Results and Configuration Details:

Savings are made possible by Intel® vPro™ processor technology allowing systems to be fully managed whilst powered off and powered back on in a coordinated way to be patched overnight or to get ready for the start of business. Calculations assume a 52- week year and that IT departments will be able to switch systems off only for 12 hours overnight, during regular work weeks, from Monday to Friday (8pm till 4am), and from 8pm on Fridays till 4am on Mondays during the weekend. Public holidays are excluded so additional savings can be made if systems are also switched off during those times. The maximum power saving is calculated as the difference between normal operational* power (as specified by HP on the system specifications below) and the hibernation or powered-off power draw of the system as per these specs. The cost taken into consideration here is an average business electricity cost in the UK of £0.074/KWh. The Kg of CO2 saving is calculated using the UK electricity supplier’s Co2 emission average, which is indicated to be 0.461 kg/kWh as per the fuel mix disclosure, which was set up by OFGEM and the Department of Trade and Industry (DTI) and it requires all suppliers, from 1st October 2005, to produce information on the mix of fuels used to generate their electricity along with environmental information. The information related to this tariff compared against the UK average is shown here: http://energylinx.co.uk/energycalc.html?go=fuel_mix&db=electric&supplierRef=649

* Calculations as per the HP** dc7700 small form factor system as specified by HP here: http://h18000.www1.hp.com/products/quickspecs/12543_na/12543_na.HTML.
