September 25, 2012 - Kitchen and bathroom supplier Davis & Warshow has converted its entire 209,000-square-foot Queens, N.Y., distribution center from fluorescent tubes to LED tube lighting.
The company says it now has the largest single-facility LED tube installation with the most energy-efficient lighting in watts per-square-foot in the US. It is also the country’s first facility to achieve net zero lighting costs with LED tubes, thanks to a rooftop solar array installed in 2010 that provides more energy that the 200,000 annual kWh needed to power the lighting, the company says.
Davis & Warshow used products made by Independence LED in the retrofit. Prior to the conversion, lighting equaled nearly 65 percent of the structure’s total power usage, costing almost $50,000 per year. It now has decreased to less than 50 percent of the building’s total energy use and costs less than $20,000 per year to run – reducing the company’s lighting tab by nearly $40,000 a year, according to D&W.
The project cost more than $250,000 to complete. With rebates and energy savings, the project will have paid for itself in five years, according to D&W. read more>>>
