Questions Regarding Funding Opportunity Announcements

Please contact the email address for questions regarding Funding Opportunity Announcements. Upon the issuance of a FOA, only the Contracting Officer may communicate with Applicants. ARPA-E personnel and our support contractors are prohibited from communicating (in writing or otherwise) with Applicants regarding the FOA. This “quiet period” remains in effect until ARPA-E’s public announcement of its project selections.

ARPA-E will not pre-assess an Applicant’s proposal. Prospective Applicants must review the technical requirements of the FOA and independently determine whether their proposed concept warrants a submission.

DE-FOA-0000289: Building Energy Efficiency Through Innovative Thermodevices (BEETIT)

ARPA-E seeks to develop energy efficient cooling technologies and air conditioners (AC) for buildings to save energy and reduce GHG emissions from: (a) primary energy consumption due to space cooling and (b) refrigerants used in vapor compression systems.  ARPA-E seeks innovative research and development approaches to increase energy efficiency and reduce GHG emissions due to cooling of buildings in the following areas: 1) cooling systems that use refrigerants with low global warming potential; 2) energy efficient air conditioning (AC) systems for warm and humid climates with an increased coefficient of performance (COP); and 3) vapor compression AC systems for hot climates for re-circulating air loads with an increased COP.  The unique challenge for the U.S. market is to develop technologies that can be retrofitted into current cooling systems.  For developing economies, there is a large market for new cooling technologies.  The development of these technologies will reduce GHG emissions and significantly increase U.S. technological lead in rapidly emerging clean energy industries.
