To compare calculation results between DIALux4 and evo it is important to consider following points:

1. Is the same geometry used? Is for example a room shaped the same?

2. Is the mounting position exact the same in both projects?

3. Are all parameters the same? These are e.g. the reflection factor of a room and the maintenance factor 

4. By street projects the width of the road should be the same as well as the configured standard and the roadway surface.
