Powerhouse Telemark
下载所需积分: 2
能源部门和建筑行业共同占全球工业温室气体排放的40%以上。随着全球人口的增长和气候危机的加剧，导致如COVID-19大流行等全球性干扰，建筑师面临着跨行业合作以更负责任地进行建设的挑战。
位于维斯特福德和特莱马克县历史悠久的工业城市波尔斯格伦，这座新的11层建筑标志着该地区辉煌历史的象征延续，因为特莱马克是19世纪初最大水电站之一的所在地。Powerhouse Telemark表明该地区对绿色经济的日益投资，使该县在新建筑的脱碳方面处于领先地位。Powerhouse Telemark的东南朝向外立面和屋顶每年将产生256,000千瓦时的电力，约为普通挪威家庭年用电量的20倍，剩余的电力将出售回电网。
这座倾斜且略呈圆锥形的建筑在东侧外立面上有一个明显的45°倾斜缺口，赋予其在周围Herøya工业园区的工业环境中独特的可识别性。建筑内部设有接待区、办公空间，包括两层共享办公空间、员工餐厅、顶层会议室和俯瞰峡湾的屋顶露台。两条大型楼梯连接建筑的底层和顶层，从接待区一直通往员工餐厅和顶层会议室。第九层有一条独特的直木楼梯，视觉上将员工餐厅和顶层会议室区域连接在一起，引导访客前往建筑的屋顶露台。
Powerhouse获得BREEAM优秀**认证，作为其大胆可持续发展目标的证明，不仅在当地社区中树立了可持续设计的灯塔，也为世界如何在未来广泛接受可持续建筑和设计提供了示范。
一个能量生产的外立面和屋顶。建筑引人注目的24°倾斜屋顶轻柔地向外延伸，超越建筑体量的极限，扩大屋顶表面，确保最大限度地收集来自光伏顶篷和建筑南侧外立面的太阳能。
在西侧、西北侧和东北侧，建筑外立面采用木制栏杆，提供自然遮阳，保护最受阳光照射的外立面。在木制栏杆后，建筑覆盖有Steni外立面板，赋予建筑统一的外观。建筑像被动房一样，超绝缘，整个建筑配备三层隔热窗。混凝土楼板赋予建筑类似石结构的密度，白天储存热量，晚上缓慢释放热量。每层边缘区域的低温系统与350米深的地热井相连，确保建筑高效制冷和供暖。
灵活且环保的室内解决方案。建筑的室内设计基于标准化原则，以减少新租户入驻时的不必要浪费。地板、玻璃墙、办公隔断、小厨房、照明和卫生间在所有楼层上采用相同的设计、颜色和材料。实际上，建筑的室内解决方案的灵活性，加上两层共享办公空间，使客户和未来租户能够轻松重新规划建筑，扩展或缩减业务，而无需搬迁。这意味着办公空间可以从桌面空间转变为资源空间，即使在远程工作场景改变传统办公布局需求时，也能最大限度地利用空间。
Powerhouse Telemark的材料调色板选择了环保可持续的特性。整个建筑采用坚固的材料，具有耐用性和低嵌入能量。这意味着使用当地木材、石膏和环保混凝土等材料，这些材料保持裸露和未处理。从厨房到地毯瓷砖和松散家具，均采用耐用且高质量的材料。地毯瓷砖由70%的回收渔网制成，木地板则由木材残余的工业用白蜡木拼花制成。此外，特别设计的可变标识系统允许在不产生不必要浪费的情况下，灵活调整不同办公空间的视觉表达。
为了将人工照明的需求降至最低，建筑采用了保守但高效的照明系统。建筑的屋顶还设有垂直玻璃缝隙，允许自然光透入三层顶楼。此外，选择轻质表面的松散家具也为室内照明提供了微妙的补充。
与其雄心勃勃的姐妹项目Powerhouse Kjørbo、Powerhouse Montessori和Powerhouse Brattørkaia一样，Powerhouse Telemark也渴望成为环境、社会和经济可持续建筑的典范，同时挑战我们对后COVID-19时代办公室外观的认知。
The energy sector and building industry account for over 40% of the global industry’s heat-trapping emissions combined. As the world’s population and the severity of the climate crisis continue to grow, precipitating global disruptions such as the COVID-19 pandemic, architects are challenged to work across industries to build more responsibly.
Situated in the historic industrial city of Porsgrunn in the county of Vestfold and Telemark, the new 11 story building marks a symbolic continuation of the district’s proud history as Telemark is home to one of the early 19th Century’s largest hydropower plants. Powerhouse Telemark indicates the area’s growing investment in the green economy, positioning the county as a leader in decarbonizing new construction. The south-east facing façade and roof of Powerhouse Telemark will generate 256 000 kWh each year, approximately twenty times the annual energy use of an average Norwegian household, and surplus energy will be sold back to the energy grid.
The skewed and slightly conical building features a clearly defined 45° tilting notch on the east-facing façade, giving it a clearly identifiable expression that stands out in the industrial context of the surrounding Herøya industry park. Inside, the building features a reception, office space, including two stories of co-working spaces, a shared staff restaurant, penthouse meeting spaces, and a roof terrace overlooking the fjord. Two large staircases connect the building’s ground and top floors, from the reception area and all the way up to the staff restaurant and penthouse meeting rooms. A distinctive straight wooden staircase reveals itself on the ninth floor, visually tying the staff canteen and penthouse meeting room area together and leading visitors to the building’s roof terrace.
In obtaining the BREEAM Excellent** certification as proof of their bold sustainability ambitions, Powerhouses stand as beacons of sustainable design not only in their local communities but also function as models for how the world can embrace sustainable architecture and design at large in the future.
An Energy Producing Façade and Roof. The building's striking 24° tilted roof gently slopes to surpass the extremities of the building’s volume, expanding the roof’s surface and ensuring a maximum amount of solar energy can be harvested both from the photovoltaic canopy and the building’s PV-cell clad south-facing façade.
To the west, north-west, and north-east the building is clad with wooden balusters providing natural shading on the most sun-exposed façade. Behind the wooden balusters, the building is covered with Steni façade panels which give the building a unified expression. Functioning just as a passive house, the building is super-insulated and features triple isolated windows throughout. The concrete slabs lend the building a density akin to that of a stone structure storing thermal heat during the day and slowly emitting heat during the evening. A low ex system with water loops in the border zones of each floor, assures that the building is efficiently cooled and heated through geothermal wells dug 350 meters below ground.
A Flexible and Environmentally Conscious Interior Solution. The interior design of the building is built upon a principle of standardization to reduce unnecessary waste as new tenants move into the building. The flooring, glass walls, office dividers, kitchenettes, lighting, and bathrooms have been given the same design, color, and materiality across all floors. Indeed, the flexibility of the interior solution of the building, combined with the building’s two-story co-working space, allows for the client and future tenants to easily re-program the building and expand or downsize their businesses without needing to relocate. This means that the office space may transition from desk space to resource space, allowing for the maximal utility of the space even when remote work scenarios changes the traditional office layout demands.
The material palette of Powerhouse Telemark is chosen for its environmentally sustainable qualities. Throughout, the building features sturdy materials known for resilience and low-embodied energy. This means using materials such as local wood, gypsum and environmental concrete which is left exposed and untreated. Everything from the kitchens to the carpet tiles and loose furniture are made from durable and high-quality materials. The carpet tiles are composed of 70% recycled fishing nets and the wooden flooring is made from industrial parquet of ash from wooden debris. Moreover, a specially designed foliating signage system allows for a certain amount of flexibility in tailoring the visual expression of the different office spaces without creating unnecessary waste that may be generated when brand-specific signage is removed or produced.
To reduce the need for artificial lighting to an absolute minimum, the building has a conservative but efficient lighting system. The building’s roof also features vertical glass slots, allowing for daylight penetration on the three top floors. Moreover, the choice of loose furniture with light surfaces allows for a subtle complement of the interior lighting.
Just like its ambitious sister projects Powerhouse Kjørbo, Powerhouse Montessori, and Powerhouse Brattørkaia, Powerhouse Telemark aspires to be a model for environmentally, socially, and economically sustainable architecture, while also challenging our conception of what our offices might look like in the post-COVID-19 era.
