Impact of ventilation rates on SBS symptoms and productivity in offices.

Auteurs : WARGOCKI P., FANGER P. O.

Résumé

Perceived air quality, Sick Building Syndrome (SBS) symptoms and productivity were studied in a normally furnished office space ventilated with an outdoor air flow of 3, 10 and 30 L/s per person, while all other environmental parameters remained unchanged. Ventilation was provided by an axial fan mounted in the window to avoid any potential pollution sources in a traditional HVAC-system, and almost perfect mixing of air was provided at an air velocity below 0.2 m/s in the occupied zone. At each ventilation rate, 30 female subjects occupied the office for 4.6 hours in the afternoon, six subjects at a time; they remained thermally neutral by adjusting their clothing. Subjects assessed perceived air quality and SBS symptoms, and performed simulated office work so that their productivity could be assessed. The results of the study confirm the benefits of proper ventilation of indoor environments.
