Efficient control of ventilation systems needs information on indoor air pollutant concentration. But most of the time, the pollutant concentration is not measured. However, outdoor air pollution forecast models are becoming operational and a relation between outdoor and indoor pollutant concentration may be used to predict pollutant concentration peaks and to infer recommendations to reduce its value . A prediction model of the outdoor/indoor air pollutant transfer, based on experimental data, was obtained using multiple linear regression. The measurements were achieved in a primary school classroom in the coastal region of La Rochelle, France. The measured parameters are the outdoor and indoor concentrations, the indoor temperature and humidity, window openings, number of photocopies and the number of pupils in the classroom. Models for NO, N02 and 03 outdoor/indoor relation are achieved and tested.
