碩士 === 國立臺北科技大學 === 建築系建築與都市設計碩士班 === 107 === This study is mainly aimed at the discussion of ventilation efficiency, comfortability and energy saving in the single-family space of the collective residence in summer.By collecting relevant literature,Confluence affects ventilation factors,Use Design Builder dynamic energy simulation software,CFD numerical analysis, EN15251 thermal adaptation simulation To explore the environmental benefits of indoor space design. According to relevant domestic and foreign literatures.The CFD simulation results were collected, the indoor simulated ventilation evaluation analysis was carried out. The results show that the indoor ventilation potential (VPs) and the EN15251 thermal adaptation standard have positive correlation, and the correlation coefficient is R=0.828, P=0.000. This simple evaluation model provides a numerical assessment of indoor ventilation simulation results. To provide reference for architectural planning and design time, this study uses TMY3 meteorological data to simulate indoor corridors, sideways windows, window sizes, and indoor ventilation potentials for use in different areas of North, Central, and South. In terms of corridors and windows, the ventilation potential is up to 28.72% under the design of one-side ventilation and three-side ventilation. The ventilation potential is improved under the design of double-sided ventilation without corridor space. 17.43%; the window facing is the three sides of the corridor space planning > double side > one side; no corridor space planning under the two sides > three sides > one side. In terms of window opening size, the higher the ventilation window, the higher the ventilation effect. Finally, according to the indoor ventilation potential assessment results, the larger the value, the higher the indoor ventilation efficiency, the higher the relative comfort will be, and the air conditioning use will be reduced, so the indoor wind can be designed and planned. The environment is simulated and designed, and the energy efficiency of subsequent users is greatly improved.
