Indoor Lighting Conversion Approach for Sustainable Energy Efficiency Applications in Campus Buildings: Hitit University Engineering Faculty Study

Global energy crises, limited energy resources and damage to nature in energy production have pushed humanity to use energy more efficiently and renewable energy sources. In this context, the importance of implementing energy efficiency and sustainable strategies in buildings which consumes high energy, has increased. In this study, the effect of luminaires substition with more efficient ones and electricity production by renewable energy sources on efficiency, sustainability and environment was examined on a sample education building.The calculations were made according to standards and equipment supplier data. As a result of this study, it has been found that the use of high-efficiency LED lighting instead of halogen or fluorescence luminaires in the engineering faculty building and laboratory of Hitit University, will reduce the electricity consumption by 68.2%. In addition, it has been deduced that the solar energy system to be installed on the faculty’s roof, will significantly reduce CO2 emission, and has a payback period of 5.5 years. In terms of gas emissions, a roof-mounted solar energy system is 21, 45, and 32 times less hazardous to the environment than natural gas, lignite, and fuel oil, respectively.
