Harvesting daylight for indoor use is not new. Harvesting daylight economically is new.
The result of American ingenuity, the SunPort is an integrated, patented product with worldwide applications. SunPort systems are rugged, leak free, through-the-roof luminaries that collect sunlight through a prismatic roof-top lens that directs it downward. The sunlight is diffused and distributed into the interior space as cool comfortable light.
The design and construction of the SunPort products has evolved over the past ten years in active use at a wide range of facilities. The project list covers schools, offices, super markets, military bases, warehouses, wineries and retail. (For more information, read through our projects section.)
The SunPort Series brings all the benefits of natural light inside -- at reasonable costs and with minimum modification to existing or new construction. Only two to three percent roof penetration will provide up to 150 foot-candles of light in the summer and up to 40 foot-candles in winter months. Advanced lighting design software allows up to 800 square feet of coverage. The electrical power to the lights can be turned off an average of 7-9 hours based on geographic location.
A SunPort system brings well-diffused UV inhibited light through an insulated light well that is highly reflective (95 percent) and distributes the light into the interior space through the SunPort diffusion lens. The integrated lighting system creates a cool diffused light that covers more than five to ten times the area of a conventional skylight.
The SunPort 2 system integrates a fluorescent light source for supplemental electrical light that is combined with a photo-sensor control system for optimum daylight harvesting. The control system can maintain a pre-set foot-candle specification for multiple zones in the same space.
The SunPort 2P will offer a "parabolic louver" to enhance the architectural offering of the product line.
SunPorts save energy and money by reducing virtually all the energy used to light a building during day light hours including reduced HVAC energy from the reduced heat load with lights turned off. When replacing HID systems, the SunPort system can save up to 85 percent and have a significant impact on lighting maintenance costs. When replacing an existing fluorescent systems the savings can be as much as 70 percent reduction in direct electrical usage.
Peak hour Kilowatt load reduction, the driving force behind energy conservation, approaches 100% during normal business hours from May to October during prime daylight hours. Savings from a SunPort system usually cover the cost of investment with a period of three to five years. Local utility incentives often times improve the project pay-back to below the three-to-five-year estimate.

The SunPort system is designed for easy installation and minimum maintenance over the course of the useful life cycle. This means that once a SunPort is installed there is very little to do to maintain the performance of the unit. All projects using the SunPort 2 include a recommended lamp maintenance schedule. Typically lamps last four times longer than normal due to the low run hours required. The SunPort 1 and SunPort 2 products have an estimated useful life of twenty years.
