The IT systems for the London Olympics in 2012 will be the most environmentally friendly yet, says the games' integrator Atos Origin.
The company plans to build on its experience with the just-completed Beijing Olympics to reduce IT power consumption for the London Games.
Jeremy Hore, Atos Origin's chief integrator for the Beijing Games, told ComputerWeekly that reducing the computer hardware and cooling required was one of the project's objectives.

"We have made a good start, but there is still more that can be done for the London Games by working from the start to optimise hardware use even further and make it as lean as possible," he said.
Hore, who has spent the past four years in the Chinese capital, said there were big benefits from getting involved with the local Olympic committee very early on.
The Atos Origin team charged with managing the IT for the London games is to begin work officially in November, but started talking to local organisers a year ago.
One winning strategy in Beijing, that Atos hopes to replicate in London, was spending 200,000 hours on systems testing before the Beijing games.
"We did a lot more testing in Beijing then previous Olympic Games and that helped ensure we were 100% ready for the start on 8 August," he said.
This involved a test event that was a real competition for each Olympic sport at the venues that were used for the games as well as several technical rehearsals.
These rehearsals tested the IT team's ability to deal with 500 problem scenarios such as the disqualification of an athlete or the loss of a network connection to a venue.
Although it is impossible to test for every potential problem, Hore said the extensive test programme meant the IT team had at least 90% covered.
Although Hore is moving to other projects at Atos Origin, his successor in the role for the London games will benefit from his experience gained at Beijing.
