Investigation of Lighting Performance and Improvement of Efficiency in a Designated Area of an Active Educational Building

Due to the inefficient use of daylight in many areas, the demand for artificial light sources, which have a history of approximately 200 years, has increased. This increase has particularly highlighted the need to investigate the energy quality, savings and efficiency of lighting systems in modern times. In this study, the lighting devices used in a selected classroom within the Central Classroom building at Hakkari University's Zeynelbey campus were examined. Photometric measurements were conducted under different seasonal conditions (winter and summer) in this area, including scenarios with natural, artificial and combined lighting. The obtained results were compared and evaluated against current standards. Additionally, the measured classroom was modeled using the DIALux lighting design software and a more efficient and economical lighting model was proposed using lighting devices with different power and characteristics for these areas. Based on the findings of this study, recommendations were made for selecting appropriate lighting systems and determining the usage patterns of lighting devices to improve working conditions and further reduce energy consumption with the existing lighting devices.
