ethodology
This analysis draws upon industry forecasts and previous analysis to assess potential savings from the Energy Star Computers program and advanced technology in the most detailed manner justified by existing data.
- We calculate unit energy consumption (UEC) for each type of equipment from the estimated power levels and hours of usage.
- Device densities are computed to be consistent with current and future commercial sector floor stock and industry projections of equipment sales.
- The UECs are then multiplied by the device densities and projected floor area in a given year for a given building type to get the total energy use by building type and device type.
