Big Ass Fans certainly qualify as green products (they enhance cooling by up to 25% at about the same rate of energy consumption as a single refrigerator light bulb). But their facility is also a green marvel. Recently awarded a LEED Gold plaque, their testing facility in Lexington, Kentucky, uses 35% less energy and 60% less water than a standard commercial building.
