Optimal tubular daylighting configuration limits overlit areas to 20.7%, enhancing visual comfort.
The 4×350 mm configuration achieves the highest global score of 66.5% with low annual sunlight exposure.
Analysis through parametric simulation evaluates multiple configurations for balance in daylight performance.
Findings underscore importance of daylight quality metrics, aligning with EN 17037 and LEED v4 guidelines.
