本研究的主要目的是揭示住宅区建筑密度与行人层平均风速之间的关系。本文首先介绍了从日本实际城市中选取的22个居民区的风洞试验结果。结果表明，建筑物总覆盖率与平均风速比之间有很强的相关性。其次，利用风洞试验结果和日本几个主要城市的气候条件，对案例研究区域进行风环境评价。提出了利用建筑物总覆盖率制定住宅小区可接受风环境指标的方法。(c)2007爱思唯尔有限公司保留所有权利。
The main purpose of this study is to reveal the relationship between the building density and the average wind velocity at pedestrian level in residential neighborhoods. This paper firstly presents the results of wind tunnel tests on 22 residential neighborhoods selected from actual Japanese cities. The results show that there is a strong relationship between the gross building coverage ratio and the mean wind velocity ratio. Secondly, the wind environment evaluation for case study areas is performed by using the wind tunnel results and the climatic conditions of several major Japanese cities. The development method of guidelines for realizing acceptable wind environment in residential neighborhoods using the gross building coverage ratio is proposed. (c) 2007 Elsevier Ltd.
