Quai Ouest大厦位于布洛涅—比扬古，它以150米长的外立面而引人注目。此次工程在维持整体框架结构不变的情况下对建筑进行重修，来应对多种挑战，并满足美观，节能和与环境相适应等要求。

The Quai Ouest building, located in Boulogne-Billancourt, possesses a broadly exposed 150-meter façade. The building has undergone a major restructuring and within this framework, the façades are designed to meet a particular challenge, both in terms of image and in terms of energy savings and the environment.

建筑的现状分析展现了一系列积极效果：与Canal plus，TF1以及国家广播频道相邻的优越地理位置，150米长的立面可视性良好，南面和西面的绝佳视野，令人满意的灵活结构，这一切都预示着此次改造的成功。与此同时，项目不得不对一些现存的不利条件进行修复，比如：街道的噪音，高层的阳光直射，过时的建筑外貌削弱了建筑的存在感，建筑入口不明显。

A rapid analysis revealed a number positive features: a lovely location in the so-called media triangle, facing Canal plus and TF1, both national broadcasting channels, good visibility along the 150 meters of the façade, perfect exposure to the south and the west, a flexible structure in good condition, a good omen for a successful upgrade. However, the project had to correct a certain number of negative aspects: exposure to noise of street traffic, absence of sun breaks on the highly exposed façades, outmoded architectural image which weakens the presence of the edifice, ambiguous and residual anchoring in the ground penalizing the ground floor.

基于对外墙结构的分析调查结果，建筑内部重新组织和规划了功能区域，并设计了新的立面通风双层玻璃系统来控制外部的直射光照。临河的景象让建筑展现一种变化和闪烁的立面。为了创造独特的反射，建筑立面玻璃面板以对角线折叠成两个三角形平面，一面映射天空，另一面则映射无限移动的城市风景。这种棱柱形的外立面覆盖物具有对外界的可感知性，并在尺度，聚集形态上展现戏剧化的效果；通过材料质量的把控和对装配技术的专业考究，建筑的外立面将作为其全新的特征，赋予建筑第二次生命。

After a structural diagnosis and surveys on the manufacturing method used on the façades, a new functional and spatial organization was planned, with a new façade system based on a ventilated double skin of glass on the interior upon which the sun- breaks would be affixed. The proximity of the river oriented the project toward a changing and shimmering façade. To produce this effect, the glass panels were folded diagonally, thereby creating two triangles separated by a raised edge, the first reflecting the sky and the second reflecting the endless movements in the cityscape. This prismatic covering with moving and crystalline reflections plays on the perception, scale, accumulation and transparence; through the quality of its materials and the preciousness of its implementation, a powerful new identity will now accompany this second life of the edifice.

考虑到种种因素，项目立面修正了现存的种种问题，同时利用一切场地优势。建筑统一了内部空间，加强了内部大厅的透明度和能见度，重塑了内部空间感受。该建筑始建于1990年，已不能满足国际化贸易需求。客户希望建筑通过内部功能重组来弥补它的退化，并以此适应新的环境要求，创造全新的建筑形象。

These observations taken into account, the project for the façade corrects these issues while also taking advantage of the all of the site’s potential. It unifies the volumes, enhances transparence and visibility of the lobby and changes the perception of the scale by grouping three frames, or 4.05 m. The building, dating from the early 1990s no longer met international commercial standards. The client had envisaged a heavy restructuring of the general functioning of the building to remedy its obsolescence, to adapt it to new environmental standards and to give it a new architectural identity.

建筑体块环绕花园作为中心，这一侧的立面由铝条代替白色帆布作为百叶窗。这种方式从技术角度来说，较之前项目概念有更好的表现力，同时这种材料也能在抵抗风和冲击力方面展现更好的效果。

On the garden side, in the heart of the block, wood has replaced aluminum, with blinds in colored canvas being replaced by aluminum strip blinds. From a technical point of view, the solutions proposed have provided better performance than the initial project concept, as the materials used being more resistant to shocks and the wind.
