List of LEED Data Centers (Updated)

Add Your Comments

A small but growing number of data center facilities have earned the Leadership in Energy and Environmental Design (LEED) rating from the U.S. Green Building Council (USGBC). The LEED standard was designed for commercial office buildings, but a coalition of data center industry groups has released a draft of an energy-efficiency standard to expand the program with customized specs for data centers.

LEED Certified Data Centers: The following data center facilities have been certified under the LEED standard:

  • Fannie Mae Urbana Technology Center: In 2005 this 247,000 square foot facility became the first data center to earn LEED certification. The FNMA Technology Center, located in Urbana, Md., is a mixed-use facility with both office and data center components, a trend seen in a number of LEED-certified data centers, as the office component makes it somewhat easier to meet the standards.
  • Highmark Data Center (Silver): This 87,000 square foot facility includes office space and 28,000 square feet of raised-floor technical space. The data center in West Hanover, Pa., which opened in November 2005, processes 500,000 claims per day. It was the second LEED data center, and the first to earn a LEED Silver certification.
  • The U.S. EPA National Computer Center (Silver): This facility in North Carolina’s Research Triangle Park provides large-scale computing services for the EPA nationwide. NCC also supports regulatory program offices and administrative activities, as well as advanced supercomputing for scientific research in air quality protection and other environmental studies. A 2007 upgrade added solar panels on the roof.
  • Digital Realty Trust Chicago Project (Gold): This 20,000 square foot build-to-suit facility within Digital Realty’s 350 East Cermak Road carrier hotel became the first data center to be certified for LEED Gold status.
  • Monsanto Headquarters Data Center: The company spent $21 million building a green data center facility at its headquarters campus in Creve Coeur, Mo. You can check out a time lapse video of the data center construction.
  • Advanced Data Centers is building a 237,000 square foot data center at McClellan Park on McClellan Air Force Base in Sacramento, California. The USGBC has pre-certified the ADC facility for a LEED score of 50 points, above the 45 points required for LEED Platinum, the highest certification tier.
  • 60 Oxford Street, Cambridge, Mass. is a 9,000 square foot data center on the campus of Harvard University that is LEED-certified and houses the university’s Network Operations Center and the Server Operations Center.
  • Citigroup Data Center in Georgetown, Texas (Austin market). This $450 million facility has received LEED Gold certification, and is one of several new Citigroup facilities designed to achieve LEED status.
  • Citigroup Frankfurt Data Center achieved LEED Platinum certification. the 230,000 square foot facility features a green roof and green wall. Citi invested $232 million in the construction of the facility.
  • The American College Testing data center in Iowa City, Iowa has received a LEED Platinum certification. The 8,000 square foot facility uses an unusual geothermal cooling system. 
  • The Honda North American Data Center in Longmont, Colorado has been awarded a Silver rating. The Longmont data center is a Tier III facility, with a 18,700 square foot computer room will ultimately support 1.6 megawatts of equipment load. The facility uses a flat plate heat exchanger to provide free cooling when the outside temperature allows, reducing the use of chillers for approximately half the year.


Proposed LEED Data Centers: The following facilities are under development, but are designed and engineered to achieve LEED certification:

  • Digital Realty Trust (DLR) expects two data centers currently under construction to achieve LEED status upon completion this year: a data center in Chicago with 54,000 square feet of raised-floor space and 6,750 kW of IT load, and a northern Virginia facility with 32,000 square feet of raised-floor space and 4,500 kW of IT load.
  • 365 Main, Newark, Calif. Data Center: 365 Main said its new data center in Newark, Calif. will be LEED-certified when it is completed later this year. Design and construction has begun on the 136,410-square-foot facility.
  • Power Loft@Innovation: Power Loft LLC expects its new data center in Manassas, Virginia to gain Silver LED certification. The project features advanced power management features (including DC power distribution) and will have a green roof and green screen exterior
  • Digital Realty, Santa Clara: The first phase of this project at 1500 Space Park Drive includes a retrofit of 50,800 square feet of existing structures on 7 acres of land. The project was developed by Pelio & Associates, and Digital Realty Trust bought a 50 percent ownership interest. The anchor tenant is Yahoo.
  • The Los Angeles County Data Center: This $68 million facility expected to achieve LEED certification when it is completed, according to local officials. The project has been delayed by the presence of 150 feral cats at the development site at Rancho Los Amigos South Campus in Downey.
