In order to reduce the high energy losses in air ducts, the climate fund Breakthrough Energy Ventures, supported by Bill Gates, has invested 22 million US dollars in Aeroseal.

Buildings account for around 40 % of total energy consumption in the USA and Europe. A good 50 % is consumed by heating and cooling, and another “energy destroyer” is air handling and air duct systems, which lose up to 30 % of the transported air through leaks, holes and poor connections.

The investment makes it clear that improving the energy efficiency of buildings is one of the most effective ways to reduce greenhouse gas emissions and combat global warming.
