Estidama Mosque in Masdar Park, Abu Dhabi, is a landmark in sustainable religious architecture, achieving LEED Platinum certification and meeting Estidama (Pearl) standards. Its passive design strategies, including skylights, mashrabiya screens, vaulted ceilings, and optimized daylighting, reduce energy demand and create a serene, climate-responsive interior. The mosque delivers substantial environmental performance: roughly 50-60 % water savings, over 50 % reduced energy consumption, and a 40 % cooling demand reduction over traditional mosque typologies. ​ The design bridges cultural expression and environmental stewardship, blending Islamic geometric patterns with modern sustainable techniques. It’s not just a place of worship—it’s a symbolic community gathering space that embodies Masdar’s vision for a greener, spiritually resonant urban environment.
