架构师提供的文本描述。新的诺恩市政厅配备了被动和主动节能系统。这两个系统的发展都是从设计的早期阶段开始的，因此建筑物的最终结果显然取决于它们的存在。该项目受到能源评级的影响，节省了60%的能源。

Text description provided by the architects. The new Noain City Hall is equipped with passive and active systems of energy saving. The development of both systems was included from the early stages of design, so that the final outcome of the building is clearly determined by their presence. The project has been subject to an energy rating, resulting in a 60% saving.

照明通常涉及到办公大楼较高的能耗。为了尽量减少其影响，建造该建筑物的目的是在其所有地区获得最高水平的阳光。

Lighting usually involves the higher energy consumption in an office building. To minimize its impact, the building was constructed with the aim to obtain the highest level of sunlight in all its areas.

该项目被认为是一个层的增加。这座建筑的中心是一个空旷的空间，上面有一个天窗，把北光引入所有的流通空间。沿着这个空隙，主楼梯连接着不同的层次。在它周围，一条走廊提供通往办公室和会议室的通道。这些区域被分隔开来，没有到达天花板，所以中央阳光也通过私人空间进入。

The project is conceived as an addition of layers. The center of the building is an empty space, covered by a skylight that introduces northern light to all the circulation spaces. Along this void the main staircase connects the different levels. Around it, a corridor provides access to the offices and meeting rooms. These areas are separated by divisions that do not reach the ceiling, so that the central sunlight enters through the private spaces, as well.

正面由半透明的双层皮肤组成。玻璃向内和聚碳酸酯向外，分离25厘米。因此，阳光穿透了整个建筑的外壳。外层是一个“有机”网格的扁钢，位于2至3米之间的双半透明皮肤。水平杆作为“晴雨表-太阳”，减少了夏季阳光的影响。

The facades are composed of a translucent double skin. Glass inwards and polycarbonate outwards, separated 25cm. The sunlight, therefore, enters through the whole building envelope. The outer layer is an 'organic' grid of flat steel bars, located between 2 and 3 meters away from the double translucent skin. Horizontal bars serve as ‘brise-soleil’, reducing the impact of summer sun.

在这个网格上，爬虫生长，最终，将完全覆盖整个建筑。爬虫是落叶的，它们充当季节性过滤器，在夏季吸收太阳辐射，并允许它在冬季加热双层皮肤之间的空气室。夜间，植被减少辐射损失，防止内部温度下降。此外，“绿色增长网格”提供了额外的好处，滋润环境，软化温度和吸收二氧化碳。

Over this grid, creepers grow and, eventually, will cover completely the building. The creepers are deciduous, and they work as a seasonal filter, absorbing solar radiation in summer and allowing it to heat the air chamber between the double skin in winter. During the night, the vegetation reduces radiation losses and prevents from inner temperature drop. Furthermore, the ‘green growing grid’ provides added benefits moistening the environment, softening the temperatures and absorbing CO2.

主动系统

Active Systems

主要的能源是地热。建筑物通过热泵和一套100米深的探头与地面进行能量交换。地热能是一种高性能的系统。它利用地面的稳定性和低的热振荡，通过一个垂直管道网络与之交换热量，那里有水流动。这种交换，允许季节间的能量积累，在夏天给地面提供热量，在冬天提取热量。

The main source of energy is geothermal. The building exchanges energy with the ground through heat pumps and a set of probes 100m depth. Geothermal energy is a high performance system. It takes advantage of stability and low thermal oscillation of the ground to exchange heat with it through a network of vertical pipes where water flows. This exchange, allows inter-seasonal energy accumulation, giving heat to the ground in summer and extracting it in winter.

建筑内部的冷热分布是通过辐射地板进行的。它由嵌入在地板上的微管组成的网络，在一个大型的加热和冷却系统中将所有的表面旋转。该系统工作在低温度的变速器，避免吃水，确保高标准的舒适性。安装在建筑物顶部的小型燃气锅炉，在需要立即达到所需温度的时候，可以改善系统的性能。

The distribution of cold and heat inside the building is done through a radiant floor. It consists of a network of micro tubes embedded in the floor, turning all the surface in a large heating and cooling system. This system works with lows temperatures of transmission and avoids draughts, ensuring high standards of comfort. A small gas boiler placed on the top of the building improves system performance in those periods when it is necessary to reach required temperatures instantaneously.

此外，该建筑还配备了机械通风，满足了空气更新的需要，并改善了其湿热状况。顶部的天窗作为太阳能烟囱工作，允许在夏季通过其机动格栅疏散热空气。另一方面，双层皮气室在每扇窗户旁都有手动格栅，其操作允许积聚或散热热量。

Moreover, the building is equipped with mechanical ventilation, that satisfies the needs of air renewal and modifies its hygrothermic conditions. The top skylight works as a solar chimney, allowing the evacuation of hot air in summer through its motorized grilles. On the other hand, the double skin air chamber has manual grilles beside each window whose manipulation allows to accumulate or dissipate heat.

最后，所有系统、照明、供暖、冷却和通风都由中央计算机控制和调节。它允许充分优化能源效率，同时满足所需的舒适条件。应该指出的是，在诺恩市政厅，技术是通过其他感官感知不到的。器官的功能居住，成为公里的管道，无论是地热开采，微型毛细血管分配，电信光纤，或照明电力。

Finally, all systems, lighting, heating, cooling and ventilation are controlled and regulated by a central computer. It allows fully optimize energy efficiency while meets the required comfort conditions. It should be noted that, in the Noain City Hall, technology is not seen but is perceived through other senses. The organs where functions reside, become kilometres of pipes, whether geothermal extraction, micro-capillaries distribution, telecommunications fiber optic, or lighting electricity.

用户无法看到不同的系统，任何访问者都不会注意到这些系统。也许他能感觉到安装在吊顶上的照明、温度或运动感应器，这有助于使能源消耗合理化。所有的系统仍然存在，但不再是空间的主要特征。有机隐喻作为一个具有明确功能的有形器官的身体，被另一个身体所取代，其中身体只是皮肤，是外部和条件内部之间的边界。这些器官没有被发现，或者被重组成能源管理和信息的模糊系统。简而言之，技术越先进，它就越看不见。

The user can not see the different systems, which go unnoticed by any visitor. Perhaps he can sense the lighting, temperature or movement sensors embedded in the suspended ceiling, which serve to rationalize energy consumption. All systems are still there, but no longer are the main character of space. The organic metaphor as a body with visible organs with defined functions is replaced by another in which the body is only the skin, the boundary between exterior and a conditioned interior. The organs are not seen, or have been restructured into fuzzy systems of energy management and information. In short, the more advanced technology, the more invisible it is.
