Jnayin Nourah Project to Pioneer Open-Space Cooling with PrimeLoop Geothermal Technology
A major new geothermal cooling project in Riyadh is positioning Saudi Arabia at the forefront of next-generation district cooling. The Jnayin Nourah Project, located on the Princess Nourah Bint Abdulrahman University campus, is being developed as the world’s first open-space cooling application using Strataphy’s PrimeLoop geothermal technology.
This is a significant milestone because it combines three things that are rarely brought together at this scale: geothermal cooling, district cooling, and open-space deployment. In a region where cooling demand is enormous and water scarcity is a constant concern, the project could become a powerful example of how innovation and sustainability can work together.
A global first in cooling
The headline claim is bold: this is the first open-space cooling geothermal system of its kind anywhere in the world. The project is being developed through a binding memorandum of understanding involving four parties: Best Land for Real Estate and Investment LLC, Daim Al Athar for Real Estate Co., Saudi District Cooling Company, known as Saudi Tabreed, and Strataphy.
That collaboration matters because it brings together the client, the district cooling operator, and the geothermal technology provider in a single development framework. Best Land and Daim Al Athar represent the project owner side, Saudi Tabreed is responsible for the district cooling infrastructure, and Strataphy is supplying PrimeLoop, its patented geothermal cooling technology.
The announcement suggests that geothermal cooling is moving beyond theory and into practical, large-scale implementation. If successful, the project could become a model for other hot-climate regions that need cooling systems capable of handling rising demand without imposing heavy water or electricity costs.
Why PrimeLoop matters
PrimeLoop is the core technology behind the project. Strataphy describes it as a patented geothermal cooling system designed to make shallow geothermal energy commercially viable for district cooling at scale.
That is important because conventional geothermal cooling has often faced barriers related to deep drilling, high costs, and scale limitations. PrimeLoop is intended to overcome those constraints by using the stable thermal properties of the shallow subsurface instead. In simple terms, it turns the ground into a heat sink that can absorb rejected heat efficiently and reliably.
The company says the system is engineered for developments measured in the thousands of refrigeration tons. That scale is critical because district cooling only becomes transformative when it can serve large, dense projects rather than isolated buildings. By making geothermal cooling suitable for bigger developments, PrimeLoop could help reshape how urban cooling infrastructure is designed.
Why the Saudi climate is the right test
Saudi Arabia is one of the most demanding environments in the world for cooling. High ambient temperatures, rapid urban expansion, and intense peak electricity demand all put stress on infrastructure. In that setting, a system that can deliver reliable cooling around the clock is especially valuable.
PrimeLoop is being promoted as a solution that draws on the constant temperature of the ground, which makes it less vulnerable to extreme outdoor heat. That gives it a major advantage over systems that rely heavily on air temperature or large amounts of evaporative cooling. In a water-scarce region, that matters just as much as energy efficiency.
The project’s appeal is therefore both environmental and operational. It is designed to reduce electricity demand, eliminate water consumption, and provide consistent cooling performance even when outdoor temperatures rise sharply. For the Gulf region, those three benefits are especially attractive.
Water savings are central
One of the strongest features of the project is its zero-water cooling claim. By rejecting heat into the earth rather than evaporating water into the air, PrimeLoop avoids the water consumption associated with conventional cooling towers.
That matters enormously in Saudi Arabia, where every drop of water has strategic value. Conventional district cooling can be far more efficient than individual air-conditioning units, but it still often relies on water-intensive infrastructure. A geothermal approach that removes water from the equation could represent a major sustainability breakthrough.
The company says the approach could eliminate millions of cubic meters of water consumption each year compared with conventional cooling towers. Even without diving into the exact figure, the broader point is clear: this technology is being positioned as a water-resilience solution as much as a cooling solution. That makes it especially relevant for cities and developments in dry climates.
Energy savings and emissions cuts
PrimeLoop is also being promoted as a way to reduce electricity use by up to 50 percent compared with conventional cooling systems. If that performance holds in real-world operation, the implications would be substantial.
Cooling is one of the biggest energy loads in hot climates, especially during summer peaks. Cutting electricity demand by half would not only lower operating costs for developers and users, it would also reduce pressure on the grid. That could improve system reliability and free up capacity for other parts of the economy.
There is also a climate angle. Less electricity consumption means lower emissions, especially where power still depends partly on fossil fuels. In this sense, PrimeLoop is doing two things at once: it is reducing operating expenses and lowering carbon intensity. That combination is often what makes a sustainability technology commercially attractive.
District cooling as the platform
The project is built on district cooling, which is already one of the most efficient ways to deliver cooling in dense urban developments. Instead of each building running its own separate cooling equipment, a central plant produces chilled water and distributes it through a network.
That model offers obvious advantages. It improves efficiency, simplifies operations, and lowers costs compared with many standalone systems. It also reduces grid strain because cooling production is centralized and better optimized.
At Jnayin Nourah, district cooling is being combined with geothermal technology in a way that could push the model further. Saudi Tabreed says it will provide a turnkey district cooling solution with an indicative cooling load of about 10,000 TR, or roughly 35 MWth. That is a sizable load and indicates that the project is intended to serve a major development rather than a small demonstration site.
Why the university campus matters
The location on the Princess Nourah Bint Abdulrahman University campus makes the project especially notable. It is being described as the first geothermal-supported development on a university campus in the Middle East, which adds another layer of significance.
University campuses are often ideal for advanced infrastructure demonstrations because they combine large energy demand, visible public value, and long-term development horizons. They also provide a highly symbolic setting for innovation. In this case, the campus becomes a proving ground for a cooling technology that may eventually be used in other mixed-use or institutional developments across the region.
This matters because successful demonstration projects often begin in environments where performance can be measured carefully and visibly. If Jnayin Nourah works as intended, it could help normalize geothermal district cooling in other parts of the Middle East.
The partners behind the deal
The collaboration brings together four distinct players with clearly defined roles. Best Land for Real Estate and Investment LLC and Daim Al Athar for Real Estate Co. are the consortium representing the client and project owner. Saudi Tabreed brings district cooling expertise and infrastructure execution. Strataphy contributes the PrimeLoop geothermal technology.
That structure is important because large infrastructure projects succeed when responsibilities are clearly divided. The real estate side defines the development vision. The cooling operator manages the infrastructure. The technology provider brings the innovation that can change performance economics.
The companies involved are framing the project as more than a technical partnership. They are presenting it as a strategic step toward a new kind of urban development, one that combines sustainability, operational efficiency, and long-term value creation.
What the executives said
The statements from the participating companies underline the scale of the ambition. Strataphy’s CEO, Ammar Alali, described the project as a landmark moment not just for Jnayin Nourah but for the global cooling industry. He emphasized that the system can cool an entire development with zero water consumption while cutting electricity use by up to half.
Saudi Tabreed’s managing director, Suliman Al Khliwi, framed the collaboration as part of the future of smarter, more sustainable cooling infrastructure. His comments suggest the company sees the project as a practical example of what next-generation district cooling can look like.
From the development side, Ashraf Saleh Bawazir of Best Land highlighted the project’s role in creating a city-of-the-future model, where sustainability and innovation are integrated from the earliest stages of planning. Daim Al Athar’s CEO, Rakan Khaled Al Khalaf, echoed that view, saying the development is intended to set new standards for sustainability, innovation, and long-term value creation.
Why this could change the market
If PrimeLoop performs as promised, the project could influence how developers think about cooling in hot climates. The biggest barriers to innovation in cooling have often been cost, complexity, and uncertainty. A real-world project of this scale could help answer all three.
The technology’s potential lies in its ability to offer reliability, water savings, and energy savings at the same time. That is a rare combination. Most cooling systems improve one thing while sacrificing another. A solution that addresses all three could become attractive not only in Saudi Arabia, but across the Gulf and other arid regions.

This could also strengthen the case for geothermal applications beyond power generation. Geothermal has often been discussed mainly as a source of electricity, but cooling may prove to be an equally important market. In places where cooling demand is huge and water is scarce, the commercial logic may be even stronger.
A milestone for the region
The Jnayin Nourah Project is being positioned as two milestones in one. First, it is the first geothermal-supported development on a university campus anywhere in the Middle East. Second, it is the world’s first implementation of geothermal technology for open-space cooling.
Those milestones matter because they move geothermal cooling from concept to category creation. If the project succeeds, it will not just be a good installation. It will become a reference point for a new type of cooling infrastructure.
For Saudi Arabia, the project also fits broader sustainability ambitions. The country is looking for advanced infrastructure solutions that support urban growth while improving efficiency and reducing environmental impact. Jnayin Nourah fits that ambition neatly.
The bigger takeaway
The most important thing about this project is that it is not trying to solve one problem only. It is trying to solve multiple problems at once: water scarcity, cooling demand, electricity consumption, and sustainable urban development.
That makes it much more than a geothermal announcement. It is a signal that the cooling industry is entering a new phase, one in which geothermal energy may become part of the mainstream toolkit for cities and large-scale developments in hot climates.
If Jnayin Nourah delivers on its promises, it could become one of the most important geothermal cooling projects ever launched. And if it does, it may help redefine what sustainable cooling looks like in the Middle East and beyond.
