Aeroseal, a climate tech company shrinking carbon emissions from residential and commercial buildings, recently announced it has raised $22 million in funding. The Series A round was led by Breakthrough Energy Ventures (BEV) with participation from Energy Impact Partners and Building Ventures.
Homes and buildings consume 40% of the nation’s energy, but an average of 30% of this energy is wasted, according to the Department of Energy. In large part, this energy is wasted through small leaks in heating and cooling ductwork, as well as the building envelope separating the interior and exterior of every structure.
The ducts and walls in buildings are inadequately sealed by manual solutions. Aeroseal’s technologies, HomeSeal Connect and AeroBarrier Connect, inject a fog of sealant particles into these pressurized spaces. These particles safely seal leaks as big as 5/8” and as small as a human hair. Software tracks the entire process, creating a certificate of completion showing before and after leakage.
As the world reaches an inflection point around climate change, this funding will help Aeroseal accelerate its mission: enabling homes and building to reach net zero emissions. To do this, Aeroseal will scale its R&D, marketing team and increase support of its dealer network.
“This funding ensures our team can reach its goal of shrinking carbon emissions by 1 gigaton,” says Amit Gupta, CEO of Aeroseal. “We are doubling our focus on innovation to make our technologies even easier and more cost-effective to deploy throughout the world. Whether we are enabling net-zero home construction or improving energy efficiency on existing buildings, Aeroseal can help any building reduce its carbon footprint.”
The company’s 100 employees in Dayton, Ohio, serve contractors and builders who are sealing ducts and walls around the globe in everything from homes, hospitals and schools to government facilities, hotels and offices. During the pandemic, the importance of more comfortable spaces with cleaner, healthier air became more important than ever.
“Building emissions are a significant contributor to climate change globally, and a problem that the BEV team is actively working to solve,” says Carmichael Roberts, Breakthrough Energy Ventures. “Aeroseal’s technology addresses a challenge found in every building: energy waste caused by undetectable and unreachable leaks."
Energy Impact Partners is investing in Aeroseal because utilities are looking for innovative, cost-effective energy efficiency solutions that enable them to support their customers’ efforts to manage their energy spend and carbon footprint.
“Aeroseal can deliver an energy efficiency solution that can be rapidly deployed at scale for commercial and residential buildings,” says Sam Bursten, Vice President at Energy Impact Partners. "We are confident that Aeroseal’s solution will play a major role in creating sustainable, safe, and healthier homes and workplaces.”
