Field Measurement and Urban Design Analysis on Summer Wind-comfortable Environment in Urban High-density Districts

Abstract

The interaction between urban building layout and urban external wind resources has determined the characteristics of the internal wind environment in urban built environment so as to have certain influence on the urban heat island effect, building energy consumption, the thermal comfort inside and outside the building, the air quality and the health of the residents have a certain influence. This study attempts to understand the correlations between urban design elements and wind environment. The method is to use field tests of physical environmental indicators to obtain the microenvironmental wind speed under the pedestrian scale in three selected pedestrian streets in Beijing: Wangfujing, Beijing, Qianmen Street Dashilan and the wind direction and wind speed data outside the city have also been has collected. The urban design elements including street width, landscape design, pavement materials, and others are analyzed in terms of the impacts on wind environment.
