1) The study is the design simulation of the semi-detached housing model with environment adjustment mechanism. located in detached housing area in rather high density urbanized context. The model had been established by reorganizing the environmental condition in micro-climate. For the study, we made 4 different basic conceptual models of semi-detouched housing, and conceived the environmental features through the detailed outdoor experiment of 1/10 scale modls.2) As the result, we made following conclusions, as the basic micro-climate condition :-There is considerable wind flow difference between the central axis zone and the wall surface flow zone around the building.-The convection type environment condition is rather effective, when the slit between detached houses is closed.-The interior ventilation caused by the pressure gap between windward and leeward is evidently superior.-4 basic types of standard. irregular, courtyard, and irregular-slit has clear environmental difference.3) Successively, we made further CG simulation study on the courtyard type and the wedge type, which is presumably more useful in reality. We proceeded the simulation on 3 models with 3 wind directions and 5m/s wind speed at 10.0m height. As the out put, we got horizontal wind vector map (h=1.0,3.0m), horizontal wind speed map (colored), wind streamline map (h=3.5m). Through the investigation, we proved the effectiveness of the courtyard type and the wedge type.4) Finally, we proposed a urban type semi-detached housing model transformed from the courtyard type.

1)本研究为具环境调节机制之半独立式住宅模型之设计模拟。位于高密度城市化背景下的独立住宅区。通过对小气候环境条件的重组，建立了该模型。本研究制作了4种不同的半开放式住宅基本概念模型，并通过1/10缩尺模型的详细室外实验，构思了半开放式住宅的环境特征。2）研究结果表明，作为基本微气候条件，建筑物周围的中轴线区域与墙面气流区域存在较大的风流差异。对流型环境条件是相当有效的，当独立房屋之间的缝隙是封闭的。由迎风面与背风面压力差引起的室内通风具有明显的上级性。四是基本标准。不规则、庭院、不规则狭缝有明显的环境差异。3）接着，我们对庭院型和楔形进行了进一步的CG模拟研究，这可能更有现实意义。在10.0m高度上，我们在3个风向和5 m/s风速下对3个模型进行了模拟。输出结果得到了水平风矢量图（h= 1.0，3.0m）、水平风速图（彩色）、风速流线图（h=3.5m）。通过调研，验证了院落式和楔形住宅的有效性。4）最后，提出了由院落式改造而来的城市型半独立住宅模式。
