    Recently, indoor louver-type daylight redirection systems have been recognized as a passive solar technology for reducing lighting energy use in South Korea. However, their energy-saving performance is not quantitatively reflected in the current zero-energy building certification system. This study compares international lighting energy performance standards, including EN 15193-1 and DIN V 18599-4, thereby proposing a monthly lighting energy-saving assessment method for indoor louver-type daylight redirection systems based on EN 15193-1 Method 1. The system is represented as a light-guiding system, and its daylight contribution is reflected in the daylight supply and daylight-responsive lighting control factors. A case study of an elementary school classroom demonstrated that the proposed method can quantify the lighting energy-saving effect of the system on a monthly and annual basis. The results indicate the applicability of the proposed method for assessing building energy performance.
