IntAIRieur

To learn more and take action against sources of indoor pollution, the City of Lausanne and the University of Lausanne (L’éprouvette, the Science/Society/ Unil, the Institute of Social Sciences, and the STS Lab) have partnered with Unisanté and the Renens FabLab to offer two sessions of participatory science workshops in 2025.

Two cycles of three workshops (spring and fall) brought together 41 participants from Lausanne aged 28 to 78.

 Process Overview

Invisible household pollution was measured using a sensor provided to participants for one week. After researchers from Unisanté analyzed the collected data, a discussion took place with specialists to understand the sources of household pollution and identify practical solutions.

A second phase of assessment provided an opportunity to discuss the effects of the measures implemented, public health issues, and individual and collective ways to reduce this pollution.

At the same time, a study focused on people’s understanding and perceptions of air quality and the pollutants we encounter daily in our “private” spheres. This component also explored the various practices implemented to improve air quality.

Results of the Study

Based on the workshops and the data collected by participants using sensors, as well as qualitative interviews and a questionnaire administered to participants at the end of the process, an assessment of the process can be made.
