Case Study: Green House Data achieves 1.14 PUE with Vertiv Liebert Indirect Evaporative Free Cooling

Green House Data - Customer Case Study

Green House Data, a cloud hosting and colocation provider founded in 2007, built a new 35,000 sq. ft., 5 MW data center in Cheyenne, Wyoming and needed highly efficient, sustainable cooling that would use outside air year‑round, minimize water use, preserve sellable white‑space and meet an aggressive PUE target of 1.14. To meet those goals they evaluated and selected Vertiv’s Free Cooling solution, specifically Liebert® Indirect Evaporative Free Cooling air handlers, for a modular, high‑availability thermal management approach.

Vertiv worked with Green House Data to design, manufacture, install and commission four 300 kW Liebert units (900 kW capacity with 300 kW redundancy) placed outside the building and scalable up to 14 additional units. The Vertiv system—featuring high‑efficiency aluminum heat exchangers—reduced cooling energy by 90–95% versus conventional CRACs, helped achieve the targeted PUE of 1.14, delivered up to 64.5% lower energy costs versus an average data center, preserved interior space and supported the facility’s 100% uptime SLA.
