The "Breathing Wall" proposed by the authors was designed by including interior/exterior materials. The experimental bodies were installed on opposite sides of an outdoor scale mock-up house model. In the results of the experiment, it was found that, 1) the amount of ventilation under weak wind conditions in the mid-term decreases about 30 percent compared with the simulation value of the steady state. Therefore, under those conditions, it is necessary to count in a safety factor of about 30 percent, 2) higher thermal insulation properties are expected under natural wind pressure conditions than under constant wind pressure conditions, 3) no internal condensation was found to continuously occur in natural weather conditions, 4) no adverse effects on indoor living space were found even though low temperature distribution was found in the corner between the wall and floor by cold outdoor air flowing through the wall in the winter.
