这座新的气候和大气研究观测站由R architecture设计，位于巴黎-萨克雷校区中，附属于巴黎理工学院。来自法国的建筑事务所提出了圆形平面布局，既满足了功能需求，又与周边景观建立起了全方位的连接。

R architecture designed the new facility of the SIRTA, a climate & atmospheric research observatory located in the Paris-Saclay campus and affiliated to the Polytechnic Institute of Paris. The circular plan proposed by the French architecture office solves an equation of use while establishing a 360° relationship with the landscape.

该大气研究观测站是一座法国国家研究设施，致力于气候和环境的研究。它是欧洲少数可以提供研究大气对流层表面到顶部的物化过程所需的器材、实验室和接待区的场所之一，人们可以通过这些研究预测热波和污染峰值，为可再生能源发电寻求创新的解决方案。

This atmospheric research observatory is a French national experimental facility dedicated to climate and environmental research. It is one of the few sites in Europe offering the instrumentation, laboratories, and reception capacities necessary to study atmospheric physico-chemical processes, from the surface to the top of the troposphere to better understand, anticipate and predict heat waves and pollution peaks as well as to find innovative solutions for renewable electricity production.

基地面朝巴黎综合理工学院，位于连接校园湖泊北岸和保护树林的草坪中间。R architecture在这里设计了一座向四周伸展的圆形建筑。精心选择的基础形状和审美特征赋予了建筑巨大的自主性，可以更好地完成其所肩负的任务，包括监控、实验和教学。主体建筑呈螺旋形上升，中部的“可视空间”被研究实验室围合，顶层是一片配有器材的平台。

Facing the École Polytechnique, in the centre of a meadow stretching between the north shore of the campus lake and a preserved wood, R designed a round building that radiates towards its environment, both terrestrial and spatial. The chosen elementary form and careful aesthetics give the whole a great deal of autonomy to better ensure all it’s missions: surveillance, experimentation and education. The main building accommodates in an ascending spiral, a central “visibility space” encircled by research laboratories crowned by an instrumented platform.

建筑中部是一个多功能空间，可以用来举办工作坊、会议和公共活动。拱顶的圆洞让自然光洒满空间，将SIRTA中的活动与天空联系到了一起。围绕空间的是一条宽敞的走廊，连接所有侧边的调查实验室。工作空间四面由玻璃围合，为使用者提供了看向建筑核心区和周围自然景观的开阔视野。

The central space is a versatile place capable of hosting workshops, conferences and public events. Bathed in natural light thanks to a dome pierced at the zenith, it stages the activities of SIRTA and its relationship to the sky. Around this space, a large gallery serves all the research laboratories which are located in a third ring. Glazed on both sides, the workspaces offer tangent views towards the heart of the building and the surrounding nature.

室内走廊的尽头是一座通向屋顶的楼梯，那里安装了各种各样的测量设备。平台边缘由22根柱子支撑，中部为一米高的技术空间。凸起的圆柱体如同长焦镜头一般，外部覆盖抛光铝板，反射周边的环境和天空。

The interior gallery is extended by a staircase serving the roof equipped with various measuring instruments. This platform is supported by 22 poles located on the edge. At its centre, a technical space emerges by one meter. Like a telephoto lens, this protruding cylinder is coated with polished aluminium that reflects the environment and the sky.

建筑采用混凝土结构，立面交错覆盖阳极氧化铝板和通高玻璃板。混凝土一次浇筑成型。混凝土柱、凸出的铝肋和屋顶的钢制护栏共同形成了建筑的韵律。带有屋顶的外廊亦可以保护立面免受日晒雨淋。

A concrete structure and an alternation of solid anodized aluminium panels and full height glazed panels make the building. The concrete is poured in one go. The rhythm is set by the concrete pillars, the aluminium thorns and the steel guardrail of the roof. The exterior gallery which houses a covered circulation also protects the facade from rain and sun.

外屋和停车空间为长方形，与圆形的观测栋相平衡，将设施与后勤道路楔接在了一起。

Rectangular in shape, the outbuilding and parking spaces counterbalance the roundness of the observatory building and wedges the facility to the service road.
