Google Data Center, Hamina, Finland
This former paper mill was chosen for its sprawling floor space but also for being sited directly on the Gulf of Finland, source of an inexhaustible supply of frigid water for cooling the facility’s servers. This involves pumping the water through a 450-meter tunnel to heat exchangers where the fresh water that actually circulates within the server area is cooled by the seawater before the fresh water is recirculated. The warmed seawater is remixed with cold water from the bay to cool it closer to bay temperatures before it is returned, reducing the environmental impact of warm water. The facility has no compressors or refrigerants for its cooling. Oh, and it has a sauna on site for employees.
