Aeroseal – a climate-tech startup with a system to reduce energy leaks to almost zero in some buildings – has received a $67 million Series B funding round led by Breakthrough Energy Ventures and Climate Investment. Through support from several top U.S. home builders and a network of specialized HVAC dealers in the U.S. and Canada, Aeroseal has sealed 260,000 buildings (residential and commercial) since its inception. Company CEO Amit Gupta said that with the new funding, Aeroseal hopes to secure many buildings annually within three years.
According to the World Green Building Council, buildings contribute approximately 40% of the world’s carbon emissions. And nearly half of the energy used to heat or cool a building gets wasted due to leaks in its air duct system.
Aeroseal’s technology delivers sticky polymers into a building’s air ducts and envelopes to create seals where manual sealing methods cannot. And studies show homeowners can save thousands of dollars on energy bills quickly with an Aeroseal-treated house.
KEY QUOTES:
“Buildings are a critical, yet hard to decarbonize, sector, and Aeroseal’s technology is quickly making an immediate impact on emissions. The company’s solution will make it easier to electrify both new and existing buildings by significantly reducing HVAC demand and mitigating wasted energy from conventional heating and cooling systems.”
