Indoor air quality (IAQ) was investigated in 19 open-plan offices and 30 office rooms in order to compare the differences in these two different types of office environments. No moisture or mold problems had been reported from the present buildings, but the employees had complained about the IAQ. The results revealed only slight differences in the IAQ of the two different types of office enviro...
