在开发新的总部时，国际徒步和探险旅游公司ASI Reisen希望新的空间能够反映公司的工作文化，以及为世界各地的旅行者提供可持续的徒步旅行体验的承诺。这座新的木质建筑位于奥地利因斯布鲁克南部的纳特斯，采用开放式办公理念，提供了多种解决方案，使办公空间长期保持低碳排放。设计理念的灵感来自于自然与人文的共生，由ASI Reisen的员工和Snøhetta的设计团队共同开发。
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.
被郁郁葱葱的植物所包围，四层楼的木质结构结合了木质框架结构和实木元素，优化了材料的使用，并允许最大限度的开放平面。除了开放的办公理念和可持续的建筑方法，该建筑还采用了优化的可持续能源概念，基于高科技和低技术解决方案的结合。
Wednesday, August 26, 2020 — 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.
郁郁葱葱的外墙
悬挂在金属框架上的攀援植物组成的 "绿色帷幕 "覆盖了黑色的木质外墙，确保建筑和谐地融入青翠的森林环境中。这个绿色幕布由17种不同的温暖气候和常绿植物组成，生长在大花盆中，还可以作为眩光屏障，并为宽大的玻璃表面遮挡。在西侧，员工可以用这个金属框架作为阳台。118株攀援植物一年四季都会改变外立面的外观，因此也能适应季节性的保温需求。这个绿色缓冲区创造的小气候减少了建筑降温所需的能源。
A Lush Façade
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.
外立面采用了日本传统的木材保存方法，即所谓的烧木。由于略微炭化，因此碳化后的外墙既防水又耐用，不需要再上漆，同时还能防虫。地下室和建筑核心由钢筋混凝土制成。木头也被用于木梁-横梁-外立面、窗户、地板和吸音板。
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.
屋顶的雨水被收集到一个地下蓄水池中，并为外墙和花园的植物提供自动灌溉系统。绿色外立面和由73种当地植物组成的1215种新植物一起，也为当地的生物多样性做出了贡献，确保建筑成为人类和非人类社区的好邻居。
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.
绿色室内解决方案
开放式办公室是为ASI Reisen的65名员工设计的，但如果需要的话，可以根据未来的需要灵活调整。廊道空间创造了一个宽阔、开放、灵活的办公空间，包括各种独立的工作空间以及公共区域。宽大的玻璃表面提供了周围山林的全景，一个大型楼梯和一个双层高度的门厅为来访者创造了一个温馨的空间。大厅被亲切地称为 "大本营"，以大面积的墙板为切入点，介绍公司的历史。
Green Interior Solutions
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.
建筑内部的明亮和温馨的气氛通过使用轻质木材作为主要材料的选择而得到强调。员工的舒适度是优先考虑的因素，通过包含公共空间，如会议壁龛和房间、休闲室、自助餐厅、淋浴和更衣室。丰富的植物架为不同的工作区域提供了一个视觉上令人愉悦的细分，并提供了存储空间以及阅读和写作的非正式工作空间。一座桥梁将新建筑与现有建筑连接起来，其中包括会议室和休闲室。
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.
优化的能源概念
为了达到最佳效果，使用热动力建筑模拟对能源概念进行了测试和调整。一个可逆的空气-水热泵系统（40千瓦）通过地板加热或冷却来加热和冷却建筑。测量室内温度、湿度、二氧化碳和风的传感器，利用热升压和风压条件控制自然通风，使新鲜空气在建筑内循环。然后，不断监测的室内气候调节通风挡板的开启范围和时间。屋顶上覆盖着光伏板，产生的电力部分覆盖了建筑的用电量。
An Optimized Energy Concept
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.
通过提供能够使办公空间长期低环境足迹的解决方案，这个几层楼的灵活开放的办公空间为用户构成了一个健康和愉快的工作环境。该建筑是为ASI Reisen的需求而量身定做的，并以一种直观和慷慨的方式反映了公司的价值观。
By offering solutions that will enable the long-term low environmental footprint of the office space, this flexible and open office space over several floors constitutes a healthy and enjoyable working environment for its users. The building is tailor-made for the needs of ASI Reisen and reflects the values of the company in an intuitive and generous way.
