The conditions of Ottoman architecture persisted during the republican period at the turn of the 20th century. Later, radical changes in the structure of the state affected the field of architecture, and changes in the world were reflected in our country. The structures that are the subject of architectural debates are typically early republican period buildings, which were built between 1920s and 1950s. On the other hand, in past buildings, the interior design criteria that are important for the user in interior design have been the subject of interest in various disciplines. Lighting – daylighting and electric lighting – in different interiors is one of the design criteria that has intrigued many researchers. Laboratories, classrooms, studios, circulation areas, administrative spaces, offices, conference rooms, and wet spaces are all common features of educational buildings. Each of these spaces has unique lighting requirements. The aim of this study is to assess the daylighting performance in the interior and encourage similar studies in historical educational buildings rather than the architectural design of these buildings. Daylighting performance was assessed in the analytical chemistry laboratory at the Ankara University Faculty of Science, block A, which was built during the Second National Architectural Movement and bears the traces of Sedad Hakki Eldem, Emin Onat, and Paul Bonatz. A morning interval (10:00–11:00) where the courses are considered the most productive was chosen for the evaluation. The results were compared and interpreted with the values specified in the standards; the measurement is limited to the day and time interval.
