One of the newest green data centers is finally online, the result of a two-year consolidation and refurbishment project at Sun Microsystem’s Broomfield, Colo., facility.

The project involved paring down close to 500,000 square feet of space to 126,000 square feet at the former StorageTek facility, with the goal of reducing costs by $1 million a year and cutting the company’s carbon footprint by 6 percent, nearly 11,000 metric tons of CO2 a year.

The company was able to consolidate 63 servers down to 30, and reduce the amount of raised floor space from 165,000 square feet to only 700.

The center also boasts a non-chemical water-treatment system that saves about 675,000 gallons a year and eliminates dangerous runoff into the environment. The company plans at some point to divert the runoff for other uses, such as facility irrigation.

Also on board is Liebert’s XD cooling system that supports rack loads up to 30 kW, a high-efficiency chiller system and a flywheel-style UPS that operates without batteries.
