Office lighting affects productivity, wellbeing, and energy costs, yet most offices are lit to a standard determined by cost rather than performance. DIALux simulation changes this equation by allowing designers to validate office lighting schemes against occupant comfort standards before installation, identifying problems and optimising performance without the expense of post-installation rework. Lumengraphix uses DIALux as a standard tool on every office lighting project.
What DIALux Simulates in an Office Environment
DIALux allows Lumengraphix to model an office floor in full 3D, including workstations, meeting rooms, corridors, reception areas, and server rooms, each with their own illuminance requirements. The software calculates maintained illuminance at desk height, uniformity ratios across task areas, unified glare rating for screen work, and colour rendering for all specified zones. The result is a complete photometric report that documents compliance with EN 12464-1.
Validating Against Occupant Comfort Standards
EN 12464-1 specifies that office workstations require a maintained illuminance of 500 lux, a minimum CRI of 80, and a UGR of no more than 19. DIALux simulation verifies that the proposed lighting scheme meets every benchmark before a single fixture is ordered, giving clients, architects, and building certifiers the documentary evidence they need.
Modelling Controls and Daylight Integration
Beyond static illuminance calculations, DIALux allows Lumengraphix to model how daylight from windows and skylights contributes to the overall lighting environment. We use this data to design occupancy-responsive and daylight-responsive control strategies that reduce artificial lighting energy consumption without compromising the illuminance conditions that occupants need. This integration is increasingly required by sustainability certifications including BREEAM, LEED, and WELL.
What You Receive from a Lumengraphix DIALux Report
Every office lighting simulation delivered by Lumengraphix includes false colour illuminance maps, 3D rendered visualisations, iso-lux diagrams, luminaire position plans, and a full numerical summary of all calculated parameters. This documentation package supports both design sign-off and any future compliance audits, making it a valuable asset throughout the building lifecycle.
