Optimal energy use is increasingly vital in architecture, where building envelopes significantly impact aesthetics, thermal comfort, daylighting, and energy use. This study examines various traditional Girih tile patterns in Isfahan’s building openings, focusing on their wood-to-glass ratios and effects on useful daylight, visual comfort, and thermal comfort. Using software simulations in Rhino7, Honeybee, Ladybug, MATLAB, and SPSS, the research identifies Pattern 6 as the most effective. While all patterns were beneficial, some achieved over 97% visual comfort by reducing glare, especially on western and eastern façades, and those allowing over 20% daylight above 3000 lux suited precision-focused spaces.
