Up to 350 jobs will be created during the building of a 15-acre data centre in Manor Royal.
Construction on IT firm Rackspace’s huge complex will start soon with the first half due to finish in February 2015.
CrawleyMP Henry Smith delivered the key-note speech at the site’s ground-breaking ceremony on Wednesday (February 19).
He said: “This cutting edge technology company locating to Crawley is a direct endorsement of our positive business environment and is hugely significant for our town, its growing economy and employment.”
Digital Reality, which will build the facility – known as the Crawley Data Centre – will create some 250 jobs for construction workers and project managers.
Up to 100 further staff, such as engineers and lawyers, will also work on the project.
The facility will allow for expansion into additional buildings.
From an environmental stand point, a spokesman said the system used to keep the site cool would be 80 per cent more energy efficient than those normally used in the sector – a fact he felt would help attract clients.
The centre will be the first in the UK to use the technology in this scale.
Michael F Foust, CEO, Digital Realty, said: “The Crawley Data Centre is particularly exciting because of the high level of attention in its design to efficiency and sustainability.
“The potential energy savings are game changing and we’re exceptionally excited about its possibilities.”
Mark Roenigk from Rackspace added: “We are very proud to say we’re involved in building one of the greenest data centres in the UK.
“It’s a huge achievement.”
The campus will have a 10 megawatt(MW) capacity when completed.
Mr Foust said the site’s energy efficiency would cut its operational costs significantly and attract environmentally-conscious clients.
Rackspace will employ around 30 people by this time next year.
The ‘Rackers’ will be involved in building, installing and maintaining IT systems at the site.
