Qatari Diar has announced that Lusail City’s district cooling system has secured two Guinness World Records, with the integrated district cooling network recognized as the world’s largest and its chilled water storage tank named the world’s longest.
According to Qatari Diar, the Lusail district cooling network spans 123.5 km, making it the largest district cooling network in the world. The network connects district cooling plants and energy transfer stations to buildings through pipes ranging from 100 mm to 1,600 mm in diameter.
It is supported by smart leak detection systems, distributed isolation valves, and service tunnels designed to enhance operational flexibility, maintenance, and service continuity. The company stated that the achievement marks a milestone for Qatar’s infrastructure and sustainable development efforts.
The company said that the second Guinness World Record was awarded to the chilled water storage tank at the Northern District Cooling Plant in Lusail City. The tank measures 46.041 meters in height, 32 meters in diameter, and has a storage capacity of 12,000 refrigeration tons, making it the world’s longest chilled water storage tank. The tank stores chilled water during periods of low demand and releases it during peak consumption, improving energy efficiency by up to 14 percent.
The company added that Marafeq Qatar, a wholly owned subsidiary of Qatari Diar, played a key role in developing and operating the city’s utility infrastructure, making Lusail’s district cooling system a global model for efficiency, reliability, and sustainability.
CEO of Qatari Diar, Sheikh Hamad bin Talal Al-Thani, commented that 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.
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.

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 recognize. 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.
District cooling is a high-efficiency air-conditioning system that supports sustainable development by reducing electricity consumption, conserving resources, and lowering environmental impact. Upon full completion, Lusail City’s district cooling network is expected to include several main cooling plants with a combined production capacity of nearly 630,000 refrigeration tons.
