社保办公大楼，比利时 / WAW architects

2008年，WAW赢得了由OCMW Halle和Flemish Government Architect组织的建筑竞赛。该项目旨在通过最低限度的空间介入，令这栋始于1900年代的Old Orphanage众多外部历史特性得以保留。

应客户要求，全新的Social Welfare Office需与相邻的OCMW场地之间建立良好的视觉联系。为实现这一目标，设计师在新大楼右侧毗邻停车场和OCMW的建筑立面嵌入全新的公共出入口，悬挑于新入口之上的附加结构是建筑最引人注目的部分，时刻提醒着人们入口的所在，该部分体量被用作多功能会议室。

原有的临街建筑入口被保留，但如今它仅作为仪式性的出入口存在，从此处进入，来访者也可抵达前侧会议室。

In 2008, WAW won the architectural competition organized by the OCMW Halle and the Flemish Government Architect. The aim of the project is to preserve the historical character of the “Old Orphanage” from the beginning of 1900 on the outside and to realize a minimal addition.

The client asked for a visual connection between the new “Social Welfare Office” and the adjacent OCMW site. This was solved by situating the new public entrance on the right side, adjacent to the parking and the OCMW site. This public entrance is indicated by the new volume on columns that has been installed in front of the existing rightside facade. The new glazed volume accommodates the multipurpose meeting room and acts as a portal to the Social Welfare Office.

The old entrance on the street side was retained, but today it only serves as a ceremonial entrance, but can also be used as a separate access to the meeting rooms in the front.

▼建筑外貌，exterior view

设计师在原有的封闭的建筑立面上开设两个巨型飘窗。它们分设建筑左右两侧，时刻向街道上的行人展示建筑的内部风采。行人可以直观且清晰的窥视到内部空间，而身处飘窗之内的人们，也可以一览林荫大道上的静谧景观。

In the originally closed side facades of the old building, new glazed bay windows were realized both on the left and on the right as a display case, and they announce the Social Welfare Office from the street.

From the street, these are clearly visible and give you a view through the building. From the interior, the users have a pleasant perspective on the avenue.

材料

Materials

附加的建筑部分采用了混凝土和玻璃作为基本材料。除用拉伸钢材作为第二条紧急逃生楼梯的外部结构外，设计师还用这一材料对原建筑中建造于60年代的电梯井进行加固与装饰，以彰显这两部分的不同。

In terms of materials for the new elements, especially visible concrete and glass was used. In addition, we used stretch steel for the coating of the 2nd emergency stairs outside, but also for the upholstery of the old elevator shaft built in the 60’s, to show that this does not belong to the original building.

程序 Program

底层入口设置在两栋建筑的十字交叉口处，因此，设计师顺势在交叉口处设置的接待及等候大厅。原建筑昏暗的半地下室空间被彻底转变成通透、明亮、可达性良好的建筑首层，来访者在此处获得接待、会面或短暂洽谈。

接待处与等候区的上层空间充分开放，且上下两层拥有良好的视觉联系，让来访者可以轻易观察到楼上的办公情况。

The entrance on the ground floor is situated on the junction of the cross-shaped building. This junction is arranged as a reception and waiting area.

The formerly dark and half underground level was transformed into a fully accessible, open and airy ground floor where the public area is situated with reception and meeting rooms.

At the height of the waiting area, the floor on the first floor was opened so that the reception and waiting area had visual connections with the offices and the meeting rooms on the first floor.

除接待处，会议室和办公室外，该建筑还包括一系列开放接待和讨论空间，一座位于二层的小型礼拜堂及一间档案室。

客户希望将这栋Old Orphanage改造成具有开放性的Social Welfare Office办公大楼。按此要求，设计师对现有结构进行彻底拆除，并在建筑内部营造了一系列空间，贯通了内部视线，同时赋予其挑高的天花板和通透的内部隔墙。

建筑内部各层尽可能充分开放，以实现内部办公区域的最大灵活性，适应了未来的多种使用需求。

In addition to a reception, meeting rooms and offices, the Social Welfare Office program also includes open talk rooms for reception of the public, an existing chapel on the 2nd floor and an archive room. The client asked for the “Old Orphanage” to be transformed into an ‘open “Social Welfare Office”. This was realized by completely breaking down the existing internal structures, creating voids, realizing views and maintaining the existing levels with their high ceilings and high windows on the inside.

Each level was opened as completely as possible without inner walls, so that the offices can be arranged as freely as possible and remain as versatile as possible in the future.

位于一二三层的办公空间维持开放的特性，只有部门主管的办公空间拥有封闭的玻璃围墙。

新嵌入的多功能会议厅两边设有休息室和小厨房，而同样位于二层并与之相邻的礼拜堂，则被改造为OCMW委员会议会厅。

礼拜堂的氛围是封闭而亲密的，而多功能会议厅的氛围则恰恰相反。

与其他办公大楼不同，该建筑的档案室并没有设置在地下层或地面层，而是位于阁楼顶层。

The offices on the 1st, 2nd and 3rd floors were left largely open. Only the department heads have a glazed lockable working space.

On the second floor, next to the existing chapel, the new multipurpose meeting room was planted around a foyer & kitchenette. The chapel is set up as the new council chamber for the OCMW. Where the chapel has a closed, intimate character, the new meeting room is the opposite.

The archive was not housed on the ground floor or in a basement, but at the very top of the attic space.

结构

此次改建仅保留了建筑的外貌，在内部嵌入了全新的柱式和楼板。并尽最大可能将混凝土结构、天花板和柱式暴露在来访者面前。与此同时，附加于三层两侧，用于支撑四层档案室的钢结构也被暴露在外。

新置入的多功能会议室外立面全部由玻璃幕墙铺设。这一外立面的结构设计灵感来自于礼拜堂的玻璃花窗。礼拜堂的花窗拥有钻石的形状，而这间多功能厅的玻璃幕墙、天花板和隔音墙恰好映射了这一钻石形状。位于天花板上的圆形凹槽则是为了节省对混凝土材料的使用。

Only the outside volume of the building was retained. A new structure of columns and plates was installed inside the building. The aim was to make the new concrete structures, ceilings and columns in concrete as visible as possible. The new steel structures were also left visible, such as those for both side tasks on the 3rd floor and the new steel structures for accommodating the roof in the archive on the 4th floor.

The façade cladding of the conference room on columns next to it is completely covered in glass. For the structure of the glazing we were inspired by the stained-glass windows of the chapel. These have a diamond shape. Both the glazing, the structure and the acoustic wall covering of the conference room refer to this diamond shape.

The circular recesses in the concrete ceiling of the conference room mean that less concrete is required.

技术 Techniques

地板、墙面和屋顶的隔热特性帮助建筑实现了节能效应。外墙内侧的的隔热性使外侧的历史性外貌得到保留。由于礼拜堂玻璃彩窗与内部细节的种种限制，使得建筑外墙的隔热性难以实现。因此，设计师在彩窗外侧附加一层玻璃窗面以提供更好的保温与保护效果。

建筑由低温地暖系统来维持室内温度恒定，极好得适应了高天花板和夹层的对流空间。为了避免室内温度过高，建筑南侧窗面及部分内部空间设有遮阳百叶和调光玻璃窗。

收集自屋顶的雨水可用于冲刷马桶及花园灌溉。

To make the building energy-efficient, floors, walls and roofs were insulated. The outer walls were insulated on the inside of the building, given the historical character of the outer shell. In the chapel it was not possible to use inner insulation for the sake of detailing and connection to the stained-glass windows. The stained-glass windows were provided on the outside with front windows to protect them from the weather conditions.

The building is heated with underfloor heating at low temperature, ideal for high rooms and additional floor convectors. In order to prevent overheating, external sun blinds were installed on the south side and indoor blinds in other places, including solar control glazing.

The rainwater from the roofs is collected and reused for flushing the toilets, cleaning and the garden.

声效

Acoustics

一个开放的建筑空间对隔音效果有严格的要求。开敞的办公室和会议室的天花板均安装了隔音板，此外办公室内部还特别安装了带有滑动隔音板的家具。

在大型多功能会议室中，两个隔音板采用方格形图案，呼应了礼拜堂和多功能会议室的花窗。除集成照明系统外，多功能厅的内凹混凝土天花板内还嵌入圆形隔音板。

An open building requires special attention for the acoustics. The landscape offices and the meeting rooms are equipped with acoustic panels on the ceilings. In addition, the offices were fitted with furniture with acoustic sliding panels.

In the large multipurpose meeting room 2 acoustic walls were realized in a checkered pattern. This checkered pattern can be found in the glazed facades and the stained-glass windows of the chapel. In the recessed circles of the concrete ceiling of the meeting room, in addition to the integrated lighting, also provide round acoustic panels.

色彩

Color

除了维持建筑的朴素特性外，设计师也希望为其装点一些特别的色彩。因此，建筑内各层都嵌入了一些有不同颜色点缀的特殊区域，颜色出众的厨房和固定家具为这些空间增色不少。

In addition to the pursuit of austerity, we did want to apply some color accents. Here and there a different color was used per level for the fixed furniture and the kitchens each received a different striking color.

修复 Restauration

此次改造充分尊重了建筑的历史。其中建筑外貌得到了全面保留，室内装饰、细部节点和蓝石构件得到了修护，天然石板材料让屋顶焕然一新。

位于礼拜堂之上的原有屋顶塔楼被移除，并近乎由全新的结构所替代。依照原塔楼风格打造的木质窗框分布与新结构表面，以呼应该建筑的历史性。

原建筑入口大厅内的水泥砖和大理石台阶被重新利用，天花板挂线盒装饰被重新修复。二层礼拜堂的木质拱顶、玻璃窗面和水泥花砖地板被保留和修复，翻修结束后，位于室内的祭坛又被重新挪入该空间里。

It was renovated with respect for the historic building. The outer shell was completely restored. Repair of the parement, the jointing, the blue stone elements, renewal of the roofing with natural slates. The rooftower above the chapel was removed and almost completely replaced by a new to original model.

New wooden windows were placed according to the original model to preserve the character of the historic building. In the old entrance hall the old cement tiles and the marble steps were reused and the ceiling rose was reintegrated.

In the chapel on the 2nd floor the old wooden vault, the stained glass window was preserved and restored. The altar room and floor with colored cement tiles were retained, and the altar furniture was dismantled during the construction and then returned.

环境规划

Environmental planning

场地拥有一个24车位停车场，一个自行车停车处以及位于场地后身的无障碍专用停车位。预留的雨水缓冲水槽为生态环流和雨水径流做出了贡献。

A parking space for 24 vehicles, a bicycle parking space and additional parking spaces for disabled people were realized at the back of the site.

In the garden, a WADI is constructed as a buffer basin, to catch the rainwater flowing from the sloping garden and the parking lot in the event of heavy thunderstorms.
