Users import photometric files (LDT or IES format) from manufacturers. Luminaires can be placed individually, in lines, in fields, or arranged automatically by the software to target a specific lux level based on international standards (such as EN 12464-1 for indoor workplaces). Step 4: Calculation and Analysis
Optimizes the number and placement of lights, directly contributing to lower operational costs. Designers can construct or import an entire architectural

DIALux evo 9 features an enhanced daylighting model. It calculates the impact of natural light based on specific geographic coordinates, time of day, and sky conditions (CIE sky models). This allows for precise planning of daylight-dependent control systems, helping projects meet LEED and BREEAM sustainability standards. Real-Time False Color Rendering
is a landmark version of the globally recognized, free lighting design software used by professionals to plan, calculate, and visualize light for indoor and outdoor spaces. This update, following version 8.2, introduced significant improvements to the workflow, visualization tools, and documentation . Key Features and Improvements in DIALux evo 9
Execute the calculation engine. Once processed, inspect the visual output using false color renderings, isoline plots, and 3D value charts. These visual aids quickly highlight under-illuminated zones, excessive glare, or hotspots. Phase 5: Documentation and Reporting
