多层办公：大型木桁架结构设计

柏林EDGE Suedkreuz的七层办公大楼是采用以可持续方式建造的。两座独立建筑中较大的一座占地约20000平方米，是德国木材混合建筑。德国可持续建筑委员会（DGNB）在2022年将该项目认证为德国最可持续的建筑。

The seven-story office complex EDGE Suedkreuz Berlin was built sustainably using a modular timber hybrid construction method. The larger of the two free-standing buildings covers around 20,000 sqm of floor space, making it the largest wood-hybrid building in Germany. The German Sustainable Building Council (DGNB) certified the project as Germany's most sustainable building in 2022.

在卡雷的中心，建筑是一个宽敞的、光照充足的中庭，由一个透明的ETFE铝箔屋顶横跨在木桁架结构上。吸引人眼球的是四个树状结构，高度不等，其平台通过丝状楼梯和桥梁相互连接，并与办公楼层相连。在五楼，拥有全景外墙和室外露台的天空休息室向中庭开放。木材明显地出现在建筑的所有内部区域。

At the heart of the Carré, the building is a spacious, light-flooded atrium, spanned by a transparent ETFE foil roof resting on a wooden truss construction. The central eye-catchers are the four tree-like structures, graduated in height, whose platforms are connected to each other and to the office floors by filigree staircases and bridges. On the fifth floor, the Sky Lounge with its panoramic facade and outdoor terrace opens up to the atrium. Wood is visibly present in all interior areas of the building.

在建筑施工中，重点是尽可能地减少二氧化碳排放量和建筑群的重量，并根据 "从摇篮到摇篮 "的原则，使用可以回收的可持续材料。该项目已在Madaster数据库中注册，并有一个材料护照，使所使用的材料能够被重新使用和回收。

由于与传统的现浇混凝土施工相比，钢筋混凝土节省了约50%，因此该建筑群与施工有关的二氧化碳足迹也相应地降低。工业化的预生产（包括轻质外墙）和木材的使用是必不可少的建筑材料。建筑重量低、外壳施工时间短、规划和成本安全性高、耐用性长是这种建筑的进一步优势。

In the construction of the buildings, the focus was on reducing the CO2 footprint and the weight of the complex as much as possible, and on using sustainable materials that can be recycled according to the cradle-to-cradle principle. The project is registered in the Madaster database and has a material passport that enables the materials used to be reused and recycled. Due to an approx. 50% saving of reinforced concrete compared to conventional in-situ concrete construction, the construction-related CO2 footprint of the ensemble is correspondingly lower. Industrial pre-production (also of the lightweight facades) and the use of wood were essential building blocks. A low construction weight, shorter shell construction times, high planning and cost security, and long durability are further advantages of this construction.

外墙是由每平方米仅重30公斤的耐候性玻璃纤维混凝土板组成的均匀网格。由于其特殊的表面结构，它们约有80%可回收利用，并具有脱碳效应。

The facades are constructed in an even grid of weather-resistant glass-fiber concrete panels that weigh only 30 kg per sqm. They are approx. 80% recyclable and have a decarbonizing effect due to their special surface structure.

通过广泛的解构概念，循环性问题在很早的阶段就被纳入了规划。建筑的灵活性和可重复使用性得到了保证，除其他外，避免了室内承重墙，房间高度至少为3米，楼梯的安排经过深思熟虑，以及建筑技术设备的分区。办公楼的平面图是基于一个灵活的、模块化的网格。

With an extensive deconstruction concept, the issue of circularity was integrated into the planning at a very early stage. The flexibility and reusability of the building are ensured, among other things, by avoiding load-bearing interior walls, a room height of at least 3 m, a well-thought-out arrangement of the staircases, and the zoning of the technical building equipment. The office floor plans are based on a flexible, modular grid.

该建筑能源供应的四个主要支柱是充足、高效、热电联产和负荷管理。在这个过程中，创造了一些条件，使用户对有意识地、有效地使用能源产生敏感。办公空间的空调是由智能吊顶提供的。办公室内充足的日光将对人工照明的需求降至最低。

The four main pillars of the building's energy supply are sufficiency, efficiency, combined heat and power, and load management. In the process, conditions were created to sensitize the users to a conscious, efficient use of energy. The office spaces are air-conditioned by suspended smart ceilings. A sufficient amount of daylight in the offices minimizes the need for artificial lighting.

办公区以及相关的辅助区和流通区都是无障碍的，所有的室外区域也都设计成无障碍的。柏林EDGE Suedkreuz获得了DGNB白金证书，其得分是德国有史以来最高的95.4%。此外，由于其出色的设计和建筑质量，该建筑群还获得了DGNB钻石认证。同时还在争取获得WELL v2白金认证。

The office areas as well as the associated ancillary and circulation areas are barrier-free, and all outdoor areas are also designed to be accessible. EDGE Suedkreuz Berlin received the DGNB Platinum certificate with the highest sc ore ever achieved in Germany of 95.4%. In addition, the ensemble was certified with DGNB Diamond for its outstanding design and architectural quality. WELL v2 Platinum certification is also being pursued.
