一面窗子,两个世界。窗既是建筑与自然之间的气候屏障,也是建筑与自然之间的气候通道。窗的这种双重角色集中折射出建筑与自然之间“防”与“用”的辩证关系。该文通过对窗的起源及进化形态的追溯,辨析了建筑从“掩体”向“过滤器”的演进脉络,以此我们能够对建筑的本质以及建筑的生态进化方向建立更为深刻清醒的认识。 One window, two worlds. The window is both a climate barrier between architecture and nature and a climate path between architecture and nature. The double role of the window focuses on the dialectical relationship between architecture and nature and defense. By tracing the origins and evolutionary forms of windows, this paper analyzes the evolution of architecture from “bunker” to “filter”, so that we can build more on the essence of architecture and on the eco-evolution direction of architecture A deep and clear understanding.
