Calculation Formulas
Annual Electricity Consumption Sports Field Lighting
The annual electricity consumption results from the total installed power multiplied by the annual usage hours.
Installed Power
The required installed power results from the required illuminance multiplied by the playing field area, divided by the system efficiency.
Annual Electricity Savings
The annual electricity savings result from the difference between electricity consumption before and after the measure.
Cumulative Electricity Savings
The cumulative electricity savings result from the annual savings multiplied by the standard effective duration and the correction factor.
