Fundamental lighting factors and quality criteria form the basis for VDU workstation placement in a room and surface design of furniture and work equipment. Reflected glare limitation can be achieved through different measures. Where it is not possible to limit reflected glare exclusively through lighting-related measures, a suitable arrangement of workstations and work equipment or other measures can contribute to limiting reflected glare on screens and other work equipment.
Arrangement of workstations and work equipment
The following arrangement of workstations and work equipment is recommended:
Screens should be arranged in a way that creates a viewing direction mostly parallel to the windows for the user.
Screens should be arranged in a way that does not leave them directly underneath luminaires which direct a major portion of their luminous flux towards the bottom in a concentrated fashion, e.g. narrow-distribution luminaires.
In the working areas "screen work" and "meeting", there should be no disturbance by reflected glare on the mostly horizontal surfaces where the visual tasks are located (this does not refer to the visual task on the screen). Luminaires which feature high luminance values which are directed towards such surfaces, e.g. narrow-distribution luminaires with high illuminance at a distribution angle of -20° ≤ γ ≤ +20° should not be located directly above the workstations.
