西雅圖機場航廈增建，木構大樹地標驚艷亮相
西雅圖機場航廈增建，木構大樹地標驚艷亮相
美國建築師事務所 Miller Hull Partnership 與 Woods Bagot 合作完成西雅圖塔科馬國際機場 (Seattle-Tacoma International Airport) 的 C 航廈增建計畫。
這次更新是西雅圖機場 2023 年啟動「Upgrade SEA」提升方案的核心工程之一。
增建範圍涵蓋C航廈和部分D航廈，新增四個樓層，讓既有航廈樓地板面積直接翻了一倍。建築是楔形平面，屋頂微微傾斜，上面鋪滿太陽能光電板。
外牆由南向和西向交替排列的玻璃板組成，採用電致變色玻璃，能隨日照自動調整透光度——陰天讓視野放到最大，晴天擋住眩光。
Miller Hull Partnership 的負責人 Rich Whealan 表示，航廈會根據太平洋西北地區多變的光線與天氣自動調節，即便在雲層厚重的陰天，內部空間依然能維持舒適光度，並讓旅客能遠眺飽覽機場跑道與奧林匹克山脈 (Olympic Range) 的景緻。
室內規劃圍繞著中央的「市集」區域，此處設有階梯式座位，中央立有一根覆蓋木質飾板的巨大柱體，並向頂部延伸擴張至天花板；這座被稱為「C航廈之樹」 (Tree at C)的結構，參考了太平洋西北地區的茂密森林，使用在地取材的天然材料；中央樓梯與這棵木構大樹做為地標，也是航廈內的導航核心，提供旅客駐足停留的空間。

此次增建工程案還有幾項指標性的里程碑，包含機場首度安裝太陽能板、首次採用全電力系統，並以獲得 LEED 白金級 (LEED Platinum) 認證為目標。
在航廈高處的角落，更規劃了一座玻璃包圍的戶外觀景露台，正對著機場跑道，讓旅客能近距離欣賞飛機起降。
透過軟硬體更新，不僅讓機場基礎設施更具效能，相關更新計畫還包括擴寬道路與更有效率的行李輸送系統，西雅圖機場的國際航廈升級計畫目前則仍在設計階段。

Woods Bagot 團隊近期亦完成了洛杉磯國際機場 (LAX) 與西雪梨國際機場 (Western Sydney International Airport) 等交通樞紐專案，這些作品同樣展示了該事務所對木質飾板的熟練運用。

西雅圖機場增建完工，航廈裡長出一棵巨大的木構造「樹」，拱在旅客聚集區的上方
西雅圖塔科馬國際機場（Seattle-Tacoma International Airport，簡稱SEA）的C航廈擴建工程完工，由建築事務所The Miller Hull Partnership和Woods Bagot合作設計，屬於2023年啟動的「Upgrade SEA」機場升級計畫的一環。
增建範圍涵蓋C航廈和部分D航廈，新增四個樓層，讓既有航廈的樓地板面積直接翻了一倍。建築是楔形平面，屋頂微微傾斜，上面鋪滿太陽能光電板。外牆由南向和西向交替排列的玻璃板組成，採用電致變色玻璃，能隨日照自動調整透光度——陰天讓視野放到最大，晴天擋住眩光。
The Miller Hull Partnership主持建築師Rich Whealan說：「在太平洋西北區多雲的日子裡，航廈會讓旅客看見跑道和遠方的奧林匹克山脈（Olympic Range）；柔和均勻的日光灌進室內，讓人和外面的風景保持連結。」
航廈內部最主要的空間叫做「市集區（marketplace）」，是一個開放的聚集區，中央有階梯式座位，四周圍繞著餐飲和購物攤位。市集區的正中央立著一根巨大的柱子，柱身包覆木板，木板從柱身延伸到天花板，形成一個拱形的木構造覆蓋層。設計團隊叫它「C航廈之樹（The Tree at C）」，用材取自太平洋西北區的在地天然材料，呼應當地的森林意象。設計團隊把中央樓梯和「樹」定位為旅客辨認方向和停下來休息的錨點。
建築上層的角落設有一座露天觀景平台，面向跑道，三面環繞玻璃牆，頭頂由太陽能板覆蓋。
這次擴建為SEA機場帶來多項第一次：第一座太陽能光電板系統、第一套全電氣化設備，也是機場第一棟朝LEED白金級認證邁進的航廈。除了航廈擴建，機場同時也加寬道路、更新行李系統，國際航廈的改建則仍在設計階段。
In collaboration with the Port of Seattle, the C Concourse Expansion (CCE) is one of several major projects planned for upgrading Seattle-Tacoma International Airport (SEA) under the Upgrade SEA initiative launched in 2023.
The expansion spans Concourse C, as well as parts of Concourse D and more than doubles the size of the existing buildings by adding four new floors.
The final building is wedge-shaped, with a slightly sloping roof covered in photovoltaic panels and a crinkled glass facade.
The alternating south- and west-facing glass panels were made with electrochromic glass to minimise glare and optimise daylight, according to the team.
"As the day progresses, the concourse responds to the changing light and weather of the Pacific Northwest," said The Miller Hull Partnership principal Rich Whealan.
"On overcast, cloud-rich days, visibility is maximised to highlight the views of the airfield and Olympic Range, while soft, even daylight fills the interior, enhancing comfort and connecting travellers to the surrounding landscape."
Inside, the building is organised around a large "marketplace" area, which contains stadium seating and a large column covered in timber panelling that expands onto the ceiling.
Dubbed the Tree at C, the structure references the forests of the Pacific Northwest, according to the team, and is made of natural materials sourced from the region.
Food and shopping kiosks surround the area, while the central staircase and Tree were designed as a "point of orientation and a place to linger".
The expansion also includes an open-air lookout terrace, which is located in one corner of the building on the upper levels and faces the airstrip,
It is enclosed in glass along its walls and covered by the photovoltaic panels overhead.
The project integrates "several firsts for SEA", including the airport's first photovoltaic panels, first all-electric systems, and will be the first to target LEED Platinum certification.
Other updates completed at the airport include widened roadways and a more efficient baggage system, while an update to the building's international terminal is still in the design phase.
Woods Bagot has completed two other recent airport projects at LAX and the Western Sydney International Airport, both of which feature timber panelling.
