Abu Dhabi [UAE], January 9 (ANI/WAM): Abu Dhabi City Municipality emphasised that the Estidama Pearl Rating System is a tiered evaluation system, ranging from one to five pearls. It assesses buildings based on their adherence to sustainability requirements. Government-funded projects must achieve a minimum two-pearl rating, while privately funded projects must achieve at least a one-pearl rating. Meeting these requirements is essential for obtaining a building permit.
