Cundall has been awarded the engineering and design contract for the second phase of Facebook’s new European energy efficient data centre campus in Luleå, Sweden, close to the Arctic Circle. The data centre, Facebook’s first outside of the United States, includes the fit-out of two mega data halls (Halls C and D in building 1). Facebook looked at several sites across Europe, and picked Luleå for the availability of cheaper 'green' electricity and its cold climate, which supports abundant 'free cooling'. The move will see Facebook become faster for users across Europe.
