The Saudi Al-Jubail project is a business facility of APOC (Advanced Petrochemical Company), a state-owned petrochemical company in Saudi Arabia. The continuous growth and development of 'APOC' was embodied in 'Infinite Loop', showing symbolic formative beauty. The form went beyond the simple appearance and was proposed as a space for exchange and communication where internal and external programs are organically connected and expanded. Through a thorough simulation review, it was planned to be an eco-friendly building with high efficiency and a clean energy complex.
