study makes the capabilities and limitations of the different system and discusses the challenges and promises facing architect and lighting designers.
