Computer Heat Warms Building

Associated Press

A new five-story building here is heated entirely by warmth recovered from computers, lights and bodies--despite occasional sub-zero winter weather, reports Energy User News.

According to the publication, energy-efficient fan and pump motors, use of the building's rooftop cooling tower for sprint and fall cooling and new insulation also contribute to a 50% drop on energy use, compared to similar buildings in the Grand Rapids area.
