This study has conducted on developing an innovative approach for the parametric analysis of daylighting and visual comfort through a sun responsive shading system as well as proposed a parametric pattern of Iranian Traditional Girih Tile (ITGT). On this basis, using parametric methods, the authors could change the parameters of a pattern to build modern geometric patterns and a bridge between traditional architecture approaches and modern technologies. The model was simulated in the Rhinoceros 3D as well as the Grasshopper, Honeybee, and Ladybug plugins were performed in order to evaluate daylighting and visual comfort performance. The objectives are estimating the annual daylight metrics and glare discomfort during four months from spring to summer when 3 variables (opening and getting closed, mass to space ratio, and time hours) that affect incoming daylight and visual comfort performance in a room. The results showed that the proposed model could significantly improve the shading flexibility to control daylight metrics and glare, through a full potential adaptive pattern to achieve the maximum visual comfort.
