The American-Made Buildings Prize: Envelope Retrofit Opportunities for Building Optimization Technologies (E-ROBOT) is designed to catalyze the development of minimally invasive, low-cost, and holistic building envelope retrofit solutions that make retrofits easier, faster, safer, and more accessible for workers.



As part of the American-Made Challenges series, the E-ROBOT Prize unites the world’s best-in-class research base with the unparalleled entrepreneurial support system of the American-Made Network. Consisting of pioneering makerspaces, dozens of energy incubators, universities, and 17 U.S. Department of Energy (DOE) national laboratories, the Network is primed to create a sweeping portfolio of innovations to demonstrate the promise of advanced robotics for building envelope retrofits.

Advancements in robotics allow workers to reach places or perform activities that were previously impossible. For example , robots can safely enter small spaces and cavities, such as ductwork, to perform air-sealing or other efficiency activities . Robots can complement and support the existing workforce by creating new employment and business opportunities while also helping to ensure quality and consistency when installing energy efficiency measures.

The Prize Structure

The E-ROBOT Prize is made up of two phases that will fast-track efforts to identify, develop, and validate disruptive solutions to meet building industry needs. Each phase will include a contest period when participants will work to rapidly advance their solutions. DOE invites anyone, individually or as a team, to compete to transform a conceptual solution into product reality.
