Incubating Market-Propelled Entrepreneurial-Mindset at the Labs and Beyond

IMPEL is a Department of Energy tech-to-market program focused on building technologies, funded by the Building Technologies Office and implemented by Lawrence Berkeley National Laboratory.

Our program helps early-stage individuals from business, academia, and DOE’s national labs translate the premise and promise of their technology into the language of business, boosting their chances of bringing it to market. These individuals–or as we call them, IMPEL Innovators–have a passion for the building lifecycle (design, construction, operations, and circular technologies) and for energy technologies that integrate with buildings (onsite renewables or grid integration incorporating electrification, energy storage, and electric vehicle charging). The buildings sector has been notoriously challenging for bringing tech-to-market, where many new projects or businesses fall victim to the notorious ‘valleys of death’.

IMPEL has a strong theory of change: Support technological transformations for net zero built infrastructure, that promotes equitable wellness and resilience for all.

Our Innovators have projects that drive:

Meet our 2023 Innovator cohort

From attractive and efficient solar roofing tiles equipped with batteries for energy storage; to hemp-based, fire-resistant cladding for homes in wildfire zones; to modular interiors designed to transform vacant buildings into comfortable, affordable apartments–our 2023 cohort is bringing innovative, climate-smart building technologies to market. Learn more about the cohort on our 2023 Innovators page.

Innovators reach new heights after IMPEL. 

After going through our program cycle, Innovators find themselves achieving new successes and progressing in their tech-to-market journeys.

Hear IMPEL Program Director Reshma Singh talk about the IMPEL engine that accelerates climate tech in buildings and energy by recruiting and fostering a dynamic Innovator community, mentoring them to develop strong entrepreneurial skill sets, and enabling access to powerful public and private tech-to-market pipelines.

IMPEL Provides Coaching & Opportunities

Innovators begin their IMPEL journey in intensive workshops, where our Expert Coaches provide a deeper understanding of market factors that help Innovators develop a better project roadmap. Following participation in the IMPEL workshops, Innovators will be eligible for additional opportunities to receive technical training through the Carbon Tools Webinar, business plan development through a series of Business Seminars, and additional pitching and mentoring opportunities through program partners at the U.S. Department of Energy and Greentown Labs.


With the intensive guidance of IMPEL Expert Coaches, Innovators refine and practice pitches for critical stakeholders. Activities include real-time tailored exercises, on-video training, and live one-on-one coaching with professional critique

Mentoring and Office Hours

IMPEL Innovators meet individually with the program's Executive Team and Mentors for an opportunity to apply learnings from the workshop, and receive specific, actionable feedback about their projects.

Carbon Tools 

All Innovators will be invited to a Carbon Tools webinar presented by scientists and researchers to introduce tools for estimating the embodied and operational energy and carbon impacts of building energy technologies and materials.

Reverse Pitch

Officials from the National Laboratory System will present licensable intellectual property related to building energy use. Innovators will also hear from  private investors, incubators, and public-sector grant programs on what they are looking for. 

Business Seminars

After participating in an IMPEL workshop, downselected Innovators will participate in three business seminars for personalized coaching to develop an initial business plan and customized strategies to address  Competition, Product-market fit, Go-to-market strategy, Pricing and Revenue, and Organization.


Standout Innovators from each IMPEL workshop will be selected to pitch at the 2023 BTO National Showcase event, the 2023 Innovative Housing Showcase by the Department of Housing and Urban Development, or at Pitch events conducted by partnering incubator and accelerator organizations.

Visit the IMPEL Pipelines page for more information about each of these pillars of IMPEL programming.

IMPEL Connects Innovators to Experts

The IMPEL Executive Team at Lawrence Berkeley National Lab supports Innovators' journeys through every step of the program, while connecting them to Expert Coaches, Incubators, Mentors, and a wider network within the building technology space. 

Read more below about the types of experts that IMPEL offers.

Expert Coaches

IMPEL Coaches provide dynamic guidance during the one-day workshops to help Innovators refine and practice verbal pitches to communicate their technology or idea clearly, succinctly, and compellingly to critical stakeholders. Our coaches are field experts: skilled entrepreneurs who have raised multi-million dollar funds, judged startup pitches, coached technologists towards successful commercialization.

Meet our Coaches


IMPEL has partnered with Greentown Labs to provide real pitching opportunities and connections to a broader pool of mentors, investors, and other innovators in climate-tech. They help Innovators engage with the private sector, gain fully-funded access to national pitch events, and accelerators. 

Learn more about our Partners


IMPEL Mentors represent investors from boutique and impact funds to financial giants, potential demonstration partners from major universities, state energy offices, and federal entities including the General Services Administration and the Department of Defense, major corporate ventures, and subject matter experts from national labs.
