Qatari Diar has announced the registration of two world records in the Guinness World Records, related to the district cooling system in Lusail City.
This is a new global milestone added to Qatar's record of achievements in the fields of infrastructure and sustainable development, the company said in a statement.
It added that the integrated district cooling network in Lusail City was registered as the largest district cooling network in the world, with a total length of 123.5 km.
The network connects district cooling plants and energy transfer stations to buildings, through a network of pipes ranging in diameter between 100 and 1600 mm, the statement added, explaining that it is further supported by smart leak detection systems, distributed isolation valves, and service tunnels that strengthen operational flexibility, ease of maintenance, and continuity of service.
The statement further noted that the second world record was registered for the longest chilled water storage tank in the world, where the chilled water tank in the Northern District Cooling Plant in Lusail City was recorded as the world's longest, with a height of 46.041 meters, a diameter of 32 meters, and a capacity of 12,000 refrigeration tons.
The tank plays a pivotal role in enhancing the efficiency of the system by storing chilled water during periods of low demand and reusing it during peak times, contributing to improving energy consumption efficiency by up to 14%, the statement continued.
It pointed out that this achievement is the outgrowth of a strategic vision the company has been pursuing since the launch of the Lusail City project, based on developing an integrated city whose distinction isn't limited to urban planning and design quality, but extends to advanced infrastructure that constitutes the foundation for the city's sustainability, growth capacity, and ability to provide reliable services for future generations. Fully owned by Qatari Diar, Marafeq Qatar has played a key role in turning this vision into an integrated operational reality through the development and operation of advanced utility systems according to the highest global standards, the statement reads.
It noted that this makes the district cooling system in Lusail City today one of the world's leading models in efficiency, reliability, and sustainability.
CEO of Qatari Diar, Sheikh Hamad bin Talal Al-Thani, said Lusail City's entry into the Guinness World Records with two global records represents an important milestone in the path of a national project whose vision was initially based on building an integrated city where infrastructure is a cornerstone of sustainable development and quality of life.
He affirmed that this accomplishment reflects the success of Qatari Diar's vision in long-term investment in cities capable of growth and adaptation to the future.
Sheikh Hamad added that this global recognition suggests the success of integration between urban planning and advanced infrastructure, and confirms the State of Qatar's capability of advancing world-class urban projects that enhance Lusail City's position as a paragon of smart and sustainable cities.
This is alongside the commitment to service quality for subscribers and meeting their needs according to the highest standards, he underlined.
For his part, Eng. Ahmed Al Ammari, CEO of Marafeq Qatar, expressed his pride in this national achievement for the State of Qatar, which the Guinness World Records internationally recognise.
He noted that this milestone suggests the efficiency of an integrated system designed and operated according to the highest global standards, ensuring service reliability and sustainability.
This recognition, Al Ammari added, crowns more than fifteen years of planning, investment, and development, and stands as a testimony to Qatar's progress in infrastructure, Lusail City's advanced urban model, Qatari Diar's ambitious vision turned into reality, and Marafeq Qatar's operational efficiency and specialized expertise in developing and operating utility systems according to global best practices.
Overall, the district cooling system, which is a highly efficient air-conditioning system, is considered one of the pillars of sustainable development owing to its advantages in reducing electricity consumption, conserving resources, and protecting the environment.
Lusail City will include a number of main cooling plants to cover its cooling needs, with a total production capacity estimated at almost 630,000 refrigeration tons upon full completion of the city.
