Optimization of lighting design in classroom for visual comfort (Case Study : Universitas Tridinanti Palembang Tower)

Abstract

Currently, the learning process in the classroom uses an LCD projector to display material on the white board. This LCD projector produces its own light, so the light source in the room will be added (beside daylight and artificial light). This condition makes a visual discomfort and not efficient energy uses. Based on previous study, the classroom users in UTP tower got visual comfort when the lamps were on 100% if projector used. But, in other condition when the projector is off, users will comfort if daylight and electric lighting combined. Based on these problems, this study is aimed to test the effective combination of daylight and artificial lighting so that the iso-contour of illumination spread evenly and visual comfort achieved. The method of experiment is used to find out the effect of various placements of artificial light that are on to the iso-contour of illumination. The experiments conducted with the help of simulation to experiment with design parameter is the placements of artificial light that turn on. The evaluation of visual comfort is based on the iso-contour of illumination and reflectance value on the indoor surface. The result of this research will show that the placements of light on will affect the illumination contour.
