The U.S. General Services Administration’s (GSA) Green Proving Ground (GPG) program, in collaboration with the U.S. Department of Energy (DOE), has selected six innovative building technologies for evaluation in GSA’s inventory.

The GPG program leverages GSA’s extensive real estate portfolio to evaluate innovative building technologies in real-world settings. Evaluation results enable GSA to make sound investment decisions in next-generation building technologies. An additional three technologies will be tested through DOE’s commercial building partners.

The technologies were chosen in response to GSA’s most recent Request for Information seeking technologies for net-zero carbon buildings. The evaluations are intended to validate the technical and operational characteristics of the technologies and their potential for future deployment.

“By using GSA-controlled facilities as a proving ground for innovative clean energy technologies, we can help spur new industries in areas such as energy-saving windows, smart pumps, microgrids, and more,” said GSA Administrator Robin Carnahan. “This demonstrates how our facilities can serve as a catalyst for American innovation that can create good-paying, clean energy jobs, save money for taxpayers and leave our kids a healthier planet.”

EndoTherm was selected based on the fact that closed-loop heating, ventilation, and air conditioning (HVAC) systems rely on water to transfer heat energy throughout a building. EndoTherm hydronic additive promises to improve the heat transfer properties of water to reduce energy use in closed-loop HVAC systems.

Alongside EndoTherm the following technologies were also selected:

  • C02-Based Heat Pump, Dalrada (Escondido, CA)
  • Solar PV Tracking, Rocking Solar (Monroe, OH)
  • Non-Metalized Window Film, 3M (St. Paul, MN) and NGS (Atlanta, GA)

The program also selected two technologies aimed at unlocking the value of electric vehicle batteries to not only power vehicles, but to interact dynamically with a building’s electric load and the local electric grid.

  • EV Charge Management, WeaveGrid (San Francisco, CA)
  • Bi-directional EV Charging, Fermata Energy (Charlottesville, VA)

More information on the above technologies and other ongoing evaluations can be found at GPG’s Ongoing Assessments webpage.
