With the full implementation of the Zero Energy Building (ZEB) certification system in 2025, the importance of introducing and enhancing the performance of passive design elements has increased significantly. The indoor louver-type concentrating daylighting system is considered an important passive design strategy that can improve the quality of the indoor lighting environment, while simultaneously reducing lighting energy consumption. This study aims to analyze the effects of different reflective types of indoor louver-type concentrating daylighting systems—diffuse reflective and specular reflective—on the indoor lighting environment. Indoor illuminance, uniformity ratio, and daylight factor were adopted as evaluation metrics. The results show that, compared to the specular reflective type, the diffuse reflective type improved indoor illuminance by approximately 39% and uniformity ratio by around 18%. In addition, the daylight factor increased by up to 56%. These results confirm that the reflective characteristics of indoor louver-type concentrating daylighting systems have a significant influence on daylight collection performance and the formation of the indoor lighting environment.
