Automatically populates an array of lights based on a target lux level.
The software allows users to import .dwg and .dxf CAD files to act as structural traces. It also supports basic IFC (Industry Foundation Classes) files, facilitating a smoother Building Information Modeling (BIM) workflow for collaborative engineering projects. 5. Open Luminaire Catalogues
Allows manual placement of single fixtures or spotlights. Set the mounting height and orientation of your fixtures. Step 5: Setting Up Calculation Surfaces dialux evo 82 free
DIALux evo is a professional, high-end lighting design software developed by the German company DIAL GmbH, established in 1989. It has become the global standard for lighting designers, architects, and engineers, with over 750,000 active users worldwide. It allows you to plan, calculate, and visualize light for indoor and outdoor areas—from single rooms to whole buildings, streets, and even emergency lighting, all while taking daylight into account.
Version 8.2 (and the 8.x series) strengthened the ability to import 3D models (IFC files) from BIM software. This allows designers to import architectural layouts and begin designing lighting directly within the 3D model. 2. Enhanced Indoor and Outdoor Visualization Automatically populates an array of lights based on
DIALux has always been famous for its freeware model. The software is funded by partner luminaire manufacturers, meaning the core design and calculation tools are entirely free for commercial and personal use. Step-by-Step Installation Guide
Introduced in version 14, the new room-by-room calculation is a major workflow improvement. Instead of recalculating an entire project for every small change—which is time-consuming for large projects—you can now calculate individual rooms or areas separately. Results are stored and then combined into a final total, making the planning process significantly more efficient, especially for projects with many rooms and numerous luminaires. This feature is included in the free version of DIALux evo 14. Step 5: Setting Up Calculation Surfaces DIALux evo
Select for a single interior space or Outdoor/Building Planning for comprehensive architectural layouts. If you have an existing floor plan, choose Import DWG/DXF to use it as a tracing template. 2. Constructing the Geometry
When placing objects, the software automatically determines their allocation (storey, indoor, or outdoor) based on their position rather than the active view.
Reduces the risk of over- or under-lighting a space.
