This accomplishment signifies that the building performs in the top 25 percent of similar facilities nationwide for energy efficiency and meets strict energy efficiency performance levels set by the EPA. In 2011, NTT Global Data Centers Americas was the only ENERGY STAR certified data center focused on multi-tenant collocation services.
NTT Global Data Centers Americas earned the U.S. Environmental Protection Agency's ENERGY STAR certification in 2011 and 2012 for both of our Sacramento, CA data centers in recognition of our energy efficiency efforts, demonstrating our commitment to energy efficiency innovation.
Commercial buildings that earn EPA's ENERGY STAR certification use an average of 35 percent less energy than typical buildings and also release 35 percent less carbon dioxide into the atmosphere. NTT Global Data Centers Americas first Sacramento data center facility leveraged energy efficient design improvements to garner over 8 million kWH of energy savings – equivalent to the annual greenhouse gas emissions from 1,447 passenger vehicles. Given the power density requirements specific to data centers, an organization-wide commitment to energy conservation and efficiency is required to successfully earn the EPA ENERGY STAR certification.
NTT Global Data Centers Americas improved its energy performance by teaming with Johnson Controls and Synapsense to improve data floor environmental monitoring and chiller efficiency. NTT Global Data Centers Americas also worked with Schneider Electric to retrofit HVAC plant pumps with variable frequency drive motors which resulted in increased energy efficiency. These cost effective and energy efficient improvements were also implemented in NTT Global Data Centers Americas newest 150,000 square-foot data center in northern Virginia.
EPA's ENERGY STAR energy performance scale helps organizations assess how efficiently their buildings use energy relative to similar buildings nationwide. A building that scores a 75 or higher on EPA's 1-100 scale may be eligible for ENERGY STAR certification. Commercial buildings that can earn the ENERGY STAR include offices, bank branches, data centers, financial centers, retail stores, courthouses, hospitals, hotels, K-12 schools, medical offices, supermarkets, dormitories, houses of worship, and warehouses.
ENERGY STAR was introduced by EPA in 1992 as a voluntary, market-based partnership to reduce greenhouse gas emissions through energy efficiency. Today, the ENERGY STAR label can be found on more than 60 different kinds of products as well as new homes and commercial and industrial buildings that meet strict energy-efficiency specifications set by the EPA. Last year alone, with the help of ENERGY STAR, Americans saved $18 billion on their energy bills while reducing the greenhouse gas emissions equivalent to those of 34 million vehicles.
