Aeroseal, a company whose climate technology could be of interest to commercial real estate owners and operators, announced that it received $67 million in new funding. Leading the Series-B round were Breakthrough Energy Ventures and Climate Investment.

"Buildings are a critical, yet hard to decarbonize, sector, and Aeroseal's technology is quickly making an immediate impact on emissions," said Carmichael Roberts of Breakthrough Energy Ventures. "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."

The company says that its technology "delivers sticky polymers into a building's air ducts and envelopes to create seals where manual sealing methods can't." This sounds somewhat analogous to having a flat tire on a car and using a canned inflator to get the vehicle mobile again to get to a repair shop. While no one is pumping air into a building's HVAC ductwork, there is the similarity of using a sealant to plug holes so a system can work as it's meant to.
