Abstract
The use of natural light is very beneficial in office buildings because energy consumption can be reduced, and working conditions can be enhanced, which positively affect workers’ health and productivity. this research show the problems of energy and illumination of deep-plan, the definition and benefits of Daylighting, Daylighting in design process, advanced Daylighting systems, and case studies for light transport systems. However, bringing natural light into deep-plan office buildings is not possible with simple windows or skylights, and advanced Daylighting transport systems are necessary to bring natural light into the deep cores of buildings. Advanced Daylighting transport systems usually need sun-tracking devices to collect natural light that are complicated, expensive and require continual maintenance. Mirrored light pipes coupled with laser cut panels are a passive and simpler daylight transport solution and are the focus of applied study in this research.
