都市の風通しに関する建物形状の影響のパラメトリックスタディ

CASBEE-HIの風通しに関する採点基準の評価を中心として

抄録

Great attention has been shown to the question about the building design and arrangement considering urban ventilation. Recent years have witnessed the appearance of several studies and rating systems from this perspective. It might be included a wind environment rating system of CASBEE-HI as a representative example. Curiously, despite the rise of studies about this rating system as an academic discipline, few have attempted to address its effectiveness.
This paper presents verification of effectiveness of a wind environment rating system of CASBEE-HI. The verification process consists of calculating the score of CASBEE-HI of random cases and numerical simulation using CFD. The results of CFD are then compared to the score of CASBEE-HI by correlation analysis. It is described from results that how a wind environment of built area is being described by a wind environment rating system of CASBEE-HI. Proceeding from what has been said in this paper, it should be concluded that a wind environment rating system of CASBEE-HI is a debatable issue.
