The purpose of this study is to examine the relationship between thermal environment and natural ventilation within Machiya in Naramachi, which is the old city of Nara, by conducting field measurement about thermal environment in summer. In this study, we measured the following variables in and around the house: air temperature, humidity, wind velocity, globe temperature, horizontal solar radiation, the difference of pressure between the front and the back courtyards, etc. Thorough the investigation, the following three knowledges were clarified: (1) The surface temperature on the soil was cooler than that pebbled with small stones in the back courtyard, (2) The indoor air temperature was cooler than the outdoors, (3) The wind velocity at the zashiki room (a tatami room) was strongly affected by the velocity at the front courtyard than that at the back courtyard. The future direction of this study is to examine the relationship between the flow and the thermal environmental fields by using CFD analysis.
