Green House Data Case Study


Green House Data


Founded in 2007, Green House Data is a cloud hosting and colocation services provider with highly energy efficient, and sustainable data centers located across the U.S. The company provides the high-availability infrastructure needed for IT operations while remaining a transparent, responsibly operated company.

The Situation

Cloud hosting and colocation providers need to deliver agility, responsiveness and 100 percent uptime service level agreements to their customers, and they must provide these benefits economically. When fast-growing Green House Data built a new data center in Cheyenne, Wyoming, they wanted the most efficient infrastructure possible, consistent with the company’s commitment to sustainability. To further their strategy for cooling efficiency while staying cost competitive, Green House Data chose an Emerson Network Power free-cooling solution.

Designing a 35,000 square-foot, five-megawatt data center that uses as little energy as possible is no simple task. Green House Data wanted to adopt an efficient thermal management system that would use outside air and minimal amounts of water 365 days of the year.


Liebert Indirect Evaporative Free-Cooling air handlers now support many Green House Data clients. The system uses 90 to 95 percent less energy compared to conventional data center air conditioners and has been instrumental in pushing the PUE down to the target 1.14.

“The Liebert air handlers allowed us to avoid building a central cooling plant, they matched our modular build design, which is important for both environmental and capital efficiency, and they enabled us to more tightly control the data center temperature and humidity.”
- Cortney Thompson, Green House Data Chief Technology Officer
Case Summary
Location: Cheyenne, Wyoming
Products and Services: Emerson Network Power Solutions:
Utilized a close working relationship with Emerson Network Power and industry-leading engineering expertise, working closely with Green House Data to design, manufacture, install and commission a thermal management system customized to meet their specific needs.
Deployed four 300kW Liebert® Indirect Evaporative Free-Cooling air handler units, with the ability to add up to 14 more units to grow with data center requirements. The highly efficient, aluminum air-to-air heat exchangers offer up to 66 percent efficiency in dry mode and up to 78 percent efficiency in wet mode, resulting in a possible mechanical PUE of less than 1.2 and minimal water usage.
Critical Needs: Green House Data’s available whitespace was dwindling in their original Wyoming data center because of the growing demand for the company’s high-touch, customized IT solutions. To accommodate client growth, they built an additional data center, planning the new space based on lessons learned from the first location.
