Brattørkaia发电站位于挪威特隆赫姆，在地球赤道以北63°，那里的阳光在不同季节有很大的差异。这为探索如何在具有挑战性的条件下收集和储存太阳能提供了一个独特的机会。这座18000平方米的办公大楼位于港口边，通过大楼后端的人行桥与特隆赫姆中央车站相连。滨水区的立面是该建筑最纤细的一面，使该项目在阅读时与邻居的规模相似。外墙采用黑色铝和太阳能电池板，反映在邻近的特隆赫姆峡湾中。平均而言，Powerhouse Brattørkaia每天生产的电力是其消耗量的两倍以上，并将通过当地的微电网为其自身、其邻近的建筑、电动巴士、汽车和船只提供可再生资源。

Powerhouse Brattørkaia is located in Trondheim, Norway, 63° north of the Earth’s equator, where sunlight varies greatly between the seasons. This presents a unique opportunity to explore how to harvest and store solar energy under challenging conditions. The 18 000 m^2 office building is situated by the harbor and connects to Trondheim Central Station via a pedestrian bridge on the rear end of the building. The waterfront façade is the slimmest face of the building, allowing the project to be read at a similar scale with its neighbors. Clad with black aluminum and solar panels, the façade is reflected in the adjacent Trondheim Fjord. On average, Powerhouse Brattørkaia produces more than twice as much electricity as it consumes daily, and will supply renewable energy to itself, its neighboring buildings, electric buses, cars and boats through a local microgrid.

该建筑非常节能，利用一系列技术从根本上减少其日常运作的能源使用。这是通过以下方式实现的：对建筑进行绝缘以达到最大效率；安装智能气流解决方案以减少对加热的需求；为通风和灰水（除厕所外的所有来源的废水）提供热回收解决方案；使用海水进行加热和冷却；只使用节能电器。日光条件在整个建筑设计中得到了优化，人工照明的使用保持在最低水平。

The building is extremely energy efficient, leveraging a series of technologies to radically reduce energy use for its daily operations. This is accomplished through insulating the building for maximum efficiency, installing intelligent solutions for airflow to reduce the need for heating, heat recovery solutions for ventilating air and greywater (wastewater from all sources except toilets), using seawater for heating and cooling and implementing only energy-efficient electrical appliances. Daylight conditions are optimized throughout the building design and artificial light use is kept at a minimum.

为了让人类继续在这个星球上生活和繁衍，在我们居住和度过大部分生命的建筑中，这些建筑的建造需要考虑到自然保护和能源效率，就像考虑到里面的人的舒适一样。作为世界上最北端的能源积极性建筑，Powerhouse Brattørkaia正在为未来负责任地建造我们的家园和办公场所树立一个榜样。

For humans to continue to live and thrive on this planet, and in the buildings we inhabit and spend most of our lives in, these need to be built with as much consideration for natural preservation and energy efficiency as for the comfort of the people inside them. As the world’s northernmost energy-positive building, Powerhouse Brattørkaia is setting an example for responsibly constructing our homes and office spaces for the future.

一个诱人的中庭之光。从港口正面看，建筑立面的两侧向内凹陷，让人联想到建筑是如何迸发能量的。从相反的方向看，建筑的倾斜屋顶在其平面的中央露出一个切口，使日光流入办公空间。在这个被照亮的核心内有一个中庭，其功能是一个公共花园，两侧有水平玻璃窗，为下面的食堂提供天窗。这个倾斜的采光井让日光进入建筑的每一层，让在里面工作的人看到城市的美景。中庭也限制了建筑内部所需的人工光线。大面积的玻璃窗和宜人的开放空间充斥着日光，有助于创造一个舒适和诱人的工作环境。

An Inviting Atrium of Light. Viewed from the harbor front, the building façade’s sides cants inwards, bringing associations to how the building is bursting with energy. From the opposite approach, the sloping roof of the building reveals a cutout in the center of its plan that allows daylight to flow into the office spaces. Within this illuminated core is an atrium that functions as a public garden with horizontal glass windows on the sides, providing skylight into the below canteen. This skewed lightwell allows daylight to enter the building on every floor and gives the people working inside a great view of the city. The atrium also limits the amount of artificial light needed inside the building. Large glass windows and pleasant open spaces flooded with daylight contribute a comfortable and inviting work environment.

为了减少照明方面的能源使用，该建筑采用了一个被称为 “液体光 “的概念，它允许人工照明根据建筑内的活动和移动而平滑地变暗。这些策略加在一起，使得Powerhouse Brattørkaia的照明能耗只有同等规模的典型商业办公大楼的一半左右。

In order to reduce energy use on lighting, the building employs a concept called “liquid light”, which allows the artificial light to smoothly dim up and down according to the activity and movement in the building. Taken together, these strategies allow Powerhouse Brattørkaia to consume only about half the amount of energy for lighting than a typical commercial office building of comparable size would.

该建筑为各种商业租户提供办公空间，包括建筑和航运公司，同时也容纳了一个重要的公共项目。一层的咖啡馆和游客中心向特隆赫姆人民开放，作为学校团体和普通公众的教育资源。访客中心解释了电力公司的能源概念，并支持公众对未来可持续建筑战略的了解和讨论。

The building provides office spaces for a diversity of commercial tenants, including construction and shipping firms, while also housing a significant public program. A café and a visitor center at the ground floor are open to the people of Trondheim as an educational resource for school groups and the general public alike. The visitor center explicates the energy concept of the Powerhouse and supports public knowledge and discourse on sustainable building strategies for the future.

通风和加热技术。电力公司优先考虑建筑使用者的身体舒适度和福祉，其策略是平衡其对新鲜空气和热舒适度的关注与极端的能源效率。通风系统为室内空间提供舒适和清洁的空气，并适应特隆赫姆的温和湿润气候。办公室景观包含调节通风的供气技术装置。空气在靠近地面的地方以低速排出，而抽风则通过楼梯井的压制集中进行。此外，该建筑的结构系统由热质（低排放的混凝土）组成，通过天花板上的战略切口暴露出来。热量吸收和保留热量和冷量，有助于在不使用电力的情况下调节建筑内的温度。

Ventilation and Heating Technologies. The Powerhouse prioritizes the physical comfort and well-being of the building’s occupants with strategies that balance its focus on fresh air and thermal comfort with extreme energy-efficiency. The ventilation system provides pleasant and clean air to the indoor spaces and accommodates Trondheim’s mild and humid climate. The office landscape contains technical installations for air supply that regulate ventilation. The air is let out close to the floor at low speed, while the extraction takes place centrally by suppression in the stair shafts. Further, the building’s structural system consists of thermal mass – low-emission concrete – which is exposed through strategic cutouts in the ceiling. The mass absorbs and retains heat and cold and helps regulate the temperature in the building without using electricity.

Powerhouse Brattørkaia因其努力而获得了BREEAM杰出认证，这是世界领先的可持续发展评估方法对资产的环境、社会和经济可持续发展性能的最高排名。其解决方案支持《联合国气候变化框架公约》的《巴黎协定》，该协定致力于将全球温度上升限制在1.5摄氏度以内。

For its efforts, Powerhouse Brattørkaia has received the BREEAM Outstanding certification, the highest possible ranking by the world’s leading sustainability assessment method for an asset’s environmental, social and economic sustainability performance. Its solutions support the UNFCCC Paris Agreement that pursues efforts to limit the global temperature increase to 1.5 degrees Celsius.
