丹麦法律机构Horten希望他们的新总部采用当代的设计,并有古典建筑的坚实的风格。建筑师提出的方案是用经典的石头材质立面去演绎现代的办公空间。

在内部,建筑采用轻和灵活开放的结构,鼓励内部交流和知识共享。建筑的外观复杂而有动感。

独特的外观成为可持续建筑设计的新标准。玻璃纤维和石灰华的外表皮可遮阳,建筑设计可能源节约。

节约能源的建筑形式

从一开始,建筑设计的目标不仅仅是满足现有的节能要求,而是要超越现有的规范,为节能环保设定新的新标准。

为了防止过热,有必要封闭建筑的南面,而开放建筑的北面。建筑的表皮是三维的,所以有遮阳作用,从而保持办公室温度适宜。同时也让每个办公室朝向水面景观。

换句话说,该建筑的朝向和三维表皮为节能作出了贡献。

新材料

建筑设计是独特的,外观也用了独特的材料。为了制造特殊的表皮几何结构,采用了是自然形式的设计,并使用新建筑材料和建造方法。

如果同一个正面是用传统建造技术(即钢框架结构),这将是一个很大的挑战,由于需要分别建立每个构件,因此很难保持众多构件完全一样。与此相反,采用玻璃纤维就有可能大量生产完全一样的各类建筑构件。

3XN的建筑师和合伙人Bo Boje Larsen说:“我们研究发现的船舶和风车使用了该材料,不过,没有建筑采用自支持的绝缘玻璃纤维材料”。

玻璃纤维具有许多良好的能力,可以被精确的设计和制造,我们的创新是把它用于建筑领域。

最终,外表皮采用了两个玻璃纤维复合材料层,一层高绝缘的泡沫核心,去包裹石灰华。

优化设计

为了保持在预算范围内,有必要让表皮采用尽量少的构件类型并且不损害表皮的独特性。使楼板和立面的锯齿形用合理和有效的方式表达出来。此外,利用模具的同时不影响表达最初的建筑设计方案。

3XN的丰富经验的项目建筑师Olaf Kunert说:“我们看到建成的结果后,并不觉得两年的研究和开发是辛苦的事情。最困难的挑战,也是最有趣的”。

Danish law firm Horten wanted their new headquarters to present itself in a contemporary as well as classical and solid way. Our solution was to design a modern office with a new interpretation of the classical stone-clad facade.

 

Inside, the building appears light and open with a flexible structure encouraging informal meetings and knowledge sharing. The dynamic atmosphere is intensified by the complex and innovative exterior expression.

 

A unique façade design was developed in order to set new standards within sustainable solutions. The three dimensional façade in fiberglass and travertine works as a screen against the sun while still providing a view to the water. In this way, the architecture itself is actually the main contributor to the energy savings of the building.

Shape which saves energy

 

From the start, the objective was to design a building that didn’t just live up to the existing energy saving requirements, but that set new standards in surpassing these environmental regulations in the building code.

 

In order to shield against overheating, it was necessary to design the building in such a way that it is closed to the south and opened to the north. Because of the three dimensional relief, the facade works as a screen against the sun, thus allowing a pleasant office temperature. This is done while still providing a view to the water with each office having its own individually framed ‘bow’.

In other words, it is the architecture itself that has contributed most to energy savings in this building; the building’s orienta- tion and the facade’s three-dimensional self shielding design.

New Materials

 

With its unique design, the facade is also unique in its material composition. To adapt to the special geometry, it was natural to design using new and innovative building materials and methods.

If the same facade was to be built using traditional construction methods (ie. steel frames), it would be a challenge to build each element separately and therefore difficult to keep uniformity. By contrast, by taking the decision to build completely out of fibre- glass, it becomes possible to mass produce with much fewer discrepancies amongst the various building elements.

 

- In our research, we found several relevant references to ships and windmills – but no building projects with self-supporting and insulating fibreglass elements, says Bo Boje Larsen, Architect and Partner in 3XN.

 

The production method using fibreglass has been well known in many capacities, which allows for accurate projections and the know-how to actually design with it. The ‘innovation’ has been integrating fibreglass into building design.

 

The end result is a facade design which consists of two layers of fibreglass composite, with a highly insulated core of foam; upon which is placed an outer layer of travertine.

Optimal Design

 

In order to keep within the budget, it was necessary to design a facade with as many repetitions as possible without losing the unique expression of the building. Making the floor slab design zig-zag shaped allows for a very rational and efficient way of attaching the facade. In addition, by making optimal use of the moulds, it is made possible to realize the complex geometry without compromising the original architectural vision.

 

- Two years of research and development doesn’t really feel like hard work when we begin to see the results take form. The hardest challenges have actually been the most fun. In fact, it is these challenges that enrich the experience of an architect, says Olaf Kunert, an Architect on the project at 3XN.
