Standard EN 12464-1

Since 2003, EU member countries have had a common standard for lighting planning of indoor workplaces. A new version was published in August 2021 and entered into force in February 2022. We have summarized the new European standard standard below.

Calculation areas

The requirements in the standard mainly relate to the actual working area. The lighting outside of the working area shall then be adapted to the conditions that apply within the working area. In the new standard, the relationship between these is clearer.

Glare

Glare occurs when a part of the interior is significantly lighter than the room’s luminosity in general. In this position the eyes are exposed to a stronger light than what they are normally adapted to. The most common causes of glare are that the luminaires and window are seen directly or via reflections within the normal field of vision.
