UGR: Unified Glare Rating
UGR stands for Unified Glare Rating. This value is an indication of the extent to which luminaires and light sources cause lightning from a certain position of the user. This value is based on regular patterns and fittings according to the new European recommendations for indoor lighting:
EN 12464-1 standard.
What is the importance of the UGR value?
Lighting is an often underestimated component within companies, but deserves more attention. The productivity and well-being of an employee is greatly influenced by lighting. The light must be so clear that one can perform work, but at the same time one should not be blinded. The UGR value is therefore essential in a company.
What factors play a role in determining the UGR value?
1.Measuring the UGR value depends on certain things. To make a targeted assessment, the following factors play a role:
2.Shape and size of space
3.Surface brightness (luminance) of the walls, the ceiling, the floor and other large planes
4.Type of luminaire and shielding
5.Distribution of luminaires over space
The following UGR values may not be exceeded per application:
UGR value Application
Drawing room: 16
Office works: 19
Fine industrial work: 22
Average industrial work: 25
Circulation areas and corridors: 28
The UGR value differs by each workplace environment, due to the work actions performed. For example, the UGR value in stairwells is higher, because less time is spent and practically less work is achieved.
