Cooling crays at the University of Edinburgh

Tags: energy | ICT | cooling | computing

The University of Edinburgh’s Advanced Computing Facility, which was expanded in 2007 to house the £113m Hector (High End Computing Terascale Resources) scheme, is a national resource for solving complex research problems.

A range of measures such as free cooling, avoidance of hot/cold air arrangements, and variable speed drives, are saving over £500,000 per annum in energy costs at the Hector site, compared to older, unoptimised, facilities. The free cooling has cut annual energy consumption by 26%, generating a cost saving of £235,000.
