The two-story building features three truck bays, two fire poles, dispatch area, contamination room, and gear storage.

The city of Rochester, Minn., home of the famed Mayo Clinic, is going big on geothermal networks. The city is constructing Thermal Energy Networks (TENs) that consist of ambient pipe loops connecting multiple buildings and delivering thermal heating and cooling energy via water-source heat pumps.
