365 Main, a data center builder and operator whose customers\ninclude Craigslist and Red Envelope, recently announced plans to\nimplement the U.S. Green Building Council\u2019s Leadership in Energy and Environmental Design\n(LEED) standards for all of its future data centers. The first\nsuch data center, located in Newark, Calif., is scheduled to\nbegin operations in Q4 of 2007. Companies in the new building will\nlease 5,000 to 30,000 square feet \u201cpods\u201d in which to run\ntheir data center operations. A financial service institution,\nbased in the Bay Area, has already committed to space in the\nfacility, and \u201cseveral other high-tech and hosting companies\nare in final negotiations for space,\u201d says Miles Kelly, 365\nMain\u2019s vice president of corporate strategy.\n\n365 Main\u2019s announcement is an example of a growing trend\ntoward LEED-certified data centers as companies attempt to improve\noverall corporate sustainability, and cut their energy costs by\nimproving efficiency. The Washington, D.C.-based mortgage company,\nFannie Mae, for instance, completed the first-ever LEED-certified\ndata center in 2005. Highmark, a health insurance company based\nPennsylvania, also completed an 87,000-square-foot green facility\nthat same year.365 Main\u2019s Kelly says that, in addition to the adoption of\nLEED standards for all new data centers, the company will address\nincreasing concerns about energy consumption by retrofitting\nexisting facilities, such as its San Francisco data center, which\nis home to Craigslist IT. Retrofitting, however, isn\u2019t always\neasy. \u201cMany of the items on the LEED checklist, such as using\nrecycled or locally sourced construction materials, are done during\ninitial construction; I can\u2019t swap out walls or beams,\u201d\nsays Kelly. But there are certainly other ways to improve\nefficiency, and Kelly plans to implement those methods in 365\nMain\u2019s existing facilities. \u201cLow-hanging fruit, like\nlighting, can be made more efficient through power controls.\nEfficient irrigation systems will also be applied.\u201dDuring CIO.com\u2019s recent Green IT roundtable, Jonathan Koomey, staff scientist at Lawrence\nBerkeley National Laboratory, said that the metrics required for\ndata centers are so different from those required in commercial\nbuildings that employing LEED in the data center often\ndoesn\u2019t do enough to improve efficiency. For example, Koomey\nhas been working with the EPA on metrics for low-cost \u201cvolume servers and infrastructure, which\ncurrently aren\u2019t incorporated into LEED standards. In the\nsame discussion, Kevin Klustner, CEO of Verdiem, a developer of\npower management software for PCs, pointed out that LEED\ncertification specifically for data centers would make sense, and\nsuggested that the Green Grid, a consortium of technology companies\naimed at improving data center efficiency, work with the Green\nBuilding Council on developing such standards. Marv Adams, CIO of\nCitiBank, who also participated in the discussion, said that\nregardless of that, there are certain LEED criteria that\nundoubtedly make sense in the data center. Adams\u2019\nsuggestions include optimizing the IT equipment and heating,\nventilation, and air conditioning layout to provide user\nflexibility and necessary cooling, designing the building to limit\nheat gain (this can be done through a \u201cgreen\u201d roof\n\u201cmeaning the top of the building is covered with\nvegetation,\u201d or incorporating trees into the landscape),\npurchasing from local vendors and reducing water consumption.\nAdding to that list, Kelly says that controls\u2014such as motion\nsensors\u2014that reduce the draw on lightbulbs can improve lighting\nefficiency. He also suggests using recycled materials during\nconstruction, and implementing recycling programs for construction\nwaste like metal and cement.
