Özet:

The aim of this study is the maximization of the occupant comfort with the minimization of the energy consumption for artificial lighting, heating and cooling in typical Turkish school buildings through the better design of the fenestrations which were predetermined with a directive called “Eğitim Yapıları Mimari Proje Hazırlanması Genel İlkeleri” i.e. the “General Principles For Preparing Architectural Projects For Educational Buildings” as a monotype regardless of orientation and climate. The study was conducted through the daylight and thermal analysis of a typical classroom diversified with alternative fenestration configurations for north and south orientations with a simulation software, namely “Ecotect Analysis 2011”. In addition, the simulated data were validated through the daylight analysis of the classrooms of a school building located in Çankaya District of Ankara with data loggers. The study provides information about the effects of the area, shape, location and orientation of windows as well as the effects of a lightshelf and an overhang on the daylight and thermal performance of these buildings. According to the study, the directive fails for both north and south orientations and visual comfort can be reached only for south facing classrooms with the use of a lightshelf, therefore, classrooms facing north should be avoided unless the classroom sizes are changed. The study also reveals that a more detailed analysis is required to optimize the fenestration of these building with respect to thermal and daylight performances and it is not appropriate to set a monotype window design for all orientations and climates.
