Electric power saving optimization simulation for the comfort of classroom lighting

Abstract

Classroom lighting is one of the essential factors in learning process for students in a university. There are two types of lighting available to apply inside a classroom, i.e., natural and artificial lightings. This research aims to simulate classroom lighting management technology concerning Indonesia National Standard SNI 6197:2001 using Dialux software. The simulation result shows that the applied artificial lighting inside E11-210 room had not followed the standard yet, in 350 lux. The existence of both artificial and natural lightings has made E11-210 room were excessive in light intensity, despite successfully obeying the standard. This paper uses lamp power modification to optimize the light intensity efficiently without to infringe the standard. This paper also presents the potential benefit of implementing power modification in saving electricity usage costs for 56.94%.
