The Advanced Research Projects Agency - Energy (ARPA-E) is issuing a Request for Information (RFI) focused on the development of highly insulating building enclosures, specifically targeting R-10 rated windows and R-50 rated walls for both residential and commercial applications. This initiative aims to gather insights from various stakeholders, including manufacturers and research institutions, to inform the potential formulation of future programs that enhance thermal performance and reduce energy consumption in buildings, which accounted for approximately 12% of national energy use in 2022. Interested parties are encouraged to submit their feedback regarding innovative technologies, production processes, and market adoption challenges by June 7, 2024, at 5:00 p.m. Eastern Time, via email to ARPA-E-RFI@hq.doe.gov. For more information, please refer to the full RFI available at https://arpa-e-foa.energy.gov.
