The CSTB has written a note for elected representatives on air confinement, available here, and an application guide, available here. CEREMA has published a regulatory guide available here. Volume 2 (page 19) is devoted to this part of the regulations.
SHOU EMA – How long should I keep the reports?2 years.
SHOU EMA – How many sensors should I use?The number of sensors is not set by law, so it’s up to each plant to decide how it wants to organize itself. The measurement lasts 2 hours per room during the heating period. For example, some facilities use a “mobile” sensor that can be moved between different rooms in a facility, or even between […]
SHOU EMA – What parts need to be analyzed?The assessment is to be applied in classrooms, activity and catering rooms, dormitories and gymnasiums. For establishments with fewer than 6 rooms, the assessment covers all these areas. For plants with more than 6 rooms, the assessment must be carried out in 50% of the rooms, with a minimum of 5 rooms. Whatever happens, we […]
SHOU EMA – Can I do the assessment myself?Yes, it can be carried out independently, either by technical staff or by users of the premises (teachers, supervisors, etc.).
SHOU EMA – When should I carry out the first assessment?The assessment is to be carried out for the first time in 2024, and then every year during the heating period.
SHOU EMA – Where can I find detailed information on the regulations?Indoor air quality monitoring regulations are imposed by the French Environment Code and Decree no. 2022-1689 of December 27, 2022. The text is available here. To provide a clearer picture, CEREMA has published a guide to the implementation of regulatory monitoring. You can consult this guide here .
SHOU EMA – Is regulatory compliance possible on your own?Yes, with the exception of the work phases, all regulations can be carried out independently.
SHOU EMA – What do these regulations require?An annual Assessment of Ventilation Equipment (EMA) for buildings, including direct-reading measurements of carbon dioxide concentrations in indoor air. An IAQ self-diagnosis questionnaire to assess practices and associated risks, and identify applicable best practices. This questionnaire must be updated every 4 years. A pollutant measurement campaign to be carried out when work is carried out […]
SHOU EMA – How long have regulations existed? Which establishments are concerned?Indoor air quality regulations apply to collective establishments that cater for the most vulnerable populations, i.e. minors and the elderly. This applies to day-care centers, schools, middle schools and high schools, as well as leisure centers, juvenile prisons and nursing homes. This regulation came into force in 2015, but a major change was made very […]
VOCs – How to interpret measurements?Volatile organic compounds (VOCs) These compounds are emitted by paints, glues and other solvents. If the concentration is too high, ventilate as soon as possible.
CO2 – How to interpret the measurements?NEXELEC sensors can measure CO2, depending on the model. Depending on WHO and ANSES regulations, thresholds may differ from one country to another. The values set out below are valid for ERP (Etablissements Recevant du Public) in France. Carbon dioxide (CO2) CO2 is a good indicator of Indoor Air Quality. If the ppm level is […]
