New index which expresses the unevenness in space for natural ventilation and cross ventilation is examined from movement and diffusion of tracer gas, in consideration of time scale of airflow field. And 2-zone model is examined as the macro model in consideration of unevenness. 1. Volume index is derived from concentration at exhaust to gas input at supply. And it is confirmed the index expresses the unevenness in space. 2. It is confirmed to able to grasp the overview of velocity distribution from the volume index. 3. 2-zone model based on the volume index is presented. And correspondence to the transient analysis is considered. 4. The identification method of the interzonal airflow rate is examined.日本建築学会Journal Articleapplication/pdfhttp://hdl.handle.net/2115/50477https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/50477/1/AIJ.576.29-36.pdf1348-0685AA11830377日本建築学会環境系論文集57629362004-02-28jpn日本建築学会、本文データは学協会の許諾に基づきCiNiiから複製したものであるpublisher
