| Abstract |
This study analyzes the seasonal effects of street shape and building arrangement on the sidewalk shading environments at the Gangnam district in Seoul, Korea. Specifically, this study compares the shading environments of pedestrian streets in summer and in winter by analyzing the amount of solar radiation on the sidewalks. The results show that the amount of solar radiation on the pedestrian street running north-south is larger than that running east-west during the summer. This means that it is necessary to handle the streets running north-south of higher solar radiation with proper strategies to improve walking comfort in summer. On the other hand, this study finds that the streets running east-west rather than north-south show larger seasonal differences in the amount of solar radiation. This result means that the shading environment on a pedestrian street is affected not only by the direction of the street, but also by the height and volume of buildings along the street and the size of surrounding roads. Therefore, in order to improve the walking comfort in accordance with the shading environments of the pedestrian street in summer and in winter, the direction of pedestrian street should be considered first and it is necessary to actively incorporate the height and volume of the surrounding buildings and the characteristics of the adjacent roads into street design practices. |
