In order to control the indoor air pollution resulting from microbes, it is important to clarify quantitatively the actual contamination status of the microbes in air -conditioning systems which greatly affects the indoor air quality.This paper reports the results obtained from the survey about the growth environment and the pollution actual status of microbes in the air-conditioning systems equipped in eight office buildings.The main conclusions obtained from this research are as follows. (1) By measurement of the growth speed of Eurotium herbariorum which used as a biosensor in this study, it was shown clearly that the environment down stream of a coil is favorable to the growth of microbes. (2) On some object surfaces of an air filter, a coil, and a humidifier, 1 000 or more microbes per square centimeter were measured.
