Innoasis 办公大楼丨挪威丨Helen & Hard

Innoasiss是一栋有悠久历史的建筑，最近被改造成一个现代化的办公环境。在1978年，Sverdrupsgate 27号大楼是新成立的挪威石油管理局的总部大楼。该建筑拥有合理的平面图，以及由混凝土柱和 DT 肋梁构件组成的清晰可辨的工业建筑系统。现有的承重系统被保留下来，并在新的内部结构中得以体现。

Innoasis is an office building with a strong history transformed into a modern work environment. In 1978, Sverdrupsgate 27 was built as the headquarters of the newly established Norwegian Petroleum Directorate. The building had a rational plan and a clear and legible industrial building system made up of concrete columns and DT rib elements. This existing load-bearing system has been preserved and made visible in the new interior.

主要的改造变化是将旧后院改造成有顶的中庭，形成一个新的强有力的空间中心。植入木结构创造了新的流线长廊，非正式的会议空间，并在栏杆上种植了绿色植物。这一结构也支撑中庭上方的玻璃屋顶。它由胶合梁框架和天然云杉圆柱组成，云杉圆柱支撑着弧形切割的 CLT 楼板构件。

The main transformational change was to turn the old backyard into a covered atrium which forms a new strong spatial center. A wooden structure has been implanted here creating new galleries for circulation, informal meeting places and integrated green plants in the balustrades. This structure also holds the glass roof over the atrium. It consists of a framework of glulam beams and round, natural tree columns of spruce which hold the curved cut CLT floor elements.

尖屋顶和两根新立柱支撑起围绕中庭的阁楼空间，完善了方形布局。四根支撑屋顶的立柱使光线和空气流入三层的办公空间，提高了夹层的可能性和空间的多样性，强调并创造了令人兴奋的居住景观。不仅如此，屋顶为太阳能板、屋顶的灌木、长满鲜花的草地和当地原生植被提供多角度的表面，为场地增添了生态价值。

Two new volumes with pointed roofs complete the squared organisation of the lofts around the atrium. The four roof volumes allow light and air into the office spaces on the third floor, adding the possibility for mezzanines and a variety of spaces to enhance and create an exciting landscape to inhabit.  Additionally, the roofs provide angled surfaces for solar panels, rooftop sedum, flower meadows, and local plant species, adding to the ecological value of the site.

中庭形成空间的核心，为建筑建立了新的社交设施。会议室环绕着中庭层层分布，灵活的工作区域沿着外立面形成外层空间。

The atrium forms the core and establishes the new social infrastructure of the building. Meeting rooms are gathered around the atrium in layers and flexible workspaces form an outer layer along the facades.

整个工作区域，天花板和技术系统都是按照网格系统组织和准备的，便于将来重新安排，可以在单元式办公室和办公景观之间移动。

The whole work space, ceiling and technical systems are organized and prepared in a grid system for easy future rearrangements that can be shifted between cellular offices and office landscape.

室内的氛围品质通过和新的木质元素的结合，与现存的混凝土结构形成对比。铺设在混凝土肋梁之间的木质板和中庭的稻草墙纸也是吸音元素的一部分，有助于实现良好的隔音效果。作为中庭的核心特征，现存的旋转混凝土楼梯经过翻新。在整个改造过程中，立面的面板和家具元素被重新利用。绿植作为建筑的重要部分，在创造中庭的绿洲般的氛围中至关重要。

The atmospheric quality of the interior plays on the contrast between existing concrete structure in combination with new timber elements. Wooden slats laid between the concrete ribs and straw wallpaper in the atrium are also part of sound absorption elements contributing to a very good acoustic quality. An existing spiral concrete stair is renovated and placed as a central feature in the atrium and façade panels and furniture elements have been reused throughout the transformation. Green plants are an important part of the architecture and are essential in creating the oasis-like atmosphere of the atrium.

虽然在改造过程中，建筑的使用面积增加了1000平方米，相较于原建筑，用于供暖和降温的热能被降低了1/3。传输能源的需求也较原建筑降低了1/4。相较于类似的建筑，该项目的温室气体排放也降低了超过50%， 相当于 BREAAM-NOR 中温室气体减排标准中的满分。

Although the building is around 1000m2 larger with the transformation, the thermal energy use for heating and cooling is reduced to 1/3 compared to the original building. Requirements for delivered energy is reduced to 1/4 of the original building. The project has a greenhouse gas reduction of over 50% compared to a reference building, equivalent to a full score for greenhouse gas reduction in BREAAM-NOR.
