Mitigating the Urban Thermal Environment of Tokyo through a Cluster Planning

Abstract

Tokyo suffers a lower land use efficiency and environmental problem. In this study, we have a proposal of urban plan for Tokyo in order to solve the problem of worse living condition. This proposal plan is called “Cluster Model”, which introduce the high rise building into the projected area to save the land and regain the open space. And then a theoretical model to predict the thermal environment in the urban area has been introduced. Using this model, the effect of the green area and urban structure on the urban thermal environment can be determined. The results suggest the green area has a significant effect on lowering the air temperature. Through comparison of the thermal environment between the present and cluster model, the efficiency of the cluster model to mitigate the environment in the urban area has been proved. © 2002, Architectural Institute of Japan.
