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

Northglenn, Colo., a Denver suburb, has opened the new Northglenn City Hall—a net zero, fully electric building with a mass timber structure. The 32,600-sf, $33.7 million building houses 60 city staffers. Designed by Anderson Mason Dale Architects, Northglenn City Hall is set to become the first municipal building in Colorado, and one of the first in the country, to achieve the Core certification: a green building rating system overseen by the International Living Future Institute.

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.

ENSO, a U.K.-based company that makes tires for electric vehicles, has announced plans to build the first carbon-neutral tire factory in the U.S. The $500 million ENSO technology campus will be powered entirely by renewable energy. The first-of-its-kind tire factory aims to be carbon neutral without purchased offsets, using carbon-neutral raw materials and building materials. 

The standards for energy-efficient construction and design have been raised. Due to the development of advanced low-e coatings for the interior surface and vacuum insulating technologies, architects now have more choices to improve U-values wherever enhanced thermal performance is needed to create eco-friendly spaces. These options can double or even triple thermal performance, resulting in annual energy savings and a positive return on carbon.

Artificial intelligence could help U.S. buildings to significantly reduce energy consumption and carbon emissions, according to a paper by researchers at the Lawrence Berkeley National Laboratory.

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.

Zurich Soft Robotics says Solskin can reduce building energy consumption by up to 80% while producing up to 40% more electricity than comparable façade systems.
