This paper presents a numerical simulation method to predict and evaluate the thermal environment in the developed urban locations where void-brick walls with evaporative cooling effect were applied, using the 3D CAD-based simulator developed by the authors. The thermal modeling of a void-brick wall was proposed from the experimental data and calculation algorism of its surface temperature was integrated into the simulator. A case study was carried out to quantify the thermal improvement of the void-brick wall applied to a bus waiting arbor. The simulation results show that the developed simulation tool can be used as a design tool to evaluate the thermal effect of the void-brick wall on the urban built environment.

This study developed an environmental design tool by combining an outdoor thermal environment simulation with 3D-CAD system performed on personal computer. The outdoor thermal environment simulation applied in this development is able to predict surface temperature distribution of urban blocks taking the spatial form and materials into consideration. Pre- and Post-processing methods were developed considering actual design process. This development actualizes the input and output process using GUI function. The CAD models created by ordinary drawing process are automatically transformed into the mesh model for the calculation. Also the design parameters, inputted in the CAD model drawing process are converted to the parameters used in heat balance calculation. The output of surface temperature distribution is visually displayed onto CAD model.

We proposed a "Breathing Wall," a climate-conscious architectural member with multi-airlayered body constructed of aluminum foil sheets having many fine circular perforating holes installed in the wood panel, in order to be used in a passive ventilation system designed for a temperate and humid climate region. One-dimensional numerical simulation model of the horizontally situated "Breathing Wall" was constructed considering simultaneous transfer of heat, air, and moisture, based on available/obtained data. The numerical simulation, obtaining the result fitting our experimental data, was found to reproduce characteristic phenomena in a steady state inside the "Breathing Wall."

In order to make clear the effect of rooftop lawn-planting on the thermal environment, outdoore xperiments were carried out with lawn-planting mock-ups throughout two years. This paper for the first part of our study describes the outline of mock-ups and measurement items and measuring methods. Main subjects of the paper are about diurnal and annual characteristics of heat budget for the foliage layer of lawn-planting. The following items were analyzed with the experimental data. 1. Reflected solar radiation from the surface of lawn. 2. Radiant temperature of lawn and temperatures in the lawn-planting layers. 3. Heat flow below the layer of foliage. 4. Heat capacity of the layer of foliage.

This study quantifies the convective heat transfer coefficient (CHTC) of the entire crown of Zelkova serrata under outdoor conditions. The CHTC is determined from whole-tree heat balances for two individual trees which differ in their transpiration rate. The whole-tree transpiration rate of the irrigated tree was measured by a highly accurate, large weighing lysimeter, while the leaf temperatures were measured by infrared thermography. The estimated CHTC was hc=7.9U+17.2 (R2=0.56, U: representative wind speed for the site) for the entire crown and hc= 8.3u+18.2 (R2=0.77, u: wind speed near the leaf) for the individual leaf. The CHTCs were identified as being double the value given by the Jürges formula, due to the size and amount of flutter of the leaves.

This study develops an environmental information visualization system for supporting thermal environment design in city planning. This system is constructed on a all-purpose GIS software. As visualization methods of 3D models, wire frame, surface model and solid model are applied according to a target scale or the characteristics of environmental information. The developed system is able to display urban planning data, landscape, thermal environment and historical data in multi-scale and multi-temporal using the 3D GIS.

都市における熱環境解析の第一段階として, 前報で物理的裏付けをはかった航空機リモートセンシングデータを用い, 夏季・晴日における住宅地の熱環境の実態を示した。さらに, 各種タイプの住宅地を中心にして, それらの熱環境を比較検討するとともに, 熱環境と土地被覆率との相関・回帰分析を行い, 両者の関連性を考察した。すなわち, 住宅地の熱環境要素である可視域と近赤外域の分光反射率, 昼と夜の表面温度などは, 住宅地のタイプと使用されている材料によって異なる, 材料も考慮した土地被覆の実態を知ることによって, それぞれの熱環境要素が回帰できる, ことなどを明らかにした。今後の問題としては, 熱環境の日変化, 季節変化の解析, さらに住宅地から一般の都市環境への拡張などがあげられよう。また本報ではMSSデータの解析の中で, 建物立面の補正など手作業によったが, 計算機による補正方法も検討する必要があると考える。おわりにあたり, 本研究は「財団法人 日本造船振興財団日本海洋総合学術診断プロジェクト」に参加して得られた成果の一環であることを記すとともに, 東京大学教授豊田弘道先生, ならびに愛甲敬氏をはじめとする財団の方々に感謝の意を表します。
