刷新世界紀錄！雪梨 Atlassian 總部大樓封頂成為全球最高混合木構造摩天大樓
刷新世界紀錄！雪梨 Atlassian 總部大樓封頂成為全球最高混合木構造摩天大樓
位於澳洲雪梨的 Atlassian Central 摩天大樓，由知名事務所 SHoP Architects 與 BVN Architecture 聯合操刀設計，近期完成封頂，宣告成為全球最高的混合木構造高樓。
這座高達180公尺的39層大樓，是知名科技公司 Atlassian 的雪梨總部，結構採用創新的混合系統，以混凝土核心筒支撐大量木材打造的地板與內部結構，最外層則由鋼骨「外骨骼」包裹；外骨骼則每隔四層樓便支撐著一座大型樓板，將整座建築垂直劃分為七個獨立的使用單元，裡面包含辦公空間、多層樓高的挑高中庭以及高空公園。
這種混合構造大大減輕了建築整體重量與碳排放，同時透過鋼骨與混凝土確保高層結構的強度與穩定度。
.
與傳統鋼筋混凝土辦公大樓相比，本建案預計能減少百分之五十的隱含碳排放，並在營運能源效率上提升百分之五十。
.
混合大量木材的乾燥施工與預製化優勢，更大幅加快了垂直興建的速度。
.
基地緊鄰雪梨中央車站，並興建於一座名為 The Parcels Shed 的歷史建築之上，舊建築過去曾是包裹收發站，後來被改建為青年旅館。設計團隊規劃將青年旅館的功能巧妙融入塔樓低樓層空間中。隨著外牆安裝工作進入尾聲，整體工程預計於今年底正式竣工。

全球最高的混合木構造大樓在雪梨封頂了！這座由 SHoP Architects 和 BVN 聯合設計的 Atlassian 總部大樓，高達 180 公尺，足足比之前的世界紀錄高出快 100 公尺。
整座 39 層樓的大樓非常有意思，是用混凝土核心加上木結構地板，外層再套上一圈鋼骨外骨骼。每四層樓就設有一個高空公園跟挑高中庭，把傳統辦公室變成了垂直的自然棲地。
更讚的是，比起一般鋼筋混凝土大樓，它的碳排放直接減半，而且大量採用預製化木構件，施工速度更快、更輕盈。大樓底下還直接融合了一座由歷史建物改建的青年旅館，預計今年底就會正式完工！

The Atlassian Central skyscraper, designed by SHoP Architects and BVN Architecture, in Sydney, Australia, has become the world's tallest hybrid timber tower.
Designed as the Sydney headquarters for technology company Atlassian, the 180-metre-high office tower topped out earlier this week.
With a hybrid structure of timber, steel and concrete it overtakes the 86.6 -metre-high Ascent tower in Milwaukee, USA, by almost 100 metres, to become the world's tallest hybrid timber tower.
The 39-storey skyscraper has a unique hybrid structural system, with concrete cores supporting mass timber floors and internal structures, wrapped in a steel exoskeleton.
This exoskeleton supports seven "mega floors" that have been placed every four stories to divide the building vertically into what the design team described as "habitats".
These, primarily timber, habitats will contain office accommodation along with multi-floor atriums and elevated parks.
"SHoP has been privileged with the opportunity to design such an innovative project – one that we believe will redefine how people come together, collaborate, and create in Sydney and beyond," said SHoP Architects associate principal Andreia Teixeira.
"It's particularly rewarding to begin experiencing the spatial qualities of a high-rise that reimagines a natural habitat within an urban tower – connecting people to each other, nature and to the city around them," she continued.
"We're excited by how this concept sets a new benchmark for sustainability, where timber, landscape, and natural ventilation come together to shape a more holistic work-life experience and inspire future innovation."
According to the design team, the use of timber has reduced the overall building weight and carbon impact, while the steel and concrete ensures strength and stability.
The design expects the design to reduce the upfront embodied carbon by 50 per cent compared to a conventional steel and concrete office tower.
The team aims to also achieve a 50 per cent improvement in operational energy efficiency compared to a conventional 5 Star NABERS base building.
"Hybrid mass timber has done more than reduce embodied carbon, it has fundamentally shaped how tower buildings can be delivered, enabling prefabrication, dry construction and a faster, lighter vertical build," said BVN principal Peter Titmuss.
"As a prototype for mass-timber towers of the future, this is a moment of global significance."
The tower sits next to Sydney Central Station and was built over an existing historic building called The Parcels Shed that was once used for taking deliveries of parcels and then turned into a youth hostel.
SHoP Architects and BVN plan to incorporate the youth hostel building into the lower levels of the tower.
The project is set to complete by the end of this year with facade installation currently being completed.

New York-based SHoP Architects was founded in 1996.
The practice has completed a series of monumental tower designs including 111 W 57th Street on Billionaires Row in Manhattan and Brooklyn's first supertall skyscraper.
BVN is an Australian architecture firm that has offices in Sydney, Brisbane, London and New York.
