【正文】 e 3 Methodologies ? To include: ? a calculation methodology of energy consumption saved through ICT utilization。 ? the definition of basic units relevant to the cases considered。 ? the identification, gathering and processing of relevant parameters (. user behavior)。 ? the principles and tools to measure and evaluate the results。 ? a list of examples of the uses of how ICTs can replace or displace other energyconsuming technologies/uses。 ? analysis of existing standards and a proposal for development of new standards, if needed. Relevant metrics and Units ? Power unit: 1 W = 1 kg m2 s3 ? Energy unit: 1 J = 1 ? 1 kWh = 3,600,000 J ? Mass unit: 1 kg or 1 t = 1,000 kg ? Volume unit: 1 m3 = 1,000 L ? Carbon Dioxide (CO2) = 1 CO2e ? Methane (CH4) = 25 CO2e ? Nitrous Oxide (N2O) = 298 CO2e ? Sulfur Hexafluoride (SF6) = 22,800 CO2e ?
