When most people think of green investing, they think of solar panels or electric cars. Some savvy investors, however, realize the greatest potential for helping the environment and getting a good return on investment comes from the HVAC industry. One of these investors, Breakthrough Energy Ventures, recently led a funding round for Aeroseal LLC that raised $22 million. Energy Impact Partners and Building Ventures also participated.
The company helps contractors seal ducts using an aerosolized material. They seal off the ducts and spray this material in, and it covers any leaks.
