架构师提供的文本描述。新的国防部大楼是一个复杂的行动，因为它的双重城市和建筑性质。它位于一个占地16.5公顷的土地上，分为三个地块：东部的Victor地块(8.5公顷)是Citéde l‘Air的家，其建筑物要么被拆毁，要么被修复；中央瓦林地块(8公顷)被该部的主楼占用，科内西部地块被移交给一个商业房地产项目。

Text description provided by the architects. The new Ministry of Defence building  is a complex operation due to its dual urban and architectural nature. It is located on a 16.5-hectare site divided into three plots: the Victor plot to the east (8.5 hectares) is home to the Cité de l’Air, whose buildings have been either demolished or rehabilitated; the central Valin plot (8 hectares) is occupied by the ministry’s main building, and the western Corne Ouest plot is given over to a commercial real estate programme.

Anma的任务是协调三块地块，建造该部的主楼(146，500平方米)，在Valin地块上重建Perret大楼，以及在Victor地块上建造两座建筑物。

ANMA was tasked with coordinating the three plots, building the ministry’s main building (146,500 m²) and restructuring the Perret building on the Valin plot, as well as constructing two buildings on the Victor plot.

一个宏伟而谨慎的建筑项目的目标是将原先分散在巴黎周围15个地点的铁道部建筑组合在一起。这座建筑既雄伟又谨慎，结合了标志性的景观和占场地面积60%的花园景观，这要归功于高跷建筑的选择，这为一系列种植庭院腾出了空间。该计划是基于一个动态形状，从一个六边形开始，然后在多个方向展开。出于安全原因，军事总部设在中央，远离位于外围建筑物的不太敏感的职能，而指挥和控制中心则设在地下混凝土掩体中。

A majestic and discreet building The project’s goal was to group together the ministry’s buildings previously scattered across some 15 sites around Paris. The building is both majestic and discreet, combining a visibly monumental character with a garden landscape representing 60% of the site area, thanks to the choice of building on stilts which frees up space for a series of planted courtyards. The plan is based on a dynamic shape that starts off with a hexagon and then spreads out in multiple directions. For security reasons, the military headquarters is positioned centrally, away from the less sensitive functions located in outlying buildings, while the command and control centre is housed in an underground concrete bunker.

外墙的混凝土结构隐藏在由丝网印刷玻璃和陶瓷玻璃组成的双层表面之下，这些玻璃以不同色调的白色，即和平的颜色，作为水平板条铺设。官方的主要入口是由一个高耸的裂缝形成的，上面有一个深灰色的钢外墙，从屋顶的褶皱处一直延伸到上面。在里面，露台的正面覆盖着绿色和蓝色的彩色玻璃板。这些面板被布置成像素化的表面，并被设计成军事伪装。

The concrete structure of the outer wall is concealed beneath a double-skinned façade of screen-printed glass and ceramic glass laid as horizontal slats in different tones of white, the colour of peace. The official main entrance is formed by a towering crevasse with a dark grey steel façade, continuing on from the folds of the roof. Inside, the patio façades are covered in coloured glass panels in shades of green and blue. The panels are laid out as pixelated surfaces and designed to suggest military camouflage.

从环形公路上可以看到这座建筑的屋顶，就像一张巨大而黑暗的折纸。这第五个外观展示了那种锯齿状的线条，唤起了隐形飞机的军事技术。它被三座45米高的通风烟囱所占据.

The building’s roof can be seen from the ring road, resembling a huge dark origami. This fifth façade displays the sort of jagged lines that evoke stealth aircraft military technology. It is dominated by the three towering 45-metre ventilation chimneys.

这座17000平方米的建筑被纳入该项目，由佩雷特兄弟于1934年建造，并已修复。它不规则的拐角处连接着铁道部伸出的手臂。采用与新建筑相同的方法，珀雷特建筑被金属覆盖屋顶，使它与整个项目的视觉一致性。

The 17,000-m2 building incorporated in the project was built by the Perret brothers in 1934 and has been rehabilitated. Its irregular corner connects to the ministry’s extended arms. Adopting the same approach as used for the new constructions, the Perret building is covered with a metal over-roof, giving it visual consistency with the overall project.

该项目设计为一台自然机器，能够利用现场生产的可再生能源，在80%的时间内自主运行。其128，000平方米的办公空间配有打开的窗户，没有空调。该场地的总能耗(通风、空调、热水和照明)为每年每平方米43千瓦时。6500平方米的光伏屋顶面板提供了高达80%的能源需求。四口地热井几乎满足了所有的冷却需要，要么直接交换辐射天花板，要么通过两个泵从数据中心回收热量，并能够满足大约70%的供暖需求，并提供浴室设施所需的100%热水。新鲜的空气，由植物和水冷却，利用在庭院和自然提取大烟囱得益于温度梯度和风。

A natural machine The project is designed to be a natural machine capable of using the renewable energy produced on-site to operate autonomously 80% of the time. Its 128,000 m2 of office space are equipped with opening windows and are not air conditioned.  The site’s total energy consumption (ventilation, air conditioning, hot water and lighting) is 43 kWh per m² per year. The 6,500 m² of photovoltaic roof panels provide up to 80% of the site’s energy needs. Four geothermal wells meet almost all cooling needs, either by direct exchange in radiant ceilings or via two pumps that recover calories from the data centre, and are capable of meeting around 70% of heating needs and providing 100% of hot water needed for the bathroom facilities. Fresh air, cooled by the plants and water, is harnessed in the courtyards and extracted naturally by the large chimneys thanks to the thermal gradient and wind.

 Enviromental Scheme

环境方案

在办公楼中，方案所需的传统分区办公室模式已适应当代的需要，如节能、工作场所舒适和保持人的规模。它还尊重军团精神，这是军队的核心价值，在综合的场地配置方法中被赋予具体的形式。

In the office building, the traditional model of partitioned offices required by the programme has been adapted to meet contemporary needs, such as energy saving, comfort in the workplace and retaining a human scale. It also respects the esprit de corps that is a core value of the army, and that is given concrete form in the composite approach to site configuration.
