Low-glare workstation design

Glare is commonly generated when high-intensity electric or natural light reflects off glossy surfaces that may be positioned at suboptimal angles in and around occupant spaces, in relation to windows. The resulting discomfort can be a hindrance to an otherwise comfortable and effective work environment. Adjusting the angle at which the light hits a surface can help guide the light away from reflecting directly into the eye, thereby avoiding glare.

Part 1: Glare Avoidance

The following requirements are met:

a.81 To minimize glare caused by incoming sunlight, all computer screens at desks located within 4.5 m [15 ft] of view windows can be oriented within a 20° angle perpendicular to the plane of the nearest window.
b. Overhead luminaires are not aimed directly at computer screens.
