In the context of climate change, and development of energy efficiency policies such as Eco-design of energy using products, EPBD, Energy Efficiency directives, ventilation systems are expected to become more energy efficient and the energy needed to filter the air reduced to a minimum. Building are more and more insulated creating confined indoor environment known for long to have a detrimental effect on health and productivity, if not balanced by appropriate ventilation.
Every year, more than 300 000 Europeans die prematurely from the health impact of air pollution (CAFE project). According to DG SANCO’s Envie Report published in 2008, about 2 million days of healthy life are lost each year as a consequence of indoor air pollution.
We spend more than 80% of our time indoors. Indoor air pollution not only results from emission of chemicals from building materials, furniture, electronic devices, indoor human activities such as Hobbies, DIY, cooking and heating but results as well from outdoor air pollution infiltration in our buildings. As a consequence, Indoor air can be up to 50 times more polluted than outdoor.
