垂直校园 | A vertical campus

EDF学习中心位于巴黎南部的萨克莱高原上，将容纳约16万名发电设施雇员在此进行一到五天的职业学习。该建筑远离员工们通常的工作地点，为他们提供了学习训练的机会，让他们通过会面和相互交流提升自身的活力，同时巩固共同的文化知识。为了满足课程学习的需要，建筑中包含数个接待区，社交集会空间，休息室甚至卧室等，让学员们在每天24小时的学习生活中可以进行丰富多样的活动。美式校园在这座独栋建筑中以垂直的方式得到了再诠释，多功能空间让人们聚集在一起，促进彼此间的交流，以获得更好的学习成果。

The EDF learning center is located at the Saclay plateau in southern Paris. It is intended to welcome some of the 160,000 employees of the electricity generating utility for a stay of one to five days as part of their continuing in house on the job learning. This retreat on the Saclay plateau, sometimes far from an employee’s usual place of work, is an opportunity for staff to learn and train, but also to meet, exchange and re-energize themselves in order to consolidate a common culture. On top of the spaces reserved for learning courses there are reception areas, social life gathering spaces, relaxing lounges and even bedrooms: a variety of programs that together contribute to the exceptional chronotopy of an atypical 24 hours per day operation. The idea of an American style campus is reinterpreted here vertically in this unitary building that is bringing people together in multi-functional spaces which is highly ambitious in terms of getting people to mix with others with dense, proven corollary.

从大熔炉到社会等级制度 | From melting pot to social hierarchy

EDF校园刚刚建成于萨克莱高原的帕莱索地区，与著名的巴黎综合理工学院共属一个片区。

ECDM的设计打破传统的水平布局，在垂直方向上设置建筑的不同功能，从众多竞标作品中脱颖而出，获得竞赛优胜。建筑师将多种功能交织在重叠的楼层中，形成了一个功能丰富的高密度体块，且避免了对周边景观的侵占。空间的私密度从底层的公共区到上层围合成中央露台的亲密区逐级递升，位于入口前厅处的展览大厅和后侧的训练厅独立于该等级区域设置。

The EDF campus has just been set up on the Saclay plateau in Palaiseau, in the same neighborhood as the prestigious École polytechnique.

The prize winning ECDM proposition is marked out from others by the way it is programme is distributed vertically rather than by its plan horizontally. The program interweaves in superimposed layers to develop in a compact volume that absorbs the density of the programming without extending over the surrounding landscape. The space is graded from the bottom to the top to go from the public to the intimate in a parallelepiped volume dug out of a central patio. Only the exhibition hall which stands at the entrance of the forecourt and the training hall at the rear are separate from this.

建筑的立面被区分为三层，分别由混凝土加不锈钢、玻璃和混凝土构成，反映内部功能的同时，形成富有韵味的分层图案，向人们展示了建筑真正的魅力。细长的窗户通过极端精密的框架镶嵌在Ductal®棕色混凝土墙壁中，最上方两个楼层的立面由同样高性能的钢筋混凝土纤维围合，其中分布有270个房间。建筑的立面根据功能类型以1.35米为单位划分，展现出项目鲜明的图案概念。

The facades of the building reveal the program which is divided into three layers distinguished by their covering (concrete + stainless steel, glass, concrete) but also by the rhythm of their piercing which forms a motif of identity, the real thread of the project. The formation stages of the elongated windows are extremely fine frame and are combined with brown Ductal® concrete. The same high- performance fiber of reinforced concrete surrounds the some 270 rooms that span the top two levels. Following a rigorous thread of 1.35 meters, the facades incline according to the typology of the program. In this way another of the strong ideas in the project, its pattern, is revealed.

在两层混凝土立面之间由折线形玻璃板围合出了一个由公共到私密的过渡空间，其中设有餐厅和休闲区域。建筑底层还采用了不锈钢和玻璃材料，作为立面的第三个层次，划分出建筑入口，前部的展览室和后侧的技术大厅。前后突出的两个体块将游客引入到位于建筑中央的公共空间，周边环境在玻璃立面的影响下呈现出万花筒般丰富的形态，以多变的颜色回应相邻的由弧形玻璃墙面围合的EDF研究与发展中心。

Between these two layers of concrete, a pleated glass panel marks a transition from public to private to the intermediate level which houses the restaurant and relaxation areas. At the foot of the building, two other materials, stainless steel and glass, are grafted to these three strata to envelop the technical hall at the back, the showroom at the front and the entrance to the building.These two excrescences invite visitors to enter the public spaces of the central volume, while reflecting their environment in a kaleidoscope of shapes, landscapes and bodies, whose kinetic iridescence is a nod and wink to the neighbor EDF’s research and development center whose circular walls are glazed.

景观中的景观 | Landscape within a landscape

EDF校园位于萨克莱高原巴黎综合理工学院地区边缘，视线所及之处尽是美好的自然风光。为了在不过分控制的情况下对丰富的自然资源进行管理，ECDM通过框景、全景和遮盖等手段设计了多种多样的景观序列，使景色不间断地以不同形式展现在人们面前。项目的景观由Pascal Cribier设计，学习中心和EDF实验室的分享花园是其最近的设计成果之一。

Nature, sky, light spread out as far as the eye can see. Welcome to Saclay plateau and the EDF campus, which enjoys a privileged position on the edge of the École polytechnique district. So which is the best way to manage all this abundance while at the same time avoiding a sense of overkill. The ecdm project puts this landscape on a kind of stage, organizes its appearance and its disappearance by framed views, panoramas, masks — with so many sequences it becomes a kind of show in perpetual transition. This work on the landscape was carried out with Pascal Cribier whose shared garden with the learning center and the EDF Lab is one of his latest achievements.

定制建筑 | Made to measure building

EDF校园属于EDF先锋派传统下长期工业化楼房建造的一部分，设计师与水泥巨头Lafarge Holcim共同对建筑的施工过程，尤其是先进的Ductal®混凝土材料的使用进行了研究，最终建成了这栋与众不同的建筑。

建筑还采用了ECDM在之前的项目中使用过的工业加工方法，如加衬混凝土甚至家具和木工产品等，它们都由供应商名单内的厂家定制而成。

The EDF campus is part of a long line of industrial buildings in the avant-garde tradition of EDF. It is the result of research conducted with the industrialist Lafarge Holcim on prefabrication processes and in particular the projection of its flagship material, Ductal®.

It invokes other industrial processes implemented by ecdm in previous works, such as cushioned concrete or even furniture and carpentry products developed made to measure and then entered in the catalog of suppliers.
