DIALux platform for assessing lighting performance and energy use

DIALux lighting design software is now available for download. Planners and engineers can use it to model and calculate indoor and outdoor lighting, assess energy use, and optimise lighting schemes for buildings.

Editorial Team

The DIALux lighting design tool is available for download from the official DIALux portal. The software enables planners, architects and engineers to design, calculate, and visualise lighting schemes for buildings and outdoor areas.

DIALux supports simulation of artificial and daylight lighting for single rooms, whole buildings, and external environments. Users can access photometric data from a large database of luminaires and plan lighting systems in compliance with relevant standards.

The software also includes functions to assess energy consumption and energy-saving potential over the course of the year by taking into account daylight influence and control systems. This allows lighting designers to optimise schemes that can contribute to reduced energy demand in buildings.
