This study highlights the importance of passive design strategies, specifically sun-shading devices, in
enhancing daylight performance and thermal comfort in tropical office buildings. The findings indicate that
introducing shading devices improved Spatial Daylight Autonomy (sDA) from 60% to 80%, exceeding the
LEED threshold of 55%, while reducing Annual Sunlight Exposure (ASE) from 48.5% to 4.6%, meeting
LEED’s criteria of under 10%. These results underscore the dual benefit of maximizing natural light while
minimizing glare and overheating, crucial for reducing energy consumption and improving occupant com-
fort in tropical climates.
