Data centers run hot, all day, every day. Servers operate round-the-clock, and any sudden rise in room temperature can bring operations to a halt. One Texas data center found a possible fix for this problem: paint. The startup, EnKoat, coated the roof of the 110,000 sq ft structure with a product called IntelliKoat. According to EnKoat cofounder Matthew Aguayo, the room temperature fell from 140°F to 86°F and heat-related equipment failures dropped to zero. That claim appears in an April 20, 2026 feature by the National Laboratory of the Rockies (NLR), the U.S. Department of Energy lab renamed from NREL in December 2025, which quoted the cofounder. The piece was primarily about a separate rooftop coating pilot at a New Jersey warehouse, where NLR's own sensors are measuring results directly; the Texas numbers are Aguayo's company-reported figures, cited as prior context rather than independently verified by NLR.
