Abstract

The purpose of this study is to examine the effect of both upper wind velocity and location of Machiya in Naramachi, which is the old town of Nara, on the environment in and around Machiya using CFD analysis. The study area in the present analysis is a part of city block model of Naramachi in Edo era. The shapes and room assignment of Machiya model is simplified by references to typical Machiya where we carried out the field observation. Computational cases were set by the following two parameters: the upper wind velocity, and the facing direction of Machiya. The velocity is assumed to be 3.1m/s in the strong wind case, while 1.5m/s in the calm wind case. The facing direction is set to the following two cases: facing to southern direction (the shaded street),and facing to west direction (the sunny street). Thorough the examinations, the following two knowledges were clarified: (1) Wind direction in the main house was opposite to that of upper wind only when both the upper wind velocity was strong and the street was shaded. (2) The indoor wind velocity in the calm upper wind case was higher than that in the strong case.
