Based on industrial water 

Cooling—without chillers—will lower energy consumption for the datacenter and operating costs for our customers.

For reliable cooling, The Green Bay will use two independent water systems. The primary is waste water in the area, which will be recycled to our condensers in water towers. 

Via a heat exchanger, cold waste water will cool fresh water. A system of pipes will bring this cold fresh water to the Computer Room Air-Handler (CRAH) systems. They will use it to chill air and blow it into the computer suites. 

If planned maintenance or an incident makes the waste water supply unavailable, water will be drawn from a large reservoir with 20.000m3 capacity.

If the primary water supply fails, water will be supplied by a back-up (drinking) water supply. 

The complete installation will provide reliable cooling to guarantee a stable operating temperature of 27°Celsius for the computer suites. 

The pipes for fresh-water distribution will be on the ground floor. We will not install water pipes above customer suites. 

The Green Bay designed the datacenter with a sweet spot that balances power and cooling capacity at 1MW per suite, equivalent to about 5.2kW per rack. This exceeds the average design capacity in the market today. But clients are deploying more high-density racks with capacities above 20kW for each one. 

From the standpoint of power supply, this is not a big issue. From a cooling perspective, however, it presents more of a challenge. While it is almost impossible to use air-cooling effectively in this situation, water-cooled racks can do the job.  

The Green Bay will be able to provide cold water to water-cooled racks via the systems on the ground floor. At a customer’s request, we can deliver fresh, cold water to water-cooled racks.
