Advanced Data Centers, which snagged a Platinum LEED (Leadership in Energy and Environmental Design) rating for its new data center in Sacramento, Calif., now says it has received the largest ever "Savings by Design" reward for the building from the Sacramento Municipal Utility District. The companies didn't reveal the size of the award, but it will also qualify for a rate reduction, which will be passed on to the customers that Advanced Data Center takes on at the site as it goes live this year.
The new complex includes four buildings, covers 500,000 square feet and provides up to 90 megawatts of power. The first 70,000-square-foot building alone will save up to $2 million in utility costs compared with traditional data center designs, according to Advanced Data Centers calculations. The company also built its own full redundant N+1 substation, which is designed with a total capacity of 45 megawatts.
Bob Seese, chief data center architect for Advanced Data Centers, says the utility recognized the data center's efficiency measures. Among other things, the water in the chillers has been increased, which uses substantial fewer kilowatt hours per ton. Overall, the site covers $0.07 kilowatt hours in power costs. The site uses direct current rotary UPS technology from High-Tech, cutting out a conversion process that wastes electricity. Advanced Data Centers also has taken advantage of an outside air economizer, which can be used 75 percent of the year, enabling them to turn off the chillers.
