Outline of Final Research Achievements |
In this study, we examined mechanisms of microclimate around a pedestrian using a parasol in the summer season. During the study period, we performed the following three investigations: (1) evaluations of effects of different textiles for a parasol on both the solar and the longwave radiant environment and the thermal environment in the summer season, (2) evaluations of distributions of the convective heat transfer coefficients on the human body using a parasol, (3) examinations of microclimate around the human body using a parasol in the summer seasons. Future directions of this study are to collect basal data for making the microclimate in the summer seasons, and to evaluate effects of installing the other adaptive behavior on thermal environment in a pedestrian in the summer seasons.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果の学術的・社会的意義は、①日傘の暑熱適応効果の評価における配慮すべき点を実測、数値解析の双方において明らかとしたこと、②日傘使用の暑熱適応効果をCFDの可視化技術により明確に示したこと、が挙げられる。①については、例えば、日傘自体の日射の遮蔽性能を分析する場合、日傘下の歩行者の温熱快適性に与える影響を評価する場合、などに応じて適切な高さに日射計を配置する必要があることが明らかとなった。また②については、夏季暑熱環境への適応技術として最も手軽で実効的な技術である日傘の効果をCFD解析結果と通じて視覚的に示すことで、男女を問わず日傘を普及させる契機となる成果が得られたと考えられる。
