Predict Sources of Glare

Daylight is not sunlight. The very practice of daylighting assumes some solar control. Traditional glazing, with glass, does not control the sunlight entering a space, often introduces glare issues and is not daylighting at all. To control glare, people use blinds or shades. Louvers or complex lighting controls may be installed. But with daylight modeling, you can predict where glare may be an issue and prevent these additional costs.

Measuring Visual Daylight Glare Probability (DGP) helps to identify potential problem areas where glare is a concern and where visual acuity is critical. Glare may only be an issue during certain times of the year, month or day, in which case your design does not need to be adjusted.

But glare is a major health and safety concern. In schools and offices where people areworking, glare disrupts visual comfort and reduces productivity. In pools, glare can prevent a lifeguard from seeing swimmers in the water. In nursing homes and other spaces, it can cause a trip hazard for the elderly.

Not accounting for glare can be a huge detriment once a building is occupied. Daylight modeling will help you avoid unforeseen issues.
