【摘要】：针对建筑外立面开口形式设计的分析需要,探讨了适合方案阶段建筑围护结构优化的采光、传热及自然通风综合分析方法.通过采用设计案例分析的方法,对现有采光及自然通风模型的模拟性能(精度、速度、建模难度)进行了比较.结果表明,采光系数模型以及空气流动网络模型比较适合于方案阶段的采光及自然通风综合分析;在反映开口设计形式变化的影响规律方面,相比目前应用广泛的Radiance采光模型以及CFD(computational fluid dynamics)软件通风模型,Energyplus模型计算的采光量、通风量及能耗误差均在10%以内.此外,在利用空气流动网络模型进行自然通风计算时,需要采用非均匀风压系数边界条件以准确反映开口位置变化的影响.
[Abstract]:In order to meet the need of the design of external facade opening, a comprehensive analysis method of lighting, heat transfer and natural ventilation is discussed, which is suitable for the optimization of building envelope structure in the project stage. By using the method of design case analysis, the simulation performance (precision, speed, modeling difficulty) of the existing lighting and natural ventilation models are compared. The results show that the lighting coefficient model and the air flow network model are more suitable for the comprehensive analysis of lighting and natural ventilation in the scheme stage, and reflect the influence law of the design form of the opening. Compared with the widely used Radiance lighting model and the CFD (computational fluid dynamics) software ventilation model and energy plus model, the errors of ventilation and energy consumption are within 10%. In addition, when using the air flow network model to calculate the natural ventilation, it is necessary to adopt the boundary condition of the non-uniform wind pressure coefficient to accurately reflect the effect of the change of the opening position.
