安特卫普省政府大楼 / XDGA

设计单位  Xaveer De Geyter Architects

项目地点  比利时安特卫普

建成时间  2019年

建设面积  33,000平方米

新建筑取代了曾经占据整个场地的现代主义建筑群。原有的建筑含有大量石棉[1]，无法适应当今的可持续发展标准，于2013年被拆除。由于安特卫普市中心几乎没有公共绿地，因此充分利用原本被地上停车场占据的面积，将场地从限制公众进入的、纯基础设施向的区域改造成公共花园，是竞赛任务书中的关键要求。

The new building replaces a complex of modernist building volumes that used to occupy the entire site and that could not be adapted to today’s sustainability standards. As the Antwerp city centre has few public green surfaces, the transformation of the site from a merely private, mineral and infrastructural area into a public garden is a crucial requirement of the competition brief.

项目地块周围分布着零散的公共绿地，因此这里对于形成更广阔、更连贯的公园景观，是关键一环。设计任务中另一个略有矛盾的要求是：保留一个建成年代较近的展馆。这个展馆坐落在零散绿地之间，阻碍了公园景观的连续性。

Surrounded by fragments of public green, the parcel is key to the formation of a larger, coherent park. Another – contradictory - demand was to maintain a more recent representational pavillion, which was positioned as an obstacle in between the fragments.

设计将整个项目集成到一个紧凑的建筑体量中，并让这个体量从上方跨过保留的展馆。建筑的正面被切开，主入口设置在与街道相邻的地方。这个大体量将景观空间分为前、后两部分。

By situating the full program in a compact volume across the pavilion, this frontage is cut up and the main entrance is brought close to the street.  This large volume, however, divides the park in a front and a back garden.

设计将体量的上部绕着平面的一角旋转，让建筑朝向市中心，这一操作同时尊重了周边的现有建筑，并生成雕塑般的形态。在设计过程中，展馆建筑最终被一个玻璃体量所取代，以容纳会议和展览功能。

Finally, by rotating the plan around one of its corners as it climbs up, the building shifts towards the centre; existing neighbouring buildings are respected and a sculptural form emerges. During the design process the pavillion building is at last replaced by a glazed volume to house the congress and exhibition part of the programme.

这座建筑被设想为一座横跨展馆的桥梁结构。在建筑平面的中心，一个巨大的钢桁架从一个核心筒横跨到另一个核心筒。另外两个桁架集成在混凝土侧墙上，它们的三角形定义了窗户开口的形式。

The building is conceived as a bridge structure over and across the pavillion. At the center of the plan one large steel truss spans from one core to the other. Two more trusses are integrated in the concrete side walls and their triangulation defines the form of the window openings.

这种三角形开窗进而被应用于整个建筑的表面，因为它有助于在自然采光和防止过多热辐射之间取得理想的平衡。不透明的外墙由白色玻璃马赛克覆盖，而展馆则是绿地中一个完全透明的盒子。

In a next step this window form is applied all over the building as it turns out to be very efficient when it comes to an ideal balance between daylight access and overheating by the sun. The opaque façade is clad in circular, white glass mosaic while the pavilion is a fully transparent box in the park.
