Evaluation of SBI and SBI-Airmass as Indicators for Sunlight Access
The assessment of sunlight access in buildings is constrained by methods that rely on simplified point-based evaluation. EN 17037 sunlight exposure evaluates sunlight at a single point on the aperture under restricted temporal conditions. This limits the representation of how sunlight interacts with the aperture over time. These characteristics reduce its applicability at early design stages. The
