In this study of sensory indicators to evaluate odor, we focused on Fanger's indicators which are based on unpleasantness of body odor and the others based on odor threshold value. We investigated the relationship between both indicators and points of attention to use the indicators in the management of indoor air quality. We distinguished indicators reflecting the quantity of odorous contaminants from the pollution source load on odor evaluation indicators. The correspondences between indicators based on unpleasantness of body odor and odor threshold value were examined. We found that the relationship between decipol and odor concentration reflecting the quantity of odorous contaminants is proportionate. The following three factors were considered in the employment of the odor evaluation indicator: the determination of acceptable levels, design of ventilation and deodorization based on estimation of the pollution source load, and check of the fulfilling the acceptable level and evaluation of ventilation and deodorization efficiency. We investigated the effectiveness of odor evaluation indicators from three kinds of viewpoint and strong and weak points of each indicator were obtained.
