Photometric analysis settings

Photometric analysis allows one to get an idea of the quantitative aspects of light. Most software programs have a variety of simulation settings. For example, AGi32 has three simulation settings: full calculation mode, direct only calculation mode and direct auto calculation mode suitable for exterior lighting. Direct calculation mode is a “simplified calculation technique” where reflected light is not considered. Full calculation mode is required for rendered results, and is capable of predicting the interaction of light with reflective surfaces in any environment. Ways to produce quantitative output using lighting design software programs are:

  • Compute illuminance, exitance, and daylight factor using most lightinG simulation software programs.
  • Develop isoline (lines of equal value) diagrams providing contouring capabilities to illuminace values, exitance values, luminance values, and daylight factor values..
  • Add calculation points using a 2-point input or a 3-point input, or along lines or inside polygons.
  • Numerical analysis in terms of average illuminance, maximum-minimum illuminance, average-minimum ratio, maximum-minimum ratio can be conducted.
