Opening and Closing Lattice Facade: Sun-Tracking Shading

A pair of circular high-rise towers, enveloped by a dynamic shading layer detached 2 meters from the main body, composed of thousands of independent triangular textile units. Each unit is an umbrella-like component that can fold and unfold, driven by a central connecting rod, opening and closing section by section according to the sun's azimuth. The image shows the facade at a single moment: the east-facing side is fully closed, the south-facing side is fully open, and the rest are in an intermediate state, thus presenting a flowing variation in density across the skin. The units are off-white PTFE textile. Avoid: shading layer depicted as static, all units in the same open/closed state, skin adhering to the main body without a gap, metal panels instead of textile.

一對圓形平面的高層塔樓,外側包覆一層與主體脫開 2 公尺的動態遮陽層,由上千個獨立的三角形織品單元組成。每個單元是一朵可以摺疊開合的傘狀構件,由中央的連桿驅動,依照太陽方位逐區開合。畫面呈現同一時刻的立面上,朝東的一側完全收合、朝南的一側完全展開、其餘處於中間狀態,因此外皮呈現一片流動的疏密變化。單元是米白色的聚四氟乙烯織品。避免:遮陽層畫成固定不動、單元全部同一開合狀態、外皮貼合主體沒有間距、使用金屬板取代織品。
