To compare calculation results between DIALux4 and evo, the following points should be checked: 

  1. Are all geometries (room, etc.) identical?
  2. Is the mounting position of the luminaires exactly the same in both projects?
  3. Have all parameters been set the same? These include, for example, the reflectance of a room and the maintenance factor.
  4. For road projects, the roadway should have the same width. Care should also be taken to ensure that the same standard and road surface are used.
