基于节能的办公建筑采光中庭形态优化设计

采光中庭由于其独特的空间设计给人们带来不一样的视觉感受，已在办公建筑中广泛应用，中庭结构的合理设计对建筑自然采光、建筑能耗具有很大的影响。通过Autodesk Ecotect和Ra-diance数值软件，模拟计算不同中庭平面布局、尺寸比例以及幕墙朝向对办公建筑自然采光系数、全年自然采光满足率DA、天然采光照明节能率、室内照度全年满足率的影响；在模拟分析的基础上，采用Designbuilder数值软件比较分析采光中庭形态优化设计对办公建筑人工照明、采暖空调能耗的影响。

Optimal Design of the Lighting Atrium Form for an Office Building

The lighting atrium has been widely used in office building, and rational design of atrium structure has a great influence on natural lighting and energy consumption, because the unique space de-sign brings different visual perception to people. The daylight factor, DA, energy-saving rate of daylighting lighting and RAD illuminance, which influenced by various plane layout and dimension scale of atrium, and glass curtain wall direction, are expounded through numerical software Autodesk Ecotect and Radi-ance. The numerical software Designbuilder is utilized to compare and analyze the influence of the optimal design of various lighting atrium forms to the artificial lighting, heating and air-conditioning energy con-sumption.
