Northglenn, a Denver suburb, opens a net zero, all-electric city hall with a mass timber structure

A U.S. Dept. of Energy document discusses the benefits and challenges of thermal energy storage for commercial buildings. The document explains how the various types of thermal energy storage technologies work, where their installation is most beneficial, and some practical considerations around installations.

Charlotte, N.C.’s new Fire Station #30 will be one of the country’s first all-electric fire stations, using no outside energy sources other than diesel fuel for one or two of the fire trucks. Multiple energy sources will power the station, including solar roof panels and geothermal wells. 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.
