Natural Lighting System to Provide Visual Comfort in Library Reading Room at Universitas Budi Luhur, Jakarta

Abstract

The general purpose of natural lighting is to produce quality of light that is efficient and minimizes direct glare, and excess light level ratios. The natural light that enters through a window can come from several sources, namely direct sunlight, clear sky, clouds or reflections of the lower surface and surrounding buildings. The light from each source varies not only from the amount and heat it carries, but also on other qualities, such as colour, spread, and savings. Light is the most important part of human life, to get the right lighting in a space, the right lighting system is needed according to people needs so that visual comfort can be achieved. The library is an important means to support teaching and learning activities and in supporting the implementation of the Three Principles of Higher Education and, the library should be the centre of attention, especially in its lighting system. This study applies a quantitative analysis method with a descriptive approach where the measurement of natural lighting levels and calculation of the dimensions of shading devices are carried out as part of the research stage. The independent variables in this study are the use of shading devices, while the dependent variables observed are natural lighting levels and natural lighting factors. The results of this study are natural lighting systems in the form of design solutions that allow it to apply in the 3rd-floor library reading room at Budi Luhur University.
