SolarTrac® System operating on a typical day

2:40 p.m.

SolarTrac® positions shades on the south elevation ¾ down. Shades on the west elevation are adjusted to the 1st position, ¼down. The light-dimming system senses enough daylight for the overhead lights to remain off.

3:20 p.m.

SolarTrac® lowers the shades on the west elevation ¾ down. Shades on the south elevation begin to turn on as the sun angle becomes lower in the west.

4:35 p.m.

SolarTrac®—in reaction to the solar-gain and glare conditions that occur at sunset—lowers the shades on the west elevation to the full-down position. Shades on the south elevation ¾ down. In response to the light conditions, the light-dimming system turns on some of the lights while leaving others off.

5:45 p.m.

At about dusk, the sun is below the horizon. SolarTrac® reacts by raising the shades on the west elevation and shades on the south elevation (left foreground of image) to the full-up position. This provides occupants with exterior views and allows natural daylight to enter the interior
