We proposed a "Breathing Wall," a climate-conscious architectural member with multi-airlayered body constructed of aluminum foil sheets having many fine circular perforating holes installed in the wood panel, in order to be used in a passive ventilation system designed for a temperate and humid climate region. One-dimensional numerical simulation model of the horizontally situated "Breathing Wall" was constructed considering simultaneous transfer of heat, air, and moisture, based on available/obtained data. The numerical simulation, obtaining the result fitting our experimental data, was found to reproduce characteristic phenomena in a steady state inside the "Breathing Wall."
