開放、簡潔、可持續、以人為本，這些關鍵詞描繪了安娜圖拉工作園區的新建建筑。

達姆施塔特市的安娜圖拉工作園區在可持續性、材料效率、開放性和辦公樓的新工作方式等方面達到了一個建筑里程碑。由haascookzemmrich STUDIO2050設計的安娜圖拉新總部建筑獨具特點，例如采用創新的夯土外墻，以及這是世界上第一個墻身加熱供暖的建成實例。

這座前美國陸軍凱利軍營所在地的建筑物幾乎不會讓人聯想到傳統的辦公大樓，其在3層樓約10,000 m2的空間內為500名員工提供了工作場所。

主要的設計目標從一開始就是使建筑物實現全年自然通風，避免頻繁地消耗和維護暖通空調系統。向西的森林為這個想法提供了理想的條件。

安娜圖拉工作園區的新鮮空氣被兩個進氣塔吸入地下通道，并在建筑物內擴散開。由接地管道提供的預調節空氣，將加熱和冷卻的額外能源需求降至最低。

安娜圖拉工作園區的設計探索了許多新設計方式。規劃團隊不僅評估了運營該建筑所需的能源，還對其施工、維護，甚至最終拆除所需的所有資源都進行了嚴格審查，無一例外。

這種新的整體方法堪稱范例，并得到了德國聯邦環境基金會（DBU）和慕尼黑工業大學的資助。安娜圖拉總部大樓的早期設計過程中就對能耗進行了分析，從而為單個組件開發了節能解決方案。

主創團隊與馬丁·勞奇和Transsolar公司一起開發了一種創新的帶有墻熱供暖系統的夯土立面。夯土塊被堆砌在南北外墻上。

生產、加工甚至移除夯實土塊的過程中幾乎不會產生能耗。由于該材料的耐久性及土壤在濕度調節和蓄熱能力方面的優異性能，該建筑將長期保持其價值。由于表面不會有藻類或苔蘚生長，因此無需對立面進行清潔之類的工作。對建筑內部，多孔表面不僅有助于改善室內氣候，而且有助于改善相鄰辦公區的聲學性能。□

Words such as open, simple, sustainable, and people-orientated describes the newly constucted building of Alnatura Arbeitswelt.

Alnatura Arbeitswelt in the city of Darmstadt has reached an architectural milestone in terms of sustainability, material efficiency, openness, and new ways of working in an office building. The building at Alnatura Headquarter, designed by haascookzemmrich STUDIO2050, offers special features such as the use of an innovative rammed-earth fa?ade and it is the first worldwide instance of using geothermal wall heating.

The building on the site of the former USArmy Kelley Barracks hardly brings to mind a conventional office building and offers space for up to 500 employees on three floors with a floor area of approximately 10,000m2.

From the very beginning a key design objective had been to achieve natural ventilation in the building throughout the year and to avoid resource and maintenance intensive HVAC systems. The forest towards west provided ideal conditions for this.

Fresh air for the Alnatura Arbeitswelt is drawn into a subterranean channel by two air intake towers and distributed through the building. Thanks to the pre-conditioned air supplied by the earth duct, the need for additional heating and cooling is reduced to a minimum.

The design of the Alnatura Arbeitswelt explored many new design avenues. Not only did the planning team assess the energy that would be needed to operate the building, they critically reviewed all resources required for its construction, upkeep, and eventual demolition and removal without exception.

This new holistic approach was regarded as exemplary and received funding from the German Federal Environmental Foundation (DBU) and the Technical University of Munich. The analysis of grey energy early on in the design process of the Alnatura Headquarter permitted the development of energy- efficient solutions for individual components.

An innovative rammed earth fa?ade with a geothermal wall heating system was developed together with Martin Rauch and Transsolar. Rammed earth blocks were stacked along the northern and southern fa?ades.

Almost no grey energy is required for the production, processing and potentially removal of rammed earth. Thanks to the durability of the material as well as the excellent properties of loam in terms of humidity regulation and thermal storage capacity, the building will preserve its value over a long period of time. As no algal or mossy growth occurs on the surface no cleaning or similar work needs to be performed on the fa?ade. Inside the building, the porous surfaces help improve not only the indoor climate, but also the acoustic performance of the adjoining office area.□

評論

藍冰可：安娜圖拉的新總部建筑，采用高標準一體化的綠色建筑設計策略，同時營造以人為本、以員工為中心的辦公空間氛圍，很好地詮釋了其崇尚自然可持續性的企業形象。一個能容納500人的縱向連續的景觀式辦公空間位于建筑的中心，在天井自然采光的沐浴下，促進員工間的溝通與互動自然而然地發生，激發員工的靈感與創造性。而建筑靠近外圍的區域，則是更加密集但不失靈活性的集中辦公空間。設計師利用家具的布置與窗簾隔斷的設計為空間進行靈活的劃分，以滿足日常工作中對于不同空間品質的多樣化需求，充分體現設計師對于新型工作模式的解讀與回應。

葉揚：安娜圖拉總部大樓的建筑師，用謙遜到不易察覺的方式極具創造性地解決了這類項目容易出現的困境：一個大型連通空間如何在為許多人服務的同時確保開放性與舒適度。設計提升了空間品質，關注了人與人在工作中獨處、交流、交往、共享的需求，光環境、空氣流通的處理都實用而怡人。最特別的是，設計將材料和結構與熱環境和節能結合在一起進行考慮。夯土外墻在環境中發揮的作用具有建筑學意義上的啟發性。它為更多的城市建筑提供了新的解決方案。

Comments

Binke Lenhardt: The Alnatura new headquarter represents the company image with its sustainable strategies in a strong holistic quality, applying high ecological standards in line with an employee centred design approach. An open office landscape for up to 500 employees, extending over a multi-levelled middle sky-lit atrium nurtures natural communication, interaction and enhances creativity. The more concentrated but flexible work zones, defined by furniture and curtains that spread from the atrium to the perimetre of the building provide a wide range of spatial variations for different work dynamics and represent a good model for the future of workspaces.

YE Yang: The dilemma which this type of projects usually faces is how a large-scale continuous space maintains its openness and comfort while meets needs from lots of people. Architects of Alnatura Headquarter solved it through their humble, subtle yet extremely creative approach. The quality of space was upgraded by addressing the requirements of independent work, communication, social connection and sharing among people. Lighting and ventilation utilised are practical and appropriate. It is very unique that the combination of materials and structures considered thermal environment and energy saving. It is architecturally inspiring in that rammed earth external wall plays its role in the environment, which provides a new solution for more urban buildings. (Translated by PANG Lingbo)
