Challenge Overview

Prize Overview

As part of the American-Made Challenges series, the Envelope Retrofit Opportunities for Building Optimization Technologies (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 overarching goal of E-ROBOT is 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. Successful competitors will provide solutions that provide significant advancements in robot technologies that will advance the energy efficiency retrofit industry and develop building envelope retrofit technologies that meet the following criteria:

  • Holistic: The solution must include mapping, retrofit, sensing, and inspection.
  • Low cost: The solution should reduce costs significantly when compared to current state-of-the-art solutions. The target for reduction in costs should be based on a 50% reduction from the baseline costs of a fully implemented solution (not just hardware, software, or labor; the complete fully implemented solution must be considered). If costs are not at the 50% level, there should be a significant energy efficiency gain achieved.
  • Minimally invasive: The solution must not require building occupants to vacate the premises or require envelope teardown or significant envelope damage.
  • Utilizes long-lasting materials: Retrofit is done with safe, nonhazardous, and durable (30+ year lifespan) materials.
  • Completes time-efficient, high-quality installations: The results of the retrofit must meet common industry quality standards and be completed in a reasonable timeframe.
  • Provides opportunities to workers: The solution enables a net positive gain in terms of the workforce by bringing high tech jobs to the industry, improving worker safety, enabling workers to be more efficient with their time, improving envelope accessibility for workers, and/or opening up new business opportunities or markets.

The E-ROBOT Prize provides a total of $5 million in funding, including $4 million in cash prizes for competitors and an additional $1 million in awards and support to network partners. 

Through this prize, the U.S. Department of Energy (DOE) will stimulate technological innovation, create new opportunities for the buildings and construction workforce, reduce building retrofit costs, create a safer and faster retrofit process, ensure consistent, high-quality installations, enhance construction retrofit productivity, and improve overall energy savings of the built environment.


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.
