Lighting Retrofit Saves Data Center 244,000 kWh Over One Year


vXchange, a carrier-neutral colocation provider, has announced that a 2016 lighting retrofit has saved its data center 244,000 kWh over the past year.

The Chappaqua, New York, data center is one of the company’s many data centers that meet required energy efficiency standards as “green data centers,” as certified by the US Environmental Protection Agency.

vXchange used Fairbanks Energy Services for the retrofit. The company replaced 147 2’x4′ recessed troffers with 2’x4′ LED kits equipped with integrated occupancy and daylight sensors at the 38,000 square foot data center. The integrated sensors increased energy savings from the retrofit by more than 20%, allowing fixtures to be grouped together and dimmed down to IES (Illuminating Engineering Society) recommended light levels, according to

Recent lighting news

In July of this year, research was released, finding that data centers can improve their power usage effectiveness (PUE) by up to 25% with energy-efficient LED lighting paired with sophisticated controls and sensors.

Other facilities have recently turned to LED lighting to reduce energy usage. In March, the Department of Energy installed 33,000 LEDs throughout its headquarters in Washington, D.C. in hopes of cutting energy use by 45%.

And in June, a report by The Future of Corporate Real Estate, said LED lighting can reduce energy costs by as much as 80% and environmentally friendly office spaces can often times demand higher rents.
