Many kinds of passive cooling devices can be found in Japanese traditional vernacular houses. They are available for us to get good ideas on the research and development of new passive cooling systems applied to the modern houses. This paper shows the results of field survey and simulation on thermal environments of the traditional vernacular houses in Northern Kyushu in order to make clear the relations between building elements and thermal environments. The results are concluded as follows. 1) It is effective to make use of convective, radiative and evaporative heat exchange at the indoor ground surface. 2) By combining gable vents of the attic with relief vents under the floor, the stack ventilation systems enhance discharge of hot air from the attic and inflow of cool air from outdoor. 3) When the envelopes and partitions with large heat capacity are cooled by night ventilation, they can be used as valuable cooling sources in the daytime. 4) It is important to keep roof insulation, exterior wall openings and solar shading devices. The spaces over the ceiling and under the floor function as thermal controling or heat absorbing ones of the dwelling rooms against outside weather conditions.
