| TOUR | _ __ Atrium Intense computer
environments demand good lighting. To accommodate a stressful twenty four hour a day
workplace RTLD designed a combination indirect system. Striving to create visual comfort,
interior surfaces brightness levels are matched to the level of the computer monitor
brightness. Eye fatigue is reduced using this general criteria. Two separately controlled
indirect fluorescent systems were used to overcome certain problems. A radial pattern of
linear indirect fixtures with an elliptical profile was chosen by RTLD to liven up the
spatial dynamics of the environment and to compliment the domed ceiling in the center. The
linear fixtures provide the primary component of light and are controlled by an electronic
dimming system. A number of wall recessed rectangular wall washer fixtures added to fill
in the perimeter areas and to illuminate the undersides of the linear system. This
eliminates the contrast of the otherwise dark undersides of the linear light units. The
center ceiling section is domed with an indirect cove supporting end to end asymmetrical
reflector 50 watt biax fluorescent modules. A specified blue neon circle was deleted from
the center dome due to cost restrictions. Additionally, it is important to add
elements of interest as indirect systems tend to produce a veil of shadowless flat
light. There remains much to learn regarding the physical and physiological effects of
long term exposure to electronic devises as they now encroach rapidly into our
environments.
