f | Factor | — |
nw | Usage intensity | Zyklen/a |
Ns | Standard effective duration | a |
SAE | standard annual energy consumption | kWh/a |
Calculation Formulas
Creditable Electricity Savings
The creditable electricity savings result from the difference between the current and new annual electricity consumption, multiplied by the reduction factor and the standard effective duration.
Annual Electricity Consumption (with EEI)
The annual electricity consumption is calculated from the product of the energy efficiency index and the standard annual energy consumption.
Annual Electricity Consumption (alternative)
Alternatively, the annual electricity consumption is calculated from the product of the specific electricity consumption and the usage intensity.
