Maximizing the Performance of Laser Cut Panel by Interaction of Ceiling Geometries and Different Aspect Ratio

Abstract

The interaction between different ceiling geometries with laser cut panels (LCPs) is investigated using real experiments and computer simulations to maximize the daylight performance of the LCP. In addition, LCP with different aspect ratios (width to depth ratio) is studied using simulation with clear sky conditions in hot climate region. Two main performance parameters are investigated: illuminance level and distribution uniformity in a large space located in a sub-tropical climate region like Jordan. It was found that curved and chamfered ceilings increased the daylight level in the rear part of the studied room by 20% compared to a horizontal flat ceiling and reduce it by 30% in front part that improve the quality of daylight by improving the uniformity. LCP with high aspect ratio of 5:6 performed well in climate with clear sky and high solar angles than LCP with ratio of 4:6. © 2014 The Author(s). Published by solarlits.com.
