摘要
Insufficient daylighting can negatively affect working quality and productivity and increase lighting energy consumption in buildings. Particularly, the western orientation has a non-uniform daylighting distribution, especially at the zone next to the window resulting from the unequal radiation distribution of sunlight. Therefore, this study presents an innovative system known as Integrated Kinetic Fins (IKF), which can respond parametrically to the sun's movement; to enhance the daylighting distribution during the late working hours for the western facades and decrease the high illuminance daylighting spots near the windows. The study optimizes the fin parameters based on a selected territory; then, the fi angles are automatically controlled. The IKF is applicable in regions with clear skies and low solar altitudes. Finally, a comparison between a traditional kinetic system and the IKF is made, and the results are reported. The system shows an enhancement of daylight distribution during these late hours, where the contrast has been improved by 22% and uniformity has been enhanced by 10%, which consequently contributes to reducing potential glare.
