The U.S. Department of State’s Bureau of Overseas Buildings Operations (OBO) has announced that the first large-tonnage magnetic levitation (maglev) bearing chiller in Europe came on-line today at the United States Mission to the United Nations in Geneva, Switzerland.

This new, environmentally-friendly U.S. demonstration technology is the long awaited commercialization of a scientific breakthrough in physics and electronics: a precise rotating, magnetic levitation bearing. The maglev bearing technology provides a virtually friction-free, oil-free motor and compressor, all but eliminating bearing heat, wear, and tear.

The maglev technology is expected to reduce the energy required to air-condition the U.S. Mission by up to 30 percent, and will reduce the Mission’s carbon dioxide output by over 25 metric tons per year.

This project is the fourth significant OBO “green” investment at the U.S. Mission in Geneva over the past five years. In addition to the maglev chillers, OBO’s energy conservation retrofit investments are:

  • High efficiency lighting
  • A high efficiency, low emission, heating boiler
  • A solar electric, photovoltaic power generation plant

This maglev technology project is OBO’s next step in showcasing U.S. energy conservation and sustainability technology. OBO will implement this U.S. demonstration technology at additional diplomatic posts overseas in the future.
