· 柏林南十字附近的两座七层建筑展示了大规模木建筑的潜力；

· EDGE是目前德国规模最大，也是欧洲最大的独立式混合木建筑之一；

· 在该项目的结构工程、建筑服务和可持续性方面，Buro Happold树立了使用可再生及可持续材料致力于碳中和的全新标准。

柏林南十字EDGE大楼为木建筑打造了可持续的未来新愿景。该项目由Carré和Solitaire两座建筑组成，其中前者体量更大。建筑位于柏林主要的交通枢纽南十字车站对面，采用了木柱和预制木材混合板的模块化木材及混凝土系统建造，是可持续性与宜居性相融合的城市发展新项目的一部分。

Carré大楼是Vattenfall能源公司的办公空间。作为建筑的中心，高耸的木格天窗下的中庭面积达1600平方米。四根形似树干和树冠的大柱子点缀其中，为楼梯和上层的人行道系统提供支撑。屋顶由木材、钢材和轻型四氟乙烯（ETFE）垫构成，调节温度的同时过滤进入中庭和周围办公空间的光线，在不同的气候下提供温暖、舒适的工作环境。位于建筑五层的实木凉廊，由高1.5米的桁架和交叉层压木天花板构成。

可持续发展的整体方法在EDGE项目之初便成为了开发的关键。这种方式降低了建造过程的碳排放和建筑周期内的碳足迹，并对用户的福祉给予了细致的考量。项目将以木材为主和模块化建造方法相结合，这两项对打造大尺度的可持续建筑至关重要。TCHOBAN VOSS建筑事务所和Buro Happold与木材模块系统的开发者CREE Buildings充分合作，CREE Buildings是一家总部位于奥地利多恩比恩，专门打造混合木材建筑的公司。混合木结构的重量比标准结构轻50%，从而降低了对地基的要求。

EDGE项目在德国可持续建筑委员会（DGNB）总体合规评级中获得了超过95.4%的评分，成为德国最可持续的建筑项目，并因其设计水准荣获了DGNB的钻石奖荣誉，这一认可有力证明了项目注重可持续开发和用户福祉的整体战略的成功实施。

柏林Buro Happold的联合董事Martin Elze强调了EDGE的建成对混合木建筑未来发展的重要意义：“EDGE的模块化木结构从根本上减少了结构支撑所需的混凝土数量，并提供了可行的、可扩展的可持续建筑替代方案。该项目展示了可持续建筑行业在应对气候危机的众多措施的一项。”

TCHOBAN VOSS建筑事务所的合伙人Sergei Tchoban表示：“EDGE不仅是一个建筑群。对我来说，这个项目将持续作为一种新思维模式的原型。建筑建造的重点是尽可能减轻重量，从而减少碳足迹，并将建筑美学和我们对自然的责任感相结合。我们特别采用了以“从摇篮到摇篮”原则回收的材料，建筑构件的预制及能够重复使用的特质确保了建筑系统的可持续性，为营造令人印象深刻的建筑空间和面向未来的工作环境提供可能。

· Two seven-storey buildings near Berlin's major Südkreuz train station demonstrate the potential of large-scale timber construction.

· EDGE Suedkreuz Berlin is the largest freestanding wood-hybrid project in Germany and one of the largest in Europe.

· Buro Happold's work on structural engineering, building services and sustainability for the project proposes a new standard for working towards carbon neutrality with renewable and sustainable materials.

EDGE Suedkreuz Berlin offers a new vision of a sustainable future for construction with timber. The project consists of two buildings: the larger Carré and the smaller Solitaire. A modular wood and concrete system was used for construction, comprising timber columns and prefabricated timber- hybrid slab panels. Located opposite the Südkreuz station, one of Berlin's major transport hubs, the project is part of a new urban development that integrates sustainability with livability.

The Carré building houses office spaces for the energy company Vattenfall. An atrium forms the heart of the building and contains 1,600 square metres of space under a soaring timber-lattice skylight roof. The atrium is punctuated by four large columns that mimic the trunk and canopy form of a tree and support a network of staircases and upper-level walkways. The roof is constructed from timber, steel and lightweight ETFE cushions that regulate temperature and filter daylight into the atrium and the surrounding offices, creating a warm, comfortable working environment in all seasons. The building's fifth floor features a solid wood loggia, supported by 1.5-metre-high trusses and a cross-laminated timber ceiling.

A holistic approach to sustainability was key to the development of EDGE Suedkreuz Berlin from the very beginning. This approach encompassed a reduction of the upfront carbon costs involved in construction and in the building's overall footprint, as well as careful consideration of the well- being of users. The project combines modular construction with a reliance on timber, two elements that are essential to building sustainably at a large scale. TCHOBAN VOSS Architekten and Buro Happold worked with a modular timber system developed by CREE Buildings, a firm specializing in wood-hybrid construction based in Dornbirn, Austria. The use of this system means that the timber-hybrid structure weighs as much as 50% less than a standard structure, which kept the foundation requirements low.

EDGE Suedkreuz Berlin received an overall DGNB compliance rating of 95.4%, making it the most sustainable architecture project in Germany. It also received the DGNB Diamond award for design quality. This recognition confirms the successful implementation of the holistic strategy of sustainability and well-being.

Martin Elze, Associate Director, Buro Happold, Berlin, emphasizes the implications of EDGE Suedkreuz Berlin's completion for the future of wood-hybrid construction: “The modular timber construction of EDGE Suedkreuz Berlin radically reduces the amount of concrete necessary for structural support and offers a viable, scalable alternative for building sustainably. The project demonstrates one of various possible responses for the AEC industry to climate emergency.”

Sergei Tchoban, Partner, TCHOBAN VOSS Architekten, "EDGE Suedkreuz Berlin is not just an ensemble of buildings. For me, the project is and remains a prototype of a new way of thinking. In the construction of the buildings, the focus was on reducing the weight and thus the CO2 footprint as much as possible, while at the same time combining the aesthetics of the building with an ethical approach to nature. Special emphasis was placed on using materials that can be recycled according to the cradle-to-cradle principle. The prefabrication of the building components and their possible repeated use ensure a sustainable building system that makes it possible to create impressive spaces and future-oriented working environments."
