INVESTIGATION INTO ENERGY SAVINGS IN THE RENEWAL OF THE LIGHTING SYSTEM IN UNIVERSITY CAMPUS BUILDINGS

Abstract

This study shows the amount of energy savings to be achieved in electricity consumption if the current lighting system in the buildings of the Cumhuriyet University campus in Turkey is replaced with efficient lighting systems. In addition, environmental effects of energy savings are determined by calculating the amounts of CO2, SO2, NOx, CO emissions. The Life Cycle Cost (LCC) analysis is used to determine energy costs and payback periods. The calculations reveal that the use of three alternative lighting systems would lead to a substantial reduction in electricity consumption ranging between 16.5% and 40.5%, and that the payback periods of these alternative lighting systems vary between 1.9 and 5 years.
