Establishments receiving the public and Education

The monitoring of air quality is regulatory since 2018 in certain establishments receiving the public such as nurseries, schools, middle schools, high schools and, from 2023, universities. Indeed, studies conducted in the early 2010s have shown that the indoor air in these institutions can be up to 10 times more polluted than the outdoor air. Poor air quality can have serious consequences: decreased concentration and cognitive abilities, development of chronic diseases such as asthma, allergies, respiratory tract irritation, chronic fatigue. The managers of these establishments have objectives of results to guarantee a healthy air for the occupants. Today, a new risk is emerging that has been little taken into account until now: the sanitary risk.

PHOSPHORIS offers personalized support to building owners and managers to take into account air quality throughout the life of the building: construction, renovation, operation. We find solutions to reach the air quality objectives on the regulatory parameters: Formaldehyde, Benzene, Carbon dioxide, Tetrachloroethylene, Radon.
