摘要
通过Airpak软件模拟建筑开口对自然通风效果的影响,通过计算流体力学(CFD)方法和能耗模拟软件Design Builder模拟建筑开口对建筑能耗的影响情况。以长沙典型年气象数据为基础,分析了不同朝向和开口位置对建筑自然通风效果和能耗的影响。最后,综合自然通风效果与建筑能耗大小,提出了新的建筑设计综合评价指标,利用这个指标对不同方案下的建筑进行了计算,得出建筑朝向与开口位置最优组合方式。
This paper analyzes the influence of building openings on the natural ventilation performance and the building energy consumption. The software Airpak and the building energy consumption simulation software DesignBuilder are used in the simulation. The influences of the building's orientation and the opening's position on the natural ventilation performance and the building's energy consumption are analyzed according to the Changsha typical meteorological data. A new evaluation index is proposed to compare the design schemes with consideration of the performance of the natural ventilation and the building's energy consumption. The optimal scheme combination of the building's orientation and the opening's position is obtained by the index.
