contrasted similar sized (3,500) PowerMAN and Verdiem projects at the University of Sussex and the University of the West of England with payback periods of 0.5 and 2.5 years respectively. The University of East Anglia Sustainable ICT Service Provision project reported a decrease of up to 40% in PC energy costs. This equated to an average annual saving per PC of 269 kW·h and a reduction in running costs of £27 per year. The report concluded that when applied to all student IT areas this would reduce CO2 emissions by 188,111 kg and running costs by £35,496. The University of Oxford Low-carbon ICT Project conference 'Keeping IT Clean' studied a number of competitor PC power management products and included a university led case-study on PowerMAN References External links System software
