The ground surface temperature in the crawl space in a dwelling building is lower in summer than the outdoor air temperature or the room air temperature by solar shading and water evaporation. The earth ground under the crawl space is available for the heat resources of passive cooling to combine with ventilation because of the large heat storage capacity of soil. The ventilation system, the sucked outdoor air into the crawl space is cooled by contact with the ground surface and this cooled air is induced in the room and exhausted to the outdoor through the attic space, is proposed and examined in this paper. Two test houses, one has the proposed ventilation system and other has ordinary attic and crawl ventilator, are built and their thermal performances are compared in the experiments and predicted in the simulations to analyze the effect of the proposed ventilation system for passive cooling. The room air themperature in the proposed system is lower about 4℃ than that in the ordinary ventilation or the outdoor air. The passive cooling force of the proposed system is estimated as 30kcal/m^2h for the crawl area in mid summer.
