5 years of Game-changing technologies

IMPEL, a Department of Energy tech-to-market program that unites innovators with researchers, investors, and business experts — is celebrating five years of advancing next-generation building decarbonization technologies to market. 

From 3D-printed thermal energy storage, to drones that use machine learning to scan entire neighborhoods’ worth of buildings for air leaks, to quiet wind turbines that can be installed in tight spaces, great early-stage ideas are moving toward the market. Innovators get the mentorship, coaching, and support they need to turn promising concepts into concrete products.

$100M+ raised

25 U.S. states/territories represented

167 awards, grants, prizes, and pilots

~180 green jobs created

Buildings account for about 35% of the nation’s carbon emissions, and innovative building technologies are an increasingly essential element in effective climate action. 

That’s behind initiatives like the international Buildings Breakthrough partnership, which pledges near-zero emissions and climate-resilient structures by 2030. IMPEL will continue to advance game-changing technologies that will help us meet that goal.
