Indoor Air Quality analysis needs at first an accurate prediction of indoor pollutant concentration levels. However, most of pollutant concentration prediction models consider the pollutants as passive elements. Our study introduces the more common gas-phase chemical reactions occurring in indoor spaces. We developed a model taking into account more than 20 different reactions influencing the concentration level prediction of NOx compounds, ozone, carbon monoxide and sulphur dioxide from the knowledge acquired in the field of tropospheric chemistry. As the model was designed to assess the dynamic variations of indoor solar actinic irradiance, it particularly can deal with the photochemical dissociation reaction of N02. A case study using real outdoor pollution and climatic data enables us to show the large influence of these homogeneous processes on the indoor pollutant concentration prediction, and demonstrates the necessity of taking them into account in the frame of a healthy air quality analysis.
