项目概述：
瑞士媒体公司Tamedia的总部项目位于苏黎世市中心，占地1000平方米，位于一个更大的城市街区中，该街区目前是该集团主要建筑的所在地。场地位于街区的东部，具有沿Sihl运河延伸近50米的线性立面的特点。
新建筑的布局基本上回应了待拆除现有建筑的足迹，但这次与相邻建筑的立面保持了连续性，并充分利用了允许的最大高度，以优化建筑区块这一侧的可利用办公面积。
建筑的主入口位于Werdstrasse和Stauffacherquai街道的北角，实际上将成为整个建筑群的主要入口。建筑地上有7层，地下有2层，总净面积为8602平方米，此外还可以增加1518平方米，这对应于位于Stauffacherquai街8号相邻建筑屋顶上的两层扩建项目。
建筑特点：
从建筑角度来看，该项目的主要特点之一是提出了一个完全由木材设计的主要结构系统。除了从技术和环境角度来看的创新性外，这种结构系统还赋予了建筑内部空间和周围城市独特的视觉效果。为了强化和表达这一理念，建筑表皮完全采用玻璃，并特别注重实现低能量传输水平，以符合瑞士最新的严格能源消耗法规。
面向城市的一面，建筑还设有一个贯穿东立面整个高度的“中间”空间，除了在整体能源消耗策略中作为“热屏障”的作用外，它还成为一个独特的空间体验，设有休息区和连接不同办公层的垂直链接。这些“阳台”可以用作非正式的会议和休息区，其立面的特点是由可伸缩的玻璃窗系统组成，可以将这些空间转变为露天露台，从而加强建筑内部与周围景观之间的特殊关系。
创新性：
木材主要结构系统在很大程度上是该项目最重要的创新。从技术和环境角度来看，这种木材结构是对此类办公楼的独特回应，而且结构元素完全可见，也为工作氛围赋予了非常特殊的特征和高品质的空间感。
可持续性：
除了选择木材作为主要结构材料对可持续性的明显贡献 “木材是可再生的建筑材料，并且在施工过程中产生的二氧化碳最少” 外，整体机械系统设计符合能源问题的最高标准 “中间空间除了其“热屏障”功能外，还是公共空间的一部分，将使用办公区域的排气进行加热和冷却”。

The project for the headquarters of the Swiss media company Tamedia is situated in the heart of the city of Zurich in a 1,000m2 site within a larger urban block where the main buildings of the group are currently located. The site is positioned towards the east part of the block and has the particularity of developing through almost 50m of linear façade facing the Sihl water canal.
The implantation of the new building basically responds to the footprint of the existing building to be demolished but this time creating continuity with the facades of the buildings beside as well as taking advantage of the maximum allowed height in order to optimize the exploitable office area in this side of the building block.
The main access of the building is situated in the north angle of streets Werdstrasse and Stauffacherquai and will actually become the principal entry of the whole building complex. The building develops within 7 stories over ground floor with two basement levels for a global net area of 8,602m2 to which we can add 1,518 additional square meters that correspond to the two-floor extension project located on the roof of the neighbor building at number 8 of Stauffacherquai street.
From an architectural point of view one of the main features of the project is indeed the proposition of a main structural system entirely made designed on timber that, other its innovative character from a technical and environmental standpoint, gives the building a unique appearance from the inside space as well as from the city around. In order to reinforce and express this idea the building skin is entirely glazed and special attention was given to achieve a low energy transmission levels that responds to the latest and very strict Swiss regulations in terms of energy consumption.
Facing the city, the building also features an “intermediate” space throughout the whole height of the east façade that other its role as “thermal screen” within the general energy consumption strategy, also becomes a unique spatial experience with lounge areas and connection vertical links between the different office stories. These “balconies” can be used as informal meeting and rest areas that will also have the particularity of having a façade composed of a glass retractable window system that allow to “transform” these spaces into open air terraces that reinforce the privileged relationship between the interior building and its surrounding landscape.
Innovation:
The timber main structural system is in great extent the most significant innovation of the project. From a technical and environmental point of view the proposed this timber structure is a unique response to this type of office building and the fact that the structural elements are entirely visible also gives a very special character and high quality spatiality to the working atmosphere.
Sustainability:
Besides the clear contribution to sustainability on the choice of timber as the main structural material (only renewable construction material and the lowest C02 producer in construction process) the global mechanical system has been designed to meet the highest standards in energy issues(The intermediate space other its “thermal barrier” function is part of the public spaces that will be heated and cooled with the extraction air from the office area)
