【 摘 要 】

The article presents measurements carried out in an office room using metabolically generated carbon dioxide. The measurements were conducted using concentration decay gas tracer method. Increase of the concentration of CO2 in the room occupied by workers allowed for evaluation of internal air quality and thermal work conditions. Analysis of the CO2 concentration decay conditions after leaving the space by users was used to determine the efficiency of ventilation system and room envelope airtightness. The obtained results were used to calculate specific airflow rate of natural ventilation system being used in the analysed room.
