LoginUnder the conditions that the air in each room is in the state of perfect mixing and ventilation is in steady state, a method to estimate steady state concentration distribution to match an arbitrary contaminant generation distribution is proposed, using concentration data obtained from short-time tracer gas experiment. Also, a method is proposed, which is used to estimate ventilation rate by adding other available equations. The proposed method was tested on full-scale house models installed in the environmental test room, and it was confirmed that the steady state concentration by the proposed method corresponds well to the steady state concentration obtained by tracer gas continuous generating method. The proposed method was applied on one each of a single house and a collective house with high air tightness performance, for which elaborate equipment for ventilation has been adopted, and ventilation characteristics was evaluated from multilateral viewpoints.
