In addition to the former report, Natural ventilation rate using solar chimneys in a sustainable college building NO.14 was measured using tracer gas method in Spring, Autumn and Winter. And air change rate was about 0.3〜0.5times/hour. At the same time, temperature distribution in the building, air movements and weather condition are also measured. Those data are used to multi-rooms ventilation calculation. As a result of repeating improvements of the calculation model, the calculation result came to accord with measured value well.
