IBM says it has flipped the switch on what it has dubbed <A HREF="http://blogs.zdnet.com/green/?p=1139&tag=nl.e622">the "greenest" datacenter in North America.</A> The 115,000-square-foot facility is sited in Boulder and was made out of an existing office building. Approximately 65 percent of the materials from the original facility were recycled and about 25 percent of the "new" materials used in the retrofit contained recycled products. IBM snagged training incentives from the state, some investment credits from the city and some rebates from Xcel Energy for the work it did on the project.
