Global warming is becoming a serious concern day by day. Indonesia still uses a large portion of fossil fuels in electricity generation, has made matters even worse due to carbon emissions. Government through PP No. 70 of 2009 issued an energy conservation policy stating that energy use must be carried out economically and efficiently. The objective of this policy for all sectors of life, not to mention the academic environment. Library spend a lot of energy consumption for support that activites especially in the lighting system. Observations and measurements were performed to see the illuminance of the library because when seen visually very bright. The results are then compared with the standard, whether it meets the minimum threshold or not or even exceed, and how the savings opportunities that can be done. The method that used in this research is data collection, measurement of illuminance, and search for savings opportunities through simulations. Based on methods, a savings opportunity is obtained by reducing the number of lamps used. If this step is applied then obtained savings of up to 514 kWh/year, equivalent to the electricity bill amounting to IDR 462.672.000, - from the lighting system.
