If you are a student, it is free and represents the industry standard you must learn. If you are a professional, staying on an older version means you are working slower, producing less accurate glare calculations, and delivering inferior visualizations to your clients.
Furthermore, the speed improvements in evo 9 make "iterative design" practical. Previously, a designer might try two lighting layouts for a factory. Now, they can try ten layouts in the same time, optimizing for energy efficiency (kWh/year) and visual comfort simultaneously. Unequivocally, yes. dialux evo 9
DIALux evo 9 is not a minor version bump. It is the most significant performance upgrade in the software’s history. It removes the friction from lighting design. The calculation engine is so fast that it encourages experimentation, and the BIM integration is so clean that it bridges the gap between architects and lighting planners.
