Analysis of the Effects of Floor Area Ratio Change in Urban Street Canyons on Microclimate and Particulate Matter

Air pollution, such as particulate matter (PM), and extreme weather are causing increasingly complex problems socioeconomic damage in urban environments year-round. This study predicts air pollution changes that occur street canyons the basic data necessary for research on energy conservation. Changes PM microclimate elements based change floor area ratio analyzed. In addition, effects of distribution factors examined. Based ratio, high-concentration was negatively correlated with PM2.5, PM10, O3, NO2, NOx, Ta, Tmrt, Tsurface. Extreme heat observed to be Tmrt Tsurface, cold NOx. The higher wind speed (WS), indicating a positive correlation between two factors. Tsurface were WS showed negative correlations results this can used derivation evaluation indices determine prediction response strategies respect combination ensure suitable sustainable quality life. helps predict loads according canyon structures examines whether trees green walls effective reducing saving energy.
