Add Calculations  Unified Glare Rating
The Unified Glare Rating calculations available in AGi32 are calculated in accordance with the CIE document CIE 1171995  Discomfort Glare in Interior Lighting. The shielding effect of the observer's eyebrows and forehead are considered in this calculation. The CIE Unified Glare Rating (UGR) calculation predicts discomfort glare in interior applications from electric light sources. Discomfort Glare is defined as glare that causes discomfort without necessarily impairing the vision of the objects. In other words, you can see the object but may experience discomfort looking at it.
UGR calculations are derived by considering the effect of the luminaire and surrounding environment on an observer's eye. The UGR formula is based on three components:
Specify UGR Grids 
Specify UGR Observers
