Davis & Warshow Unveils US’s First Net-Zero Lighting Cost Facility

September 26 [Wed], 2012, 12:10
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.

Both the installation of the solar array and the LED conversion are part of Davis & Warshow’s “Practically Green” program – a “small-steps” approach to going green that the company inaugurated in 2008. The company says that the successes shown by the initiative so far are proof that even small businesses like D&W make a difference in reducing their environmental footprint.

In August, a General Motors manufacturing facility in Spring Hill, Tenn., announced electricity savings of over $800,000 a year after installing high-efficiency lighting and wireless controls. The lighting upgrade project included replacing nearly 4,500 fixtures with high-efficiency fluorescent lights made by Light Corporation and installing a wireless control system by Kanepi Innovations. The project is expected to save GM more than 8.5 million kWh of electricity a year, preventing annual carbon emissions equivalent to that of 657,088 gallons of gas.

MyLED Opto Technology Sdn Bhd today sealed contracts with two Japanese-owned companies to supply light emitting diode (LED) lighting to vending machines in Japan, with sales expected to reach RM800 million over the next five years.

The contracts from Kirutorisu Tech Sdn Bhd and ATOTIS Co Ltd will enable MyLED Opto, a subsidiary of Ho Wah Genting Bhd, to penetrate into the Japanese vending machine market.

MyLED Opto Chief Executive Officer Jetson Lai said the Japanese partners have estimated that based on their monthly orders of 300,000 units of LED lights, the estimated accumulated order value will be in the range of RM800 million over the next five years, given the high number of vending machines and the strict LED lighting replacement policy in Japan.

"With these orders, the land of the rising sun has become our biggest overseas market.

"With the contracts signed today, our monthly production is expected to increase significantly from 30,000 units to 100,000 units by the end of 2012 and gradually to 300,000 units thereafter," he told reporters after a signing ceremony with its partners here Tuesday, witnessed by Second Finance Minister Datuk Donald Lim Siang Chai.
