Research on the relationship between human behaviour and climatic characteristics in a public open space. Survey and analysis in Saitama New Urban Center area

Abstract

In urban area, making the attractive public spaces is effective one way of creating a public life or increasing the value of area. In Japan, there have been many public spaces which are not well used because the flexible utilization of public spaces including road, park and river has been limited due to some regulations. However, in accordance with the revision of “Act on Special Measures concerning Urban Reconstruction” and so on, stakeholders have been able to review the making public spaces which are stimulated flexibility use because the utilization of public spaces have been permitted by private business operators or locally area management association. In case of practical and tactical public space making, it is necessary to gain a public consensus through stakeholders discuss what kind of good effect will be made by the alteration of public spaces by communication. Therefore, it is effective to visualize based on the data verification and accumulate the results for short-term and temporary alteration of public spaces such as social experiment. At the same time, integrating the consideration of thermal environment and wind condition will contribute to make more attractive public spaces. Therefore, this study aims obtaining the basic data necessary for making the attractive public spaces considering thermal environment and wind condition in Saitama New Urban Center Area which is central business zones. Specifically, this study progressed via the following steps: 1) activity investigation; 2) thermal environmental and wind condition survey and numerical simulation results; 3) analyzing the relationship between 1) and 2). In addition, it attempts to make analysis focusing strong wind for high-rise building because the high-rise buildings are lined in many parts of Saitama New Urban Center Area. Also, these results are intended to make use of designing attractive public spaces in Saitama New Urban Center Area.
