建筑遮阳条件下的自然采光设计策略

The Natural Lighting Design Strategies in Conditions of Architectural Shading

建筑遮阳装置的普遍应用会使采光口的采光效率大为降低,甚至会阻断使用者与自然景观的联系。文章通过绘制图示和实例阐述了在满足建筑遮阳的条件下,能够提高自然采光效果的设计策略:一方面是通过附着于建筑界面上的水平外遮阳装置阻挡阳光入射或对光线进行调节;一方面是通过对建筑采光口自身的设计改变采光方向和减少阳光直射。以此来平衡建筑遮阳和自然采光之间的矛盾,恢复采光口的多重功能。

The universal application of building shading devices will decrease the efficiency of the daylight opening and separate the contact between people and natural landscape. The paper elaborates the design strategies which can improve natural lighting effect with architectural shading. On the one hand, obstruct incident sunshine or regulate radial through the building shading devices on the architecture surface .On the other hand, change the direction of naturel lighting and decrease direct sunlight through the design of the daylight opening.These strategies will compromise the contradiction between the architectural shading and natural lighting,and restore the multiple functions of the daylight opening.
