ABSTRACT
Library with good environment will create comfort, calmness, and satisfaction for users while doing the activities. One of the aspect to consider in creating a good library environment is lighting. Lighting needs can be met from daylighting and artificial lighting. Artificial lighting had advantage in terms of relatively constant light intensity in the range of work hours, but this approach requires electric operating costs. This research analyzes the current lighting conditions in SebelasMaret university library that influenced by daylighting and artificial lighting. The analysis process will be using software surfer V.10 based on the value of the intensity of light at each measuring point. The result indicated that the average of light intensity is still below the prescribed standard so that redesign needs to be done. In the redesign process will focusing on the artificial lighting that calculated using lumen method with two different conditions.
