300 Million-Year-Old Limestone Houses Ultra Efficient Data Center 22 Stories Underground

data center cave


A data center in western Pennsylvania, built inside an old limestone mine, is using the benefits of a very cool location to experiment in the use of geothermal environmental conditions for energy efficiency. Their researchers are trying to find out if putting data centers deep underground will be an ideal and energy efficient place for them.

This data center doesn't rely on a raised floor like most data centers at surface level. Instead, they use the cool from the limestone walls - which can absorb 1.5 BTUs per square foot - and vents attached to ceiling ducts. The server racks trap electrical heat and force it up through ceiling tiles, where the limestone absorbs the heat naturally. In addition, the HVAC system uses the ancient environmental features of the caves, pulling water from a several hundred-acre underground lake for cooling.

Computerworld states, "By setting the room's return air temperature to 75 degrees, Iron Mountain cut energy consumption for cooling by between 10% and 15% compared with the company's traditional data centers."

    Solar energy has bcmoee increasingly important to industrially developed countries as the effects of fossil fuels are linked to global warming and pollution. A company that offers a vital product, energy transformers, to the renewable energy sector is Pacific Crest Transformers. Pacific Crest Transformers manufactures energy efficient liquid-filled distribution transformers for a wide range of industry verticals.
