瑞士鳥類研究所的新訪客中心坐落于森帕赫湖畔，臨近盧塞恩。它的目的是向公眾更好地展示鳥類研究所在自然鳥類的研究和保護中所做的工作。

訪客將穿過交織在展覽區和湖畔建筑之間的動態而平衡的步行道。兩個緊湊的多邊形體量是對地段周邊湖區景觀的回應。兩個體量之間的空間形成一個寬敞的門廳，從這里可通往所有展區。門廳盡頭的觀賞鳥籠形成了室內外空間的流暢過渡。

除了展覽空間外，建筑中還包括一座電影院、工作及研討空間、一個為訪問研究者提供的小居住單元。

瑞士鳥類研究所訪客中心是第三座在立面上使用預制夯土構件的大規模項目。這種不會因氣候條件而變化的預制構件帶來了廣泛的好處，例如實地施工的效率提升和時間的縮減。35cm或45cm厚的夯土墻是自承重的，立面背后是承重混凝土框架。

建筑另一個突出特征是使用了考登鋼窗框，它是與夯土立面同時安裝的。窗框和窗戶都錨固在夯土構件之中。□ （黃華青 譯）

The new visitor center of the Swiss ornithological station is situated on the banks of the Sempach Lake, close to Luzern. It is supposed to give the public a better insight to the work of the ornithological station in research and maintenance of the native bird species.

The visitor is guided by a dynamically balanced network of pathways through the exhibition and the lakeside property. The situation of the two compact, polygonal forms refer to the position in the surrounding landscape and the lake. The intermediate space between the two buildings becomes a generous foyer, allowing access to all parts of the exhibition. The show aviary at the end of the foyer forms the fluent transition from the interior to exterior.

In addition to the exhibition space the complex includes a cinema, working and seminar space, and a small living unit for guest researchers.

The Visitor Center of the Swiss Ornithological Institute is already the third large-scale project with a fa?ade made of prefabricated rammed earth elements. A pre-production which is not subject to changes in weather conditions offers a wide range of advantages such as the increase of efficiency and the reduction of the actual construction time on site. The 35 or 45 cm thick walls are self-supporting and stand in front of the load-bearing concrete skeleton structure.

Another extraordinary feature is the Corten steel window frames, which were installed together with the rammed-earth fa?ade. The frames and the windows are both anchored in the rammed earth components.□

評論

穆鈞：與利口樂草藥中心相比，該項目對于外圍護夯土墻在形式、功能、洞口開設等方面提出了更高的要求，而這些通過馬丁團隊日益成熟的預制夯土技術得到了更為從容的回應。根據所在部位的不同，預制夯土單元具有更為多樣的內部強化構造和倒角形式，以滿足多種結構和構造連接的需要。在夯土材料的改良方面，馬丁依然堅持僅利用土砂石級配，而拒絕添加化學改性劑的環保理念，并通過建筑及構造設計的途徑克服或規避材料在力學和耐水性能方面的相對缺陷。例如，夯土墻頂部采用金屬板下彎且輕微挑出的壓頂形式，有效地避免了雨水順流對墻體的破壞；門窗洞口上部直接采用底部配筋的夯土單元作為洞口過梁，而后置的金屬窗套可有效地避免雨水對洞口周邊夯土的侵蝕。在利用夯土材料特性和預制夯土施工技術特點的過程中，自然形成了與之相應的設計語言。

Comments

MU Jun:In comparison to Ricola Kr?uterzentrum, this project has higher requirements for the rammed-earth wall enclosure in terms of forms, functions and openings, which are readily responded to with the increasingly mature rammed earth prefabrication technology from Martin's team. Depending on their locations, prefabricated rammed earth units have diversified internal reinforcement and chamfering forms to meet various structural and tectonic connection requirements. With respect to earthen material enhancement, Martin insists on an environmentalism where only earth and graded sand are used without chemical modifiers. The material's weaknesses in mechanical performance and water resistance are overcome or avoided by means of architectural and tectonic designs. For instance, metal plates that bend downwards with a slight overhang are used at the earthen wall top for capping, which effectively protects the wall from dripping rainwater damage. Rammed-earth units reinforced at the bottom serve as lintels for door and window openings, and mounted metal window surrounds can protect the rammed earth around the openings from rainwater erosion. A design language is spontaneously developed during the process which takes advantages of the earthen material's properties and prefabricated rammed-earth construction technology.
