Appreciation towards LAN architecture for providing the following description:

A strategic project providing a social and environmental positive impact on the region. The building fully integrates into the landscape as well as it meets environmental quality standards, a fundamental aspect for the EDF’s building strategy.

This building, symbol of the long term and visible presence of EDF in the Meuse and Haute Marne region, hosts the company’s industrial records.Within the framework of the Meuse and Haute Marne economic support programme, EDF has decided to centralise all its intermediary Engineering Production Management archives in Bure-Saudron.

Until now, these paper copy archives had been stored in nuclear, hydraulic and thermal production units, as well as in engineering units and associated services.The new centre allows the documents’ organisation and it also ameliorates the storage and the utilisation processes. These archives, on paper-based and microfilm-based formats, will occupy about 70 km of shelves.

The building has also a laboratory for micro-films, specifically designed for this purpose.

The concept

We realised a five level, 19 m high building within a plot of 3.30 hectares comprehensive of an archives area covering approximately 1,400 m² and a total surface of approximately 7,000 m².

This approach results in:

– considerable saving in terms of the building’s envelope
– improved functionality translated by a reduced number of kilometres covered per year,
– a marginal impact on the landscape (with view points at a considerable distance from the building),
– the possibility of a maximum use of the excavated land around the building’s footprint to control water recuperation and treatment on the site,
– an energetically and environmentally extremely high performance building,
– the creation of a symbol representative of the approach taken by the Mouse and Haute Marne economic support programme.

The typology

An archives storage building needs to have a considerable inertia with a minimal exchange with its external setting. The need for fast and simple site management and optimum storage
efficiency led us to develop a simple and rational layout.

The building is divided into 2 programmes: archives and offices.

The archives’ part is composed by 20 storehouses of 200 m² each; with regulated temperature and hygrometry. The blocks can resist fire for 2 hours and they are equipped with a sprinkling system.
The offices’ part is N/W oriented, embedded in a natural slope planted with trees and plants. The offices have an ideal view on the surrounding landscape.

The landscape

Tree-planted surfaces give some advantages: from an ecological point of view the trees protect the building against climatic issues.

From an aesthetical point of view – and within an idea of landscape integration – they complete the building by inserting a pattern recurring from the landscape: the “merlons”, narrow strips of land planted with hardwoods.

The project of the landscape foresees the framing of the views from the offices by planting vegetable masses. Some framings already exist from the highway in the project’s direction. A game of sequences is set in combination with the architectural plan in order to vary the visuals and to put an accent on the building’s continuity with its landscape.

Energy

Heat production is principally based on renewable energies and a heat pump. The choice made for the ventilation was to use a double flow ventilation system with heat recuperation. This limits energy consumption resulting from heating and ensures the good sanitary quality of the air.

Low voltage luminaries will result in considerable savings in terms of internal loads. Storage areas will be equipped with presence detectors.

The high performance of the envelope combined with economic ventilation and lighting systems reduces energy requirements.

The use of renewable energies and a heat pump will result in a high level of energy autonomy. The total power consumed by the building represents 29 kWh/m².

The building’s envelope

To give the impression of a lightweight building in movement, we proposed incorporating stainless steel studs into the earth-coloured concrete cladding. This solution had the effect of blurring the building’s limits and reflecting the surrounding colours and changing seasons.

The envelope has a very high performance resulting from the materials employed and the technology used for attaching the concrete facing (reduced thermal bridges).

The combination of two layers of concrete (structure + facing) and insulation (30 cm) ensures that the building has a high level of inertia favouring comfort during the summer and reduces cooling requirements.

The facade

The elevations will incorporate a total of 120,000 stainless steel studs.

Stainless steel studs (7 cm diameter and 1 mm thick) will be incorporated into the formwork during the casting of the integrally coloured prefabricated concrete elevation panels.

The panels will be 15.65 m high and either 2.26 m or 2.33 m wide depending on whether they are on the long or short side of the building.

The 8 cm thick panels will be reinforced with concrete ribbing (+ 7 cm). The complex will be suspended from reinforced concrete walls and held in position using distancing jacks. The elevations will have a total thickness of 68 cm.

The facade’s building process was the subject of a patent.

为了对环境和社会产生积极影响，这个建筑的基本策略就是积极融入环境。

EDF公司是当地的一个象征，这个档案馆内存放着该公司的工业记录生产案例档案。与此同时，这些文件的拷贝件将分布在相应的核电，水电，热生产机构，单位和服务单元中。档案以纸张和微缩胶片为基础的储藏格式，在货架上全部展开排列可以达到70公里的长度。

建筑师为这栋高19米，一共5层，总面积达到7000平米的建筑设计了一个专门的微胶实验室。这个实验室具有可以节省大量建设资源；改进的存储的效率，减少占地空间；将对场地的挖掘减小到最少；成为一个积极环保的建筑等等优点。

建筑师认为档案储存建筑对环境的影响应降至最低，同时可以进行快速简单的管理以及优化其储藏效率，以此为依据开发了一个简单合理的布局。

建筑主要由档案处和办公组成。

档案馆由20个200平米的存储单元组成，每个都有单独的温度湿度测量调节，并配置喷灌系统达到两小时以上防火级别。
办公室面向西边和南边，能看见种植树木和其它植物的自然斜坡。

景观
从生态学和气候学考虑，主要种植灌木地被，还有蔬菜。因为临近高速公路，所以设置了一个序列性的景观，并将其与建筑结合。

能源
使用可再生能源以及热泵。通风选择了双向通风系统。这降低了能耗，并保证了空气质量良好。采用节能照明。存储区域配置探测器。通风系统，照明系统，结合高性能的幕墙系统共同作用，降低能耗。建筑能耗在每平米29 kWh。

建筑外表皮
建筑师采用了地球色，营造轻盈，模糊的效果，并能反映周围的色彩以及季节变化。表皮的热工性能非常高，可以减少冷桥。双层混凝土结构以及30厘米的绝缘层保证了夏季凉爽，从而减少了对冷气的依赖。

立面
立面上用到了12万颗镜面原色不锈钢螺栓，这些螺栓（7厘米直径，1毫米厚）完美的附着在一体浇筑的彩色混凝土钢筋预制板上，混凝土预制板尺寸为15.65M高，2.26M或2.23M宽（取决于是在建筑长边还是短边）。厚度为8厘米，骨架系统厚度为7厘米。整个幕墙系统厚度为68厘米。

立面建设过程属于专利技术。

The building’s life.
建筑的一天
