Abstract

In office environment exposure to volatile organic compounds (VOCs) and formaldehyde (HCHO) may cause symptoms. One room with and without reported occupants’ symptoms were selected in a large office building. The aim was to follow the circadian rhythm of the total volatile organic compounds (TVOC), HCHO and carbon dioxide (CO2) concentrations and the temperature (T) and relative humidity (RH). Both rooms (no occupants) were monitored online (24/7) for one week in summer 2014. The room with reported occupants’ symptoms had high T, and showed pulses of TVOC, HCHO and CO2 during night, however the measured concentrations did not explain indoor problems. Formaldehyde and TVOC pulses were linked to the T increase and lack of ventilation. The TVOC, HCHO and CO2 values were <230 μg/m3, < 40 μg/m3 and <450 ppm, respectively. Building monitoring provides valuable data on the emission and conditions of buildings and help to detect ventilation dysfunctions.
