In this paper, two new indices, CRP1 and CRP2 (Contribution Ratio of Pollution Source 1 and 2), are proposed for evaluating the contribution of an indoor pollution source to human's breathing air quality. CRP1 refers to a ratio indicating how much of the contamination from a pollution source will be inhaled, and CRP2 refers to a ratio indicating how much of the total inhaled contaminant will be from a pollution source. Moreover, CFD methods for the two indices are developed to investigate the breathing air quality of a standing occupant or a lying occupant located in a stagnant room, which is assumed to be air-conditioned by means of displacement ventilation. The results indicate that in such a room, less of the contaminant from the above space will be inhaled by either standing or lying occupant, and it is important to make the floor clean for preventing breathing air from being polluted as expected.
