Enhancing Lighting Efficiency in Deep Plan Classroom: Artificial and Daylighting

Öz

Insufficient light distribution throughout the classroom has a negative impact on students. Therefore, it is crucial to implement effective daylighting and artificial lighting strategies in educational buildings. To address this issue, a combination of a horizontal daylight tubes and an overhang was proposed for a classroom at the selected university. The aim was to enhance the availability of daylight and reduce glare. The goal is to achieve a Spatial Daylight Autonomy (sDA) of at least 55% and an Annual Sunlight Exposure (ASE) of no more than 10% in the designated analysis area, as stipulated by the daylight assessment criteria outlined in LEEDv4 standards. In addition to the improvements in the daylight performance of the classroom, an artificial lighting system was proposed to replace the existing system, which creates homogeneous and sufficient lighting. Reducing the energy consumption of the proposed system is also among the desired targets while evaluating the proposed systems, Rhinoceros and ClimateStudio were used for daylight simulations and DIALux was used for artificial lighting simulations. The results show that proposed solutions were successful as intended. Moreover, with the proposed artificial lighting system, the lighting values required by the standards have been achieved and energy consumption has been reduced.

Derin Planlı Sınıfın Aydınlatma Verimliliğini Artırma: Yapay Aydınlatma ve Gün Işığı

Öz

Sınıf genelinde yetersiz ışık dağılımı öğrenciler üzerinde olumsuz bir etkiye sahiptir. Bu nedenle, eğitim binalarında etkili gün ışığı ve yapay aydınlatma stratejilerinin uygulanması son derece kritiktir. Bu sorunu ele almak için, seçilen üniversitedeki bir sınıf için yatay bir gün ışığı tüpü ve bir çıkma kombinasyonu önerilmiştir. Amaç, gün ışığının kullanılabilirliğini artırmak ve parlamayı azaltmak olarak belirlenmiştir. Hedef, LEEDv4 standartlarında belirtilen gün ışığı değerlendirme kriterlerinde öngörüldüğü gibi, belirlenen analiz alanında en az %55'lik bir Mekansal Gün Işığı Otonomisi ve %10'dan fazla olmayan bir Yıllık Güneş Işığı Maruziyeti elde etmektir. Sınıfın gün ışığı performansındaki iyileştirmelere ek olarak, mevcut sistemin yerine homojen ve yeterli aydınlatma sağlayan bir yapay aydınlatma sistemi önerilmiştir. Önerilen sistemin enerji tüketiminin azaltılması da istenen hedefler arasındadır. Önerilen sistemler değerlendirilirken gün ışığı simülasyonları için Rhinoceros ve ClimateStudio, yapay aydınlatma simülasyonları için ise DIALux kullanılmıştır. Sonuçlar, önerilen çözümlerin amaçlandığı gibi başarılı olduğunu göstermektedir. Ayrıca önerilen yapay aydınlatma sistemi ile standartların gerektirdiği aydınlatma değerlerine ulaşılmış ve enerji tüketimi azaltılmıştır.
