1.What are the existing air quality regulations in force?

Since the decree resulting from the Grenelle II law of 17 August 2015, there is a regulatory obligation to monitor the quality of indoor air in establishments that receive the public, with a schedule that began on 1 January 2018 in establishments for young children. This will be followed by an obligation for secondary schools in 2021, and then for all establishments (museums, hospitals, leisure centres, etc.) from 2023 onwards.

2.Why should we pay attention to the quality of our indoor air?

We spend nearly 80% of our time in enclosed spaces, whether private (apartments, houses, work…) or public (schools, administrations, leisure facilities…). For a long time ignored, the issue of indoor air quality has since been invested in understanding the stakes and areas for improvement. A 2006 study made public by the Indoor Air Quality Observatory (OQAI) has, for the first time, enabled a large-scale inventory to be carried out in France, highlighting the existing pollution inside buildings. Although there are many exchanges of flows with the outside air, closed environments have many specific characteristics. The quality of indoor air is regularly worse than that of an open space. This continuous pollution can be explained by the products and objects of our daily life that emit many substances, by our activities and practices and by the trap that insulation constitutes if the room is poorly ventilated.

A more recent study dated 23 June 2014 conducted by the National Agency for Food, Environmental and Occupational Health Safety (Anses) and the Centre Scientifique et Technique du B�timent (CSTB) highlighted the socio-economic cost of indoor air pollution. The study focused on six of the main pollutants whose health effects are known to be known: benzene, trichloroethylene, radon, carbon monoxide, particles and “environmental tobacco smoke” (passive smoking). Its results reveal that domestic pollution causes nearly 20,000 deaths a year and costs more than 19 billion euros annually. These figures are all the more noteworthy because they do not take into account important pollutants such as formaldehyde, co-exposure to certain substances or certain pathologies linked to indoor air pollutants.

On the occasion of the Assises nationales de la qualit� de l’air 2013, the Ministry of Ecology, Sustainable Development and Energy and the Ministry of Social Affairs and Health launched the Indoor Air Quality Action Plan. This action plan comprises 26 actions and will be designed to integrate the third National Health and Environment Plan (PNSE3 – 2015-2019). The reduction of indoor air pollution requires knowledge of the sources of pollutants and the means to control it, which appear in particular in the PNSE3.
