Results generated by this tool are provided for informational purposes only, without any warranty as to accuracy, completeness, reliability or otherwise.

The Visual Interior Tool is designed to perform lumen method calculations on a rectangular room. 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 lumen method operates under the following assumptions

Luminaires are spaced uniformly
Incident flux on each surface is uniformly distributed over the surface
Room is empty
Surfaces are diffuse
Surfaces have neutral color

Because the lumen method provides an average illuminance, point values for calculations might vary considerably. Please use the professional addition of Visual for full lighting analysis.

Values calculated during the zonal cavity method are shown in the collapsible panel below the Display settings. These values are provided to help those curious about how the zonal cavity method works see the intermediary values that must be calculated in order to perform the calculation. For more information on the lumen method / zonal cavity method consult the IESNA Lighting Handbook.
