Johnson Controls published analysis arguing that zero-water cooling systems are viable and preferable for data centers, citing advances in air-side and refrigerant-based thermal management that eliminate the need for evaporative cooling water. The company positions its approach as a response to regulatory and community pressure over water consumption at large facilities. The piece arrives as water usage effectiveness metrics face increasing scrutiny from state regulators and local governments.
Water consumption has become a flashpoint in data center siting debates across multiple states, and a credible zero-water cooling path would remove one of the most common grounds for community opposition and permit denial. If Johnson Controls' systems can scale to hyperscaler rack densities, it could shift procurement decisions industry-wide.
Keywords 'zero water usage,' 'data center,' and 'cooling' triggered selection. The story was ranked above the Rika water monitoring piece because it addresses a broader architectural shift rather than a component-level monitoring product, with more direct implications for siting and regulatory compliance.
