| Abstract |
Daylighting plays a key role in improving building energy efficiency, supporting occupant well-being, and providing visual comfort. As
research and technology advance, green building certification systems have increasingly adopted performance-based approaches to daylight
assessment. This study compares the evolution of daylight evaluation criteria in G-SEED and LEED using a framework that considers
building classification, evaluation methods, performance metrics, assessment conditions, and scoring structures. Official manuals and technical
guidelines from multiple versions were analyzed to identify major changes and trends. G-SEED has traditionally relied on static metrics such
as the Daylight Factor (DF), but the recently announced 2025 draft revision represents a major shift. The revision integrates daylighting into
a broader visual comfort category and expands its application to all building types. In contrast, LEED has evolved from Daylight
Factor?based assessments to dynamic simulation metrics, including Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE),
with ongoing refinement of scope and point allocation. These findings highlight the need for G-SEED to adopt more rigorous,
performance-based frameworks aligned with global best practices to improve environmental performance and support occupant-centered design. |
