Reparametrize Ateliers unveils a groundbreaking facade design for the Al Jalaa Hotel, showcasing a harmonious blend of sustainability, performance, and artistry. The building skin seamlessly integrates low-E glass and Glass Fiber Reinforced Concrete (GFRC), achieving a lightweight yet robust enclosure. This strategic material selection minimizes heat transfer for optimal energy efficiency while enabling the intricate geometric detailing inspired by the Umayyad Mosque's ornamental features, a testament to GFRC's versatility. Further emphasizing this commitment to sustainable design, the entrance canopy features a powerful combination of Ultra High Performance Concrete (UHPC) for structural integrity and Ethylene Tetrafluoroethylene (ETFE) panels for a luminous, naturally lit welcome. Beyond material innovation, the facade's underlying diagrid framework, inspired by natural structural efficiencies, optimizes load distribution for minimal material usage and maximum strength, culminating in a visually striking, open aesthetic. The Al Jalaa Hotel's skin sets a new precedent for architectural design, demonstrating how cutting-edge materials and biomimetic principles can converge to create a truly iconic and environmentally responsible structure.
