Al Rayan Mosque in Hatta, built by Dubai Electricity and Water Authority (DEWA), stands as a global model for sustainable, eco-friendly buildings. The mosque supports the strategic vision of the United Arab Emirates and Dubai in promoting urban sustainability, reflecting DEWA’s leadership in sustainable building design and its commitment to advancing national and global climate ambitions to achieve net zero by 2050.
Al Rayan Mosque in Hatta has been awarded the LEED Zero Carbon certification by the U.S. Green Building Council, making it the first place of worship in the world to receive this prestigious international recognition. The mosque achieved this milestone by offsetting 175% of its annual carbon emissions.
The mosque has also attained several other milestones in Leadership in Energy and Environmental Design (LEED). In 2021, it received the Platinum LEED BD+C v4 certification (Building Design and Construction, version 4) with a total of 83 points, becoming the first mosque in the world to earn this top-tier rating. In 2024, the mosque earned the LEED Zero Energy certification, once again making it the first house of worship worldwide to achieve this distinction.
The mosque generates more than 150% of its annual energy needs through high-efficiency photovoltaic solar panels, with excess power fed back into the grid. The solar energy system capacity reaches 158 kW, managed via a cloud-based control system.
The building has been designed according to the highest international standards, ensuring airtight construction that prevents air, water, or heat leakage. Its high-performance thermal glass in the roof and façades helps maintain cooling efficiency, reduce carbon emissions, and preserve the environment. Natural lighting is maximized to reduce energy consumption, while roof and building materials were selected based on solar reflectance values to minimize the urban heat island effect. Additionally, all water heaters operate on solar energy.
The mosque accommodates more than 600 worshippers and covers an area of 1,050 square meters, built to the highest environmental sustainability standards. It features a 25-meter-high minaret, parking spaces for cars and motorcycles, facilities for People of Determination, and a Green Charger station for electric vehicles. The site also includes solar panels and a water treatment unit for reusing water in irrigation and cleaning purposes.
DEWA adhered to the highest indoor air quality standards during construction, using high-efficiency air filtration systems to ensure a healthy and sustainable indoor environment. The mosque was also built using recycled construction materials, supporting DEWA’s commitment to circular economy principles and environmental sustainability.
