In order to manage and maintain a hygienic indoor environment, it is necessary to estimate concentrations of contaminants such as airborne particles and disease agents. For these estimations of the contamination, a data assimilation method was used with data previously measured. In this study, the Variational Continuous Assimilation method was applied to estimate indoor contamination sources. For an objective room which has neither circulation of flow nor temperature distribution, VCA method was validated. However, for an objective room has circulation and temperature distribution, the validity was seemed to be limited.
