By way of Data Center Knowledge is this video on IBM’s green expansion of its data center facility in Boulder, Colo. The video is of IBM’s grand opening of the expansion last month. A lot of the event, as expected, was self-congratulatory back-patting (it even includes a ribbon-cutting ceremony!) but it’s a good clip nonetheless:

- Though IBM didn’t say exactly what its power usage effectiveness (PUE) would be, it said the facility would be twice as efficient as the industry average, which is 2.5 according to the Uptime Institute. If that Boulder facility has a PUE of 1.25, that’s pretty darn good.
- Free cooling for 75% of the year using a water-side economizer
- Will use about 1 million kilowatt hours per year of wind power purchased from Xcel Energy
- Variable-speed pumps and motors in the cooling systems
- Low-sulfur diesel in the backup generators to help reduce emissions
