Monday, May 13, 2019. The lumen method determines average illuminance achieved on the workplane using a derived property of luminaire photometrics and room geometry called the coefficient of utilization. The RCR is calculated based on the Room Cavity Height (RCH) and the Lighting Calculation Workplane, which is a property of each space instance.
Average Reduced Air Pollution (g. Sulphur Dioxide) = Energy Savings (kWh) x 5.3 g. Average Reduced Air Pollution (g. Nitrogen Oxides) = Energy Savings (kWh) x 2.8 g.
