数値解析により,実在街区における建物からの空調排熱と対流顕熱の放出割合を明らかにした.解析システムは,屋外熱収支計算部,建物熱負荷計算部,空調用エネルギー計算部,人工排熱計算部により構成されている.12 階建の事務所ビルを対象に解析を行った結果,ガス焚吸収式冷温水発生機+冷却塔を使用する場合,空調排熱は潜熱分が大部分であるため,12 時の時点の大気顕熱負荷量には,対流顕熱が約8 割を占めた.熱源機器を空気熱源ヒートポンプチラーに変更した場合,トータルの大気顕熱負荷量が2 倍以上に増加し,空調排熱の顕熱分は対流顕熱の2 倍近くまで増加した.

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.

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.
