Prince Street Technologies Energy-Efficient Factory

When Prince Street Technologies, a subsidiary of Interface Carpet, built a new 160,000-square-foot factory in Cartersville, Ga., they used extensive natural daylighting. Daylight streams into the factory through 32 skylights — a big help for employees making richly colored carpets. A company official brags theirs is “the only carpet factory with a 60-foot picture window. The workers love it . . . It’s made an immense difference in attitude.” In the first three years after moving into the new building workers’ compensation cases dropped from 20 per year to under one per year for savings worth an estimated of $100,000 to $200,000 a year — more than the value of the energy savings.
