The aim of this study is to analyse the impact of volatile organic compounds emissions from asolid flooring material on the concentration field in a ventilated room. A field study has beenconducted in the CSTB experimental house MARIA. Measurements were performed in a testroom recently equipped with a flooring material made of pine wood and under controlledventilation conditions. a-Pinene was selected as tracer from flooring VOC emissions. Velocityand temperature fields are measured in different points of the room. As the experiment isconducted in a room of a real house, thermal conditions cannot be imposed. However, indoor wallsurface temperatures are measured in order to control the stability of boundary conditions duringthe experiment.a-Pinene concentrations were measured in the test room and in the extract flow. The emissionsof the solid flooring material can be calculated from those measurements considering a-pinene asa non reactive compound and steady state conditions.Experiments were conducted for different air flow rates controlled with a mechanical extractionplaced on the door of the room.Measured a-pinene concentrations and air velocities have been compared with steady statecomputional fluid dynamic (CFD) calculation fields. They show a good agreement.We observed a relatively homogeneous VOC concentration field in the room except in the airflow supply and near the flooring surface where stratification of the tracer occurs.
