Sawtooth roof system in improving daylighting performance in aerial sports hall

Abstract

Daylight is the most commonly used type of lighting, and people always welcome it. Even though people have sought to avoid direct sunlight, daylight is always appreciated in public spaces. The importance of natural daylighting for energy efficiency in building has been acknowledged. Additionally, natural daylighting is good for users' psychological and physical health, particularly in terms of their mood, performance, and productivity. Black box architecture typically depends heavily on artificial lighting to fill the room with enough brightness because these spaces lack natural sunshine. The lighting in an aerial sports venue must be carefully considered since both excessive and inadequate illumination might have negative effects. Both circumstances had an impact on the participants' eyesight, which in turn influenced how well they played the game. In an aerial sports hall, natural lighting is advised to save energy use and improve player performance. The athlete's relationship to the light, the activity, and the space is crucial, and ideal sporting circumstances depend on proper spatial geometry and enough illumination. A top-lighting system is a daylighting technique that uses roof openings to evenly distribute daylight across the top floor design. Sawtooth roofs are used in various skylight strategies because they provide gentle, diffuse light rather than harsh light, which is why they are used in aerial sports halls. In this study, several settings and configurations are being tested to determine the best layout for the selected sports hall. Results from the VELUX Daylight Visualizer are assessed and discussed in order to get a reading of the Daylight Factor (DF) and illuminance value (lux), which will help researchers establish whether they are appropriate for the design.
