Enhancing Lighting Efficiency in Deep Plan Classroom: Artificial and Daylighting

İngilizce (OpenAlex)

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.
