Topic #: CW26-T04 · Branch: DOE · Status: Open
BTO seeks innovative proposals that can lower both the up-front cost of new energy-saving technologies and operational energy use for consumers. Topics of interest include air and water heating, ventilation, air conditioning, and refrigeration systems; technologies that optimize building operations, including technologies that enable energy system integration; and technologies for improving building envelopes in new and existing buildings and saving costs across all sectors and regions.

This button copies the full topic as plain text: the work, the dates, the apply steps, and the readiness list. Paste it into the AI you already use. Ask it if the work fits your firm, what you are missing, and what to skip.
This call starts with a short pitch, not a full proposal. Use the copy to judge the fit and shape the pitch. The call follows SBA policy: no limit on AI help, and no disclosure is required. Your firm signs the pitch and answers for every claim in it.
The first step is a short pitch, on the ConnectWerx site.
ApplySelect Apply. The official call page opens on the ConnectWerx site. The first step is a short pitch in the ATI portal. Full proposals are by invitation only.

Eligibility comes first. SBIR and STTR awards go to small businesses: for-profit, based in the United States, 500 or fewer employees counting every domestic and foreign affiliate, and at least 51 percent owned and controlled by U.S. citizens or permanent residents. A company owned by a large parent usually cannot apply on its own. It can take part as a subcontractor under an eligible small business.
An ATI portal account is set up for the person who will submit the pitch. Pitches go in through the portal, and the account takes time to set up. To pitch, the portal account is what you need.
If your pitch is invited, the full application needs SAM.gov entity registration active. Start it now: a new registration takes 10 or more business days to become active.
If your pitch is invited, the full application needs the SBA Company Registry complete. You get a SBC Control ID. Start it now: identity checks cannot be rushed.
The first step is a pitch: 4 narrative questions, 3 short-answer questions, and 7 structured selection questions, due by the date above at 2:00 p.m. Eastern. Full proposals are by invitation only. Plan to submit the pitch early.

BTO seeks innovative proposals that can lower both the up-front cost of new energy-saving technologies and operational energy use for consumers. Topics of interest include air and water heating, ventilation, air conditioning, and refrigeration systems; technologies that optimize building operations, including technologies that enable energy system integration; and technologies for improving building envelopes in new and existing buildings and saving costs across all sectors and regions.
Areas of Interest While any topics that address the topic are welcome, specific areas of interest include:
a. Technologies that simplify dual-fuel heating, ventilation, and air conditioning (HVAC): including on-board, building-level, and utility-level controls. The technologies should streamline system optimization, improve fuel switchover logic, enhance energy system flexibility, and reduce commissioning and maintenance burden. Complete low-cost, dual-fuel HVAC systems could be responsive to this area.
b. Control and modeling technologies that use super intelligence (SI) or machine learning to save time and money for customers: The technologies should allow consumers to export data and leverage third-party platforms, making their data easier to use.
Not of Interest Proposals out of scope: Software that simply aggregates third party data or displays it (e.g. an analytic or dashboard application) is out of scope, as are SI-enabled information systems that do not have integrated controls or data collection.
