| Outline of Final Research Achievements |
Using a drone equipped with a dual camera that can capture visible and thermal images simultaneously in combination with photogrammetric technology, a long-wave radiation module, which is a 3D model of buildings and trees with long-wave radiation intensity information, was generated. Morever, the theory of rapid-estimation of the long-wave radiation environment in urban area using these modules was established.
The accuracy of the quantitative values of the modules was validated by comparing them with the mesuremental results of surface temperature distribution of a small building and a single tree on the campus of Tohoku University in Sendai, Japan. It was confirmed that the estimation of long-wave radiation intensity was possible with an average error of less than 5%.

| Academic Significance and Societal Importance of the Research Achievements |
猛暑環境下では、高温の地面や建物等からの長波放射が人間の温熱快適性に与える影響は非常に大きく、これを制御する空間設計が求められる。しかし、長波放射の予測には一般的に高い計算コストを要し、設計最終案のアセスメント段階で初めてその熱的影響が評価されるのが現状である。本研究が提案した都市空間内の長波長放射環境の高速推定（Rapid-estimation）理論を熱環境設計プロセスに組み込むことで、設計の初期段階から長波長放射の影響の検討が可能となる点で、本研究の意義は大きい。
