Educational buildings have the priority among other building types in daylight performance studies. There are several reasons for this. Classrooms which are used during the whole day should have sufficient and homogeneously distributed daylight. In insufficient daylight conditions, the use of electrical lighting increases energy consumption. Users� visual comfort should also be assured, and design incorporating natural light requires the analysis of sun protection devices in order to avoid glare and excessive heat. Also, atriums and skylights can be included in the building design with the aim of distributing light equally and in a relatively balanced manner throughout the building. However, lighting schemes are often proposed by architects and professionals who tend to make use of different design tools, and it would be pertinent to investigate whether these tools perform as desired. This study analyses daylight design principles and design elements in educational buildings. It outlines the method which has been used to analyse the daylight performance of buildings. A university building was selected for the field study. Measurements were taken in sample spaces to determine daylight performance. Utilising comparison between standard values and measured values, findings are presented in the form of tables, drawings and figures.

Keywords: Educational buildings; daylighting performance; design.

Do�al ayd�nlatma performans� �al��malar�nda �ncelikle incelenecek binalar aras�nda e�itim yap�lar� gelmektedir. Bunun �e�itli sebepleri vard�r. Derslikler, g�n boyu kullan�lan mek�nlar oldu�u i�in yeterli ve d�zg�n da��l�ml� do�al ayd�nlatma olmal�d�r. Do�al ��n yeterli olmad�� durumlarda yapma ayd�nlatma kullan�lmas� elektrik enerjisi t�ketimini artt�r�r. Ayn� zamanda, mek�n kullan�c�lar�n�n da g�rsel konforlar�n�n sa�lanmas� gerekir. G�n�� ile tasar�m, kama�maya ve a��r� miktarda do�rudan �s� kazan�m�na kar�� e�itli g�lgeleme elemanlar�n�n incelenmesini gerektirmektedir. Ayr�ca ��n e�it miktarda ve orant�l� olarak binan�n i�inde yay�labilmesi i�in de galeriler ve �at� ��kl�klar� tasarlanabilmektedir. Ancak mimarlar ve ilgili profesyoneller taraf�ndan �e�itli tasar�m ara�lar� ile �nerilen ayd�nlatma tasar�mlar�n�n, bina kullan�ma ge�tikten sonra istenildi�i ve �ng�r�ld�� gibi bir ayd�nlatma performans� g�sterip g�steremedi�i ara�t�rma konusu olmaktad�r. Bu �al��ma, genel hatlar�yla s�z konusu yap�lar i�in do�al ayd�nlatma tasar�m ilkeleri ve yayg�n olarak kullan�lan tasar�m elemanlar�n� incelemekte, mevcut yap�lar i�in ayd�nlatma performans� de�erlendirme y�nteminden bahsetmektedir. �nceleme alan� olarak bir �niversite binas� se�ilmi�tir. �rnek �al��ma ile bu binan�n do�al ayd�nlatma performans� de�erlendirilmektedir. Do�al ayd�nlatma performans�n� belirlemek i�in �rnek olarak se�ilen mekanlarda �l��mler yap�lm��t�r. �l��len de�erler ile standart de�erler kar��la�t�r�larak, elde edilen bulgular �izelgeler, �izimler ve �ekiller arac�l��yla sunulmu�tur.

Anahtar Kelimeler: E�itim yap�lar�; do�al ayd�nlatma performans�; tasar�m.
