CalcZone, online Zonal Cavity Calculation. CalcZone is a zonal cavity (lumen method) calculation tool*. Quickly estimate light level (illuminance), number of luminaires, and lighting layout, for a simple room or building - then print a detailed one-page report.
Note that the use of the zonal cavity lumen method is limited to a rectangular space with one fixture. For more complex calculations or for a detailed "point-by-point" calculation a more robust lighting calculation program such as AGI32 or Lumen Micro must be used.
