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 (0.75) and the standard effective duration (15 years).
Annual Electricity Consumption
The annual electricity consumption is calculated from the product of the daily electricity consumption and 325 days per year.
Daily Electricity Consumption
The daily electricity consumption is calculated from the energy consumption for initial filling, the energy consumption per cycle, the number of cycles per day and the electrical power consumption in standby mode.
