European Lighting Standard EN12464-1

Since 2003 EU member countries have had a common standard (EN 12464-1) for light planning in workplaces. The earlier standards had comprised of lighting requirements for work surfaces, computer monitors and the immediate surroundings. Based on new research, the standard has now been revised and also sets requirements in terms of lighting of ceilings and walls.

At the same time, the lighting should be adjustable in classrooms and lecture halls, and meet the energy requirements of EN 15193:2007. At Fagerhult we believe this is a step in the right direction. But if you want to get the full benefit of light’s positive effects, you need more light than what the legislation requires.

Lighting of the working area

The standard requires an illuminance of 500 lx.

Indirect light in the ceiling (ambient light)

The standard states a minimum illuminance of 30 lx as the requirement and recommends a minimum of 50 lx. To achieve the positive effects reported in Fagerhult’s study, we recommend an illuminance of 300 lx.

Vertical light on walls (ambient light)

The standard states a minimum illuminance of 50 lx as the requirement and recommends a minimum of 75 lx. Based on the findings of our research, we recommend an illuminance of 300 lx.

Cylindrical illuminance (in rooms with demands of good visual communication)

Cylindrical illuminance especially affects visual communication and the ability to interpret faces, events and objects. The standard requires a minimum illuminance of 150 lx in rooms with demands of good visual communication.
