The International Energy Agency’s (IEA) June 2016 report on Energy and Air pollution identifies air pollution as the world’s no. 4 threat to human health. The report underlines that most of the roots and cures are to be found in the energy sector. As a consequence, the building sector which represents 40% of all energy consumption and 36% of CO2 emissions should be the first point of action. It is widely known that building insulation can bring significant energy savings; CO2 reductions; higher energy security; higher employment and increased competitiveness. But, did you also know that building insulation, through the reduced use of energy in domestic heating and cooling limits related outdoor air pollution and thus enables economic, mostly health care related, savings of ≥6.65 billion € /year and an annual EU gain of 70,000 Life Years resulting from the diminished emissions.
