Abstract

<p>The purpose of this study is to analyze how surrounding conditions of pavements affect thermal comfort by water retentive pavements during the summertime. Firstly, substantial urban areas were developed as 3D-CAD models by using thermal environment simulation tool. Then, the surface temperature distributions of the actual condition with ordinary asphalt pavements and of the condition in which asphalt pavements were replaced by water retentive pavements were calculated. Finally, relationships between the differences of surface temperature and the surrounding conditions of location were analyzed. The result indicated that the effect of water retentive pavements was small on the north side of buildings and trees compared with others. Not only that, the result revealed that the north part of east-west road had a large effect on thermal comfort while the effect of north-south road varied in place to place.</p>
