Abstract

快適な都市空間づくりが主要なテーマとなってきた現在,都市の熱環境が人の温冷感に及ぼす影響を正しく評価することも重要である.その評価のための温熱指標確立のための要素は種々であるが,屋外環境では,特に,日射の影響が地物での反射も含めて大きい.そこで,本研究では,多重放射を考慮して,日射と建物など地物の影響を組み入れた平均放射温度の導出を試み,その評価法として提案する.また,多重放射の影響については,射度と本研究で定義するIncidence Factorにより考慮し,それぞれによる平均放射温度を導出し,その特性について検討する.

It comes to be more important to evaluate the effect of thermal load in outdoor thermal environment or urban climate on man's thermal sensations. In urban environment, especially, the effect of solar radiation (short-wave radiation) involving interchange between surfaces is larger than in indoor environment. The authors try to define a mean radiant temperature including the effect of long and short-wave radiation involving interchange between surfaces. The temperature is defined by radiosity and incidence factor to evaluate the effect of interchange between surfaces. The incidence factor is defined almost same absorption factor, and by the incidence factor, it is easier to calculate the effect of radiation interchange outdoor environment. And the authors study the characteristic of the effective radiant temperature on two typical outdoor models, and considers that it is important in urban environment to include the effect of the long and short-wave radiation interchange between surfaces.
