Increasing impermeability area by expanding built-up area and luck of drainage capacity of basin of side ditch, sewage line and rivers bring down water inundation. Therefore improving rainwater drainage system is an urgent need. Our previous studies proposed pipe and drain, pump station and rainfall harvesting facility construction as methods of improving rainwater drainage system. And we simulated and calculated cost benefit when these were constructed. In the result, we showed that rainfall harvesting underground is the most effective way as a rainwater drainage system. On the other hand it is difficult to build a new facility in a city having overcrowded population. In this paper the new way of rainfall harvesting is proposed. Installing those equipments on the top of the building also mitigates the inundation damages. In addition, rainfall harvesting on the top of the building have heat environment mitigation by heat of evaporation when rain water evaporate. This paper shows that rainfall harvesting on the top of the building is effective to runoff suppressant and heat environment mitigation by an observation on the top of the building and runoff analysis., 【査読有】}, pages = {43--50}, title = {屋上貯留のもつ雨水流出抑制効果及び熱環境緩和効果に関する研究}, volume = {16}, year = {2011}, yomi = {イソガイ, ジロウ and オカベ, マサト and コノシマ, タケヒコ and ヤマダ, タダシ} }
