我们的建议提出了一项重点关注三个主要问题的战略：如何以最可持续的方式在人口稠密的城市地点的一个几乎不存在的小场地上扩大现有建筑；如何将现有建筑与其周围环境重新连接，并创造新的、有吸引力的入口；如何建立一个以最佳方式利用当地和现有能源的低阈值主动能源系统，通过正确回答这些问题，为C2C优化策略创造了前提条件，提高了办公空间的灵活性。

Our proposal provides a strategy that focuses on 3 main issues: How to expand existing building in most sustainable way on a small almost non existing site in a dense urban location; How to reconnect existing building to its surroundings and create new and attractive entrance; How to create a low threshold + active energy system that utilise the local and existing energy resources in the best possible way. By giving the right answers to these issues we create preconditions for optimized C2C strategy and enhance the flexibility of the office space in the building.

为了平衡成本和经济稳健性，我们建议扩建BG14北侧的建筑。这是唯一合理和可能的地方，以扩大现有的BG 14大楼。从现有的2000个工作场所中，我们已经创造了可能，总共大约。5000个工作空间和21.000平方米额外空间。我们的建议是建造世界上最高的木制建筑结构。这在环境方面有一些明显的好处，但同时也增强了BG 14的标志性品质，并创造了新的、全球性的营销可能性。除了现有建筑之外，木质建筑还增强了它的功能，使它变得聪明、美观，是一座符合北欧设计传统的建筑。我们的建设性研究认为，在现有技术范围内，这是可能的。

In order to balance costs with economic robustness we propose to expand the building on the north side of the BG14. This is the only rational and possible place to expand existing BG14 building. From existing 2000 working places we have created possibility for in total approx. 5000 working spaces and 21.000m2 additional spaces. Our proposal is to build highest wooden building structure in the world. This has some obvious environmental benefits but also strengthens iconic quality of the BG14 and creates new and global marketing possibilities. Wooden addition to existing building enhance It’s functionality, makes it smart and aesthetically appealing, a building in the best of the Nordic design tradition. We constructive studies believe this to be possible within existing technology.

从步行的角度来看，奥斯陆市中心入口广场附近的城市环境可以说是最不适宜居住的地方之一。入口广场两旁都是障碍物。围栏，电车线路，一条高速公路和一个巨大的环形酒吧行人通道。隔壁邻居的街面是禁止的，将BG 14入口与拥挤的中央车站广场有效地隔离开来。行人在很大程度上被迫使用行人天桥或地下通道。我们的项目提出了一个新的诱人的入口区，将BG 14大楼与邻近的建筑重新连接起来，提供新的、有吸引力的购物中心地址和公共空间。

Immediate urban surrounding of the entrance plaza is arguably one of Central Oslo’s most inhospitable seen from a pedestrian point of view. The entrance plaza is flanked by barriers. Fences, tramlines, a motorway and a huge roundabout bar pedestrian access. The street-fronts of the next-door neighbors are forbidding, isolating the BG14 entrance effectively from the teeming Central Station Plazas. Pedestrians are largely forced to use footbridges or underpasses. Our project proposes a NEW and inviting entrance area, that reconnects BG14 building to the neighbouring buildings and provide NEW and attractive mall address and public space.

后座不是传统的建筑。没有地面地区可供能源生产，建筑物也没有大的屋顶面积。有可能设计出能源生产的房子吗？如何获取和利用建筑自身产生的能量，以及建筑与元素之间的相互作用？最大的挑战永远不是生产足够的能源，而是设法储存能源，以便以后使用。我们的项目提出了以“低门槛”技术解决方案来实现这一目标的解决方案。通过利用当地资源和适应当地的气候条件，我们创造了实现雄心勃勃的环境和能源目标的可能性。

Posthuset is not a conventional building. No ground areas are available for energy production; neither does the building have a large roof area. Is it possible to design house that is producer of energy? How to harvest and reuse energy that is generated by the use of the building its self and in the interaction between building and the elements? Biggest challenge is always not to produce enough energy but to manage to store it so that it can be used later. Our project proposes solution that makes this possible with “low threshold” technological solutions. By utilizing local resources and adapting to a local climatic condition we create possibility to achieve ambitious environmental and energy goals.

提议的主动屋概念收集能源。它通过适应当地条件和机遇的储存技术，在最佳时间以建筑内的过剩热量和环境能量为基础，在最需要时提供就地可再生能源。这一概念的基础技术是一个基于独特的动态热能储存技术和优化控制系统的节能和可再生能源系统。

The proposed Active House Concept harvests energy. It feeds on excess heat trapped in the building as well as ambient energy at optimal times by means of storage techniques adapted to local conditions and opportunities. This is done to supply in situ renewable energy when most needed. The technology underpinning the concept is an energy-efficient and renewable energy system based on a unique dynamic thermal energy storage technology and an optimized control system.

真正的挑战在于提出从根本上改善环境绩效的解决方案，同时平衡成本和市场意愿。我们提出了基于交叉层合木材技术的新立面解决方案，这将帮助业主在其生命周期内实现零排放。这种材料的选择不仅在建筑的新部分，而且在向南、向东和向西的现有立面上，将改善能源碳排放的减少。材料和交通。我们的建议增强并优化了建筑物的日光通道。在现有的一些原则的基础上进一步发展，我们提出的解决方案允许根据建筑物的方向改变玻璃表面的面积。木墙元件中提出的玻璃面积的总量平均约为正面表面的25%。

The real challenge lies in proposing solutions that radically improve environmental performance while balancing costs with market willingness. We propose new facade solution based on cross laminated timber technology that will help owners to achieve zero emissions over its lifecycle. This choice of material not only on new part of the building but also on the existing facades towards south, east and west will improve reduction in carbon emissions for energy, materials and transportation. Our proposal enhances but also optimises the access of daylight in to the building. Developing further on some of the existing principles we propose solution that allows for variation on the glass surface area depending on orientation of the building. Total amount of glass area proposed in the wooden wall elements is on average around 25% of the facade surface. 

BG 14有大量相同的楼层。随着建筑的扩建，我们从面积效率的角度优化了楼面平面图。我们创造了灵活的办公空间，既可以很容易地划分给不同的租户，也可以由一个较大的租户使用。如果以楼层作为主要的单元办公室规划，则每个工作场所的办公面积约为40平方米，景观办公室规划的面积约为11平方米，而将两者结合起来，则每个工作空间可达到15平方米。

BG14 has a large number of identical floors. With the proposed expansion of the building we optimize the floor plans in terms of area efficiency. We create flexible office space that can either be easily divided between various tenants or utilized by one larger tenant. If floors are used as mainly cell office plans we achieve approx 40 m2 per working place, 11 m2 for landscape office plans and for combination of these two we achieve 15 m2 per working space.
