I e mailed the company a few weeks back and was advised that they can't disclose any details as they are under NDA with the GSA which is a pity but understandable.

Replied to post over two years ago- apparently it was all B.S.

Apparently the guy running the program quit.


Green Proving Ground Program Selects Innovative Technologies that Enable Transition to Net-Zero Carbon
May 16, 2022
Selections include GPG’s first electric vehicle supply equipment technologies

WASHINGTON, DC — 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, including the program’s first selections of electric vehicle (EV) charging technology. 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 American-made 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.”

C02-Based Heat Pump, Dalrada (Escondido, CA) – Decarbonizing heating is key to achieving Net-Zero. This combustion-free heat pump promises to increase heating and cooling efficiency by capturing and reusing thermal energy while reducing global warming potential. Using carbon dioxide as the refrigerant, this heat pump can deliver cooling down to -22°F and heating up to 250°F.
