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

Promoting equitable wellness and resilience in the built environment through commercial advancement of net zero technologies

IMPEL is a technology-to-market program for building technologies led by Lawrence Berkeley National Laboratory and funded by the U.S. Department of Energy's Building Technologies Office.

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. 

Reach new heights with IMPEL

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’.   Post-IMPEL, our Innovators achieve new successes and progress in their commercialization journeys.

IMPEL Provides Foundational Training and Pipeline Opportunities

Our 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). 

All IMPEL Innovators receive:

Selected Innovators will also be offered exclusive opportunities for further training and opportunities, including:

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. 

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.
