自然通风与采光耦合效应对外窗参数设计的影响研究OA

The synergistic optimization of natural ventilation and daylighting is crucial for reducing building energy consumption and improving indoor environmental quality.To ad-dress the shortcoming of existing studies that lack an analysis of the coupled effect between the two under dynamic climate variations,this study proposes a dynamic evaluation frame-work integrating seasonal climates and occupant comfort requirements.Taking office build-ing in the subtropical humid climate zone as research objects,this paper constructs a multi-criteria evaluation system including air velocity,air age,ventilation rate,daylight factor and glare index.Monthly weights were dynamically adjusted based on normalized temperature-humidity and illuminance data.Through simulations,a quantitative analysis of exterior window design schemes was performed to reveal the influence rules of window-to-wall ratio,window sill height,and window opening height.The results indicate that the window-to-wall ratio has the most significant impact on the coupled effect of ventilation and daylighting,followed by the window sill height,while the window opening height has the least influence.The optimal parameter combination—with a window-to-wall ratio of 0.25,a window height of 1.2 m,and a window sill height of 0.9 m—can effectively balance ventilation,daylighting,and energy consumption control.Furthermore,the application of external shading devices in summer and thermal-insulation curtains in winter can mitigate the impacts of extreme climate conditions.
