奥地利绿色生态开放式办公楼

项目位于奥地利因斯布鲁克市（Innsbruck）以南的纳特斯镇（Natters），是一座新建的木制开放式办公楼，建筑秉承了环境友好的理念，完美融入周边环境。在项目初期，国际徒步与冒险旅行公司ASI Reisen，希望建造一个能够彰显公司文化的总部大楼，为全球旅行者提供可持续的徒步旅行体验。受到自然与人类共生的启发，ASI Reisen员工与Snøhetta的设计团队共同提出了该项目的设计构想。

When developing its new head office, international trekking and adventure travel company ASI Reisen sought to have its new space reflect the company’s working culture and commitment to offering sustainable trekking experiences for travelers around the world. Situated in Natters, just south of Innsbruck, Austria, this new timber building with an open office concept offers several solutions that will enable the long-term low environmental footprint of the office space. Inspired by a symbiosis between nature and humanity, the design concept was developed together with ASI Reisen’s employees and the design team from Snøhetta.

四层的办公楼掩映在郁郁葱葱的植被中，木结构与实木元素的结合，激发了材料的潜力，并在最大程度上为设置开放式空间提供了条件。除了将开放式办公模式与可持续建筑结构结合外，项目中还运用了多种主动与被动式生态技术，进一步贯彻了能源可持续发展的理念。

Surrounded by a lush exterior, the four-story timber structure combines timber frame construction with solid wooden elements to optimize material use and allow for the greatest amount of open floor plans. In addition to the open office concept and sustainable construction methods, the building features an optimized and sustainable energy concept, based on a combination of high-tech and low-tech solutions.

为了能够在这个人类赖以生存的星球上继续生存发展，在建造建筑物时，对自然保护和能源效率的考虑，应与对舒适度的需求同样重要。“ASI的新总部建筑采用了环保型木结构，秉承了先进的可持续能源理念，同时为员工营造了一个愉快且现代的工作氛围。该项目可以被视作一个未来住宅与办公空间的模版。”Snøhetta董事Patrick Lüth解释道。

For humans to continue to live and thrive on this planet, the buildings we inhabit and spend most of our lives in need to be built with as much consideration for natural preservation and energy efficiency as for comfort. “With its resource-saving timber construction and sophisticated sustainable energy concept, the new ASI headquarters marks an inspiration for responsibly constructing our homes and office spaces for the future. At the same time, the new office space offers a pleasant and modern working atmosphere for its employees,” explains Patrick Lüth, Managing Director of Snøhetta’s studio in Innsbruck.

建筑立面采用了日本传统的木材保存方法，即“烧杉”（yakisugi）。木材碳化的表面既防水又耐用，不需要刷漆保护，同时还能防虫。竖框横梁的立面，窗户，地板以及隔音板同样为木制。地下室与建筑的核心筒则是由配有钢筋的混凝土浇筑而成。

For the facade, a traditional Japanese method of wood preservation was used, known as yakisugi. Slightly charred and thus carbonized, the façade is both waterproof and durable without the need for further painting, while also protecting against insects. The basement and the building core are made of reinforced concrete. Wood was also used for the mullion-transom-façade, the windows, floors and acoustic panels.

藤蔓植物攀附在金属框架上，宛如郁郁葱葱的“绿色窗帘”，遮盖了黑色的木质立面，使建筑和谐地融入了周边的森林环境中。立面上的植被生长在金属框架与木质立面缝隙空间里的花盆中，共有17种不同的温带常绿品种。“绿色窗帘”遮蔽了大面积的玻璃幕墙，从而起到了减弱眩光的效果。118株藤蔓植物，随着季节的变化改变着建筑的外观，同时起到了隔热的作用，在四季都为室内营造了舒适的体感环境。绿色缓冲区形成微气候，节约了室内降温所需的能源。在西侧，金属框架还作为阳台供员工使用。

A “green curtain” of climbing plants growing on a suspended metal frame covers the blackened wooden façade, ensuring the building blends harmoniously into its verdant forest surroundings. Composed of 17 different warm weather and evergreen species growing in big planters, this green curtain also serves as a glare shield and for shading the generous glass surfaces. On the western side, the employees can use this metal frame as balcony. The 118 climbing plants change the appearance of the façade throughout the year and thus also adapt to seasonal thermal insulation needs. The microclimate created by this green buffer zone reduces the energy required for cooling the building.

地下蓄水池收集了屋顶的雨水，并为立面花园的自动灌溉系统供水。开放式工作空间内共有73个当地种类的1215盆植株。这些植物与绿色立面一起为当地物种多样性做出了贡献，在建筑、人类与自然之间创造了一个和谐的共生环境。

Rainwater from the roof is collected in an underground cistern and feeds the automatic irrigation system for the plants on the façade and the garden. Together with the 1,215 new plants in the open space consisting of 73 local species, the green façade also contributes to local biodiversity, ensuring that the building is a good neighbor to its human and other-than-human communities.

Snøhetta事务所专门为ASI Reisen的65名员工设计了开放式工作区， 员工们可以根据未来的工作需要灵活使用该空间。宽敞，开放且灵活的办公空间，宛如一个画廊，包括了各种各样的独立工作区与公共空间。透过大面积的玻璃幕墙，人们可以尽赏周围群山与森林的全景。宽大的楼梯与二层通高的门厅为访客们营造了热情好客的空间体验。大堂内的巨型照片墙展示了公司的历史，成为入口空间的最大亮点，被员工们亲切地称为“大本营”。

The open-plan office is designed for ASI Reisen’s 65 employees but can be flexibly adapted to future needs if required. Gallery spaces create a large, open and flexible office space, including a variety of individual workplaces as well as communal areas. Generous glass surfaces offer panoramic views of the surrounding mountains and forests, and a large staircase and a double-height foyer create a welcoming space for visitors. Affectionately called Base Camp, the lobby is a point of entry where the history of the company is presented on large wall panels.

轻质木材作为主要室内用材，渲染出建筑内部明亮而温馨的氛围。对公共空间的精雕细琢，体现了建筑师对员工体验舒适度的优先考虑。这些公共空间包括，会议室、休息室、自助餐厅、淋浴和更衣室等。不同的工作区内布满花架，这些花架在为人们带来视觉愉悦的同时，可以作为储存空间以及休闲工作空间使用。会议室与休闲区设置在另一栋现有建筑中，并由一座桥连接到新建的办公楼。

The bright and welcoming atmosphere of the building interior is emphasized by the use of light timber as the main material choice. Employee comfort is prioritized through the inclusion of communal spaces such as meeting niches and rooms, a relaxation room, a cafeteria, showers and changing rooms. Shelves abundant with plants provide a visually pleasing subdivision of the different working zones and offer storage space as well as informal workspaces for reading and writing. A bridge connects the new building with an existing building which includes meeting and relaxation rooms.

为了达到最佳节能效果，Snøhetta事务所运用了热动态建筑模型来验证与调试项目的能源优化理念。地板下的空气水热泵系统(40kw)，通过空气与水的可逆性循环，达到为室内升温或降温的目的。自动传感器可以检测室内温度、湿度、二氧化碳和风速，并利用温度和风压条件来控制自然通风，为建筑内部带来新鲜空气。通风口打开的幅度与时长同样取决于对室内气候环境的监测。屋顶上还设置了太阳能光伏板，产生的电能抵消了部分的建筑能耗。

To achieve optimal results, the energy concept was tested and adapted using a thermal-dynamic building simulation. A reversible air-water heat pump system (40 kW) heats and cools the building via underfloor heating or cooling. Sensors measuring room temperature, humidity, CO2 and wind, control the natural ventilation using thermal lift and wind pressure conditions to circulate fresh air through the building. The constantly monitored room climate then regulates how wide and how long the ventilation flaps are open. The roof is covered with PV panels, and the electricity generated partly covers the power consumption of the building.
