EMERGENT Architecture 設計 貴陽花溪城市中心大廈 Huaxi Urban Centre Tower
由 EMERGENT Architecture 建築師事務所設 計之「花溪城市中心大廈(Huaxi Urban Centre Tower)」是一棟高達110米的辦公大樓,屬於中國貴陽市花溪城市中心區建設案的一部分。該大廈的建設又重遇了大樓基礎建設系統的問題。設計的目的不 是簡單的將技術形象化,而是要創造一種科技氛圍,這種氛圍是通過半透明、朦朧的異域燈光和顏色效果來實現的。然而,這也是將機械裝置與其他建築設施以傳統 的交叉層疊的方式進行結合,從而實現了這種相互融合的形式。
設計的出發點是是將管道系統從建築中心移到室外。玻璃外牆上安裝了多層管道,使其呈褶皺狀以流通空氣。這些褶皺沿著大樓幕牆一週,在每層的一些特定位置處與地壓裝置相連接。
在玻璃管道牆的表面還有一層較為疏鬆的覆層,作為那些管道的固定裝置和大樓外牆裝飾。該覆層是用穿孔金屬板製作的,白天可以作為遮光板,在室內還可以透過去欣賞外面的景色。
夜晚,覆層後面的玻璃管道牆閃閃發光,呈現一種優雅與神秘的色彩效果,同時還可以反光並將大廈的輪廓刻畫得更加光彩熠熠,其外形與色彩也與當地壯美的景色融合在一起。

Structures of contemporary high-rise buildings, though often limited by material capacities, dynamic lateral forces, and legal constraints, have recently undergone a renaissance of investigation. The list of known structural types such as moment frames, braced frames, trussed tubes, and shear wall systems has been expanded to include new morphologies and materials including non-metric cellular formations, exoskeletal lattices, and next-generation carbon fiber composite networks.
Experimentation in the realm of mechanical systems, however, is far behind. Most high-rise buildings are still outfitted with a hidden and expensive network of metal ducts which are run through structural cores or between structural beams in an ineffectual and often conflictual way. Mechanical systems have become the ‘other’ of structure, relegated to dark inaccessible spaces, inevitably remaining architecturally inert. At one moment in recent history, however, architects began turning buildings inside-out for the sake of the expression of HVAC systems. That movement in architecture-- Structural Expressionism-- was nevertheless problematic from the start since projects effectively transported known HVAC systems wholesale to the exterior without any productive transformation in terms of form, organization, or atmosphere.
This project revisits the problem of architecturalizing tower infrastructural systems. Rather than expressing the literal image of technology, the goal is to create technological ambience. This ambience is defined by translucency, shrouding, and exotic lighting and color effects. But it is also the result of hybridizing mechanical systems with other building systems in a way that cross-wires traditional hierarchies and produces synergetic forms.
The point of departure for the design was to allow ductwork to migrate out of the central core toward the exterior. The glass envelope begins to take on duct behavior by delaminating to create pleats where air can flow. These pleats branch and run across the building facades, linking to floor plenums on each level at several locations along the perimeter.
A second layer of loose-fitting skin wraps the glass duct-skin, registering the pleats and shrouding the building. This shroud is made of perforated sheet metal. It acts as a sunscreen during the daytime, while nonetheless allowing views through.
At night, the glass ducts glow from behind the shroud, creating elegant color and depth effects, reflections, and silhouettes. Their freeform morphology and variegation begin to create associations with the lush natural terrain of the site.
