Oqai

The Observatoire de la qualité des environnements intérieurs (OQEI) is a French reference observatory focused on the quality of indoor environments. Drawing on the joint expertise of Anses and CSTB, it provides scientific resources, reliable data and practical guidance to help improve places where people live and spend time. Its work supports public policy and aims to protect occupants’ health and well-being amid climate change, energy-efficiency efforts and changing social practices.

The OQEI examines indoor air quality, acoustic, visual and thermal comfort, and energy consumption across settings including homes, schools, healthcare facilities and energy-efficient buildings. Through campaigns and studies, it investigates topics such as indoor pollution, pollutant exposure and household activities, and publishes reports, statistics, indicators and other research findings. The observatory also shares educational information about pollution sources, health effects and ways to improve indoor air, including ventilation and reducing pollutants. Its website features expert events, publications and practical resources, while committees involving public bodies, agencies and stakeholders help guide and strengthen its work.
