Assessment of Discomfort Glare from Daylight in Buildings

Glare models developed for electric lighting conditions are not applicable to daylight situations. This report summarizes the daylight glare prediction models which were confirmed by independent studies.

Evaluating Discomfort From Lighting Glare

Batiment International, Building Research and Practice, 1983
A brief account is given of the purpose and significance of research on glare, particularly its influence on production, as well as the four factors for evaluating the degree of discomfort from glare. Mention is made of me arrangement of equipment, the conditions for experiments and the process of obtaining mathematical expressions for glare evaluation.

Discomfort Glare: Duration-intensity Relationship

Journal of the Illuminating Engineering Society, 1978
The purpose of this experiment was to determine the relationship between comfort and discomfort for glare (BCD) and the duration of exposure to the glare source. The research results show a general conformity to an expected duration-intensity for noxious stimuli.

Discomfort glare from interesting images

Lighting Research & Technology, 2005
In laboratory experiments, subjects viewed bright images projected on to small screens. The projected images ranged from neutral patterns to complex scenes. There was a greater tolerance of discomfort glare from images previously judged ‘interesting’ by an independent subject group than from other screen images giving the same calculated glare rating ...

Discomfort glare prediction by using Unified Glare Rating

Australian Journal of Electrical and Electronics Engineering, 2018
Glare which affects comfort or causes distraction is known as discomfort glare and glare which affects the ability to see any object is known as disability glare.

Discomfort Glare and Visual Performance

Transactions of the Illuminating Engineering Society, 1968
An experimental study was carried out to determine whether glare which had been scaled for discomfort would produce a decrement in visual performance. Three levels of glare and a no glare condition based on the IES glare index classification were established in a carefully controlled visual environment.

Discomfort glare from small light sources

Lighting Research and Technology, 1999
Glare from very small sources is grossly overrated by the UGR (Unified Glare Rating) formula. Experiments were carried out on glare from small sources at interior lighting distances. Results varied widely but were of adequate statistical accuracy. They showed that a small glare source is characterised by a constant projected area of 0.005 m2, not a ...

Discomfort Glare in Lighted Streets

Transactions of the Illuminating Engineering Society, 1940
Glare which affects comfort or causes distraction is distinguished from glare which affects the ability to see. The results of an investigation to determine the factors which cause discomfort glare in lighted streets are summarised, and the influence of these factors on problems of street lighting design is studied.

Prediction of discomfort glare from windows

Lighting Research & Technology, 2003
Visual discomfort in a day-lit interior environment is usually represented by the degree of discomfort glare perceived by the user. The paper reports on the evaluation of several models for the prediction of discomfort glare from daylighting, using data collected over a 10-month period, in a purpose built test cell.
