Natural lighting optimization through configuration of shading device for library in East Jakarta

Abstract

Visual comfort is an important thing to consider in designing a library. The quality of lighting in reading rooms in public libraries in Jakarta is still below the SNI lighting standard of 300 lux. This study will discuss about optimizing and utilizing natural lighting for the reading room by using a combination of several types of shading devices. The method used is performing simulations and comparisons. A total of 138 types of shading devices were simulated with the VELUX Daylight Visualizer software and compared to find the best results. The results of the comparative analysis show that the GH1-19 shading device provides the most optimal results with an average illumination level of 548 lux and a uniformity ratio of 0.81 simulated in different seasons, times, and orientations.
