Sustainability is a driving force in modern construction. DIALux 4.13 includes an energy evaluation feature that calculates the lighting power density (W/m² per 100 lux). This helps designers ensure their projects meet green building certifications Sustainability is a driving force in modern construction

DIALux 4.13 is incredibly lightweight. It does not require a high-end GPU or massive RAM. For large industrial halls, parking lots, or street lighting projects with thousands of luminaires, version 4.13 calculates significantly faster than evo. The parametric engine is less graphically intense but more numerically robust.

| | Explanation | |---------------|-----------------| | Stability & Speed | For large, repetitive projects (e.g., warehouse lighting, parking garages), DIALux 4 is often faster and less resource-intensive than DIALux evo. | | No Online Requirement | Works entirely offline after installation, unlike evo which requires periodic online validation. | | Familiar Workflow | Long-time users who mastered the classic interface can work very quickly without learning the evo paradigm. | | Low Hardware Needs | Runs on older laptops or office PCs that cannot handle evo’s demands. |
