SUNTRACKER
SunTracker brings in more light for more hours than any other daylighting system.
SunTracker uses a state-of-the-art solar powered GPS rotation control system to track the sun with a single mirror that effectively reflects sunlight into the building. The light passes through a thermal barrier, through a light well and a bottom light diffuser to effectively spread the light throughout the building.
The SunTracker tracks the sun from an hour after sunrise to an hour before sunset allowing the end user to turn the lights OFF during daylight hours.
Energy Efficient Lighting
Ciralight's SunTracker high performance daylighting system produces up to ten times more light than a passive skylight and distributes light more evenly and over a wider area.
Compared to electric lighting, it produces illumination equivalent to 800 watts of fluorescent lighting, or more than a 1,000 watt metal halide lamp. Since it does not draw any line voltage, electricity costs for lighting drop to zero during the average of 10.5 hours a day that it reflects light indoors.
The combination of lumen performance, low operating cost, long life cycle and much lower heat generation is what makes the system so energy and maintenance efficient. The system is warranted for 10 years.
High-end clothing manufacturer Patagonia, for example, installed Ciralight's SunTracker advanced daylighting system to reduce electricity consumption at their distribution center in Reno, Nevada.
The facility's requirements for artificial lighting dropped by two-thirds and operating costs, including for HVAC, fell by a third. The reason is that the spectral content of natural light produces about 2.5 times as many lumens per Btu of cooling load than electric lighting does.
That savings would avoid producing 618,200 pounds of atmosphere-warming carbon dioxide, 1,793 pounds of nitrogen oxides and 1,076 pounds of sulfur dioxide. Sulfur dioxide and nitrogen oxides pollute the air, creating smog. Nitrogen oxides harm the earth's ozone layer.
Proven Sales Increases
An Ace Hardware store manager in Martinez, CA, reported at least a 10% increase in sales after installing a SunTracker system. In addition, energy savings totaled 4.9 cents kWh/sq. ft.
Proven Productivity Increases
Scientific evidence shows that people feel, work and learn better with daylight than with electric lighting.
Research shows that:
- Retail sales increase from 10% to 40% with daylighting in general.
- School grades increase from 6% to 20% when compared to non day lit classrooms
- Industrial savings include less absenteeism, higher productivity, better safety records
