Discusses oxygen requirements and moisture emission of individuals and generation of CO2, odours, and aerosols in inhabited rooms. Treats calculation of hygienically necessary air flow rates. Notes characteristics of continuous andintermittent ventilation, whereby additional outside air is discharged into a room at set intervals when continuous airflow rate falls below hygiene requirements. Compares hygienically adequate, continuous ventilation with intermittent ventilation by calculating hygienically-necessary outside air flowrate using a mathematical mode.
