At the beginning of December, the 14th World Architecture Festival (WAF) honored the project by Bjarke Ingels and Co. with the award in the category “Production, Energy and Recycling”. We present the project here.
The World Architecture Festival took place from December 1 to 3, 2021. This year, the award ceremony was held virtually. The jury, made up of illustrious personalities from the international architecture scene, awarded prizes to completed building projects and future plans. The CopenHill project by Danish firm BIG Architects won the World Building of The Year award. This makes it the best building project in the Production, Energy & Recycling category. The jury cited the outstanding handling of topics such as recycling and zero carbon as the reason for the award. Paul Finch, Program Director of the award, put it as follows: Thanks to CopenHill, people suddenly wanted an infrastructure project of this size in their immediate neighborhood. Normally, a waste incineration plant would be hidden away on the outskirts of the city wherever possible. Here, it becomes the flagship of a city. At the same time, CopenHill also inspires other designers to think of added social value in construction projects. CopenHill has achieved this in a unique way. BIG designed and built a waste incineration plant that is fun.
CopenHill, also known as Amager Bakke, is a power station built in 2017 in Copenhagen’s industrial area. BIG Architects and SLA Landscape Architects have created a rooftop leisure park on the roof surfaces. A ski slope, a hiking trail through trees and hedges and a climbing wall are all part of the unusual spatial program. The spatial requirements of the complex electricity and thermal power plant are partly responsible for the bulges in the mountain topography. The internal processes are barely perceptible from the outside. BIG concealed the technical systems behind a shiny metal shell. The stacked aluminum elements create an elegant yet exciting façade. On the one hand, light enters through the open spaces during the day. At night, on the other hand, light penetrates from the openings to the outside and the entire building shines like an oversized lantern. From the roof, users can also finally see inside the building. Tubes, boilers and stairs can be seen from a glass elevator. Technology, sustainability and fun go hand in hand at CopenHill.
All in all, it is a project of superlatives. Firstly, the power plant itself is 41,000 square meters in size. Secondly, the ski slope covers 9,000 square meters and is 490 meters long. It is also the highest artificial ski slope in the world. A climbing wall is installed on one side of the facade. At a height of 85 meters, it is the highest artificial climbing wall in the world. The total roof area of around 16,000 square meters is a park landscape above the city. At the same time, heat is absorbed and air particles are filtered.
Man-made green mountain
The actual operation of the building takes place underneath the artificial mountain landscape. Every year, 440,000 tons of waste are converted into energy here. Thanks to state-of-the-art exhaust gas filters, the plant is one of the cleanest in the world. The energy generated supplies 150,000 households with electricity and heat. The plant replaced an outdated incineration plant at the same location. Baunetz reported that according to the design, plants will also grow on the façade. In the long term, the entire power plant is to become a man-made green mountain.
Two years after completion, the 2021 award officially confirms the uniqueness of CopenHill. The jury honored CopenHill as the 14th building in the World Building of the Year category since the award was launched in 2008. The symbiosis of sustainable architecture, social added value and clean energy production was convincing. It all started with a crazy-sounding idea. But the unusual idea of a ski slope on a waste incineration plant was realized. Star architect Bjarke Ingels shows how the challenges of the future can be met with ingenuity and wit. The integration of the power plant not only into the urban silhouette, but also into the everyday leisure activities of Copenhageners is original. The combination of practicality and fun shows how cities can become denser and more liveable at the same time. It is a project that is exemplary for Copenhagen. The Danish capital wants to be climate-neutral by 2025. In doing so, the metropolis is seeking to merge sustainability and the integrative design of public spaces.
CopenHill as an example
Bjarke Ingels told the Süddeutsche Zeitung in 2019 that CopenHill is the architectural expression of something that would otherwise have remained invisible. He also calls Amager Bakke an expression of hedonistic sustainability. It is sustainable first and foremost because it serves the citizens. The ecological added value for the environment is also a logical step in this understanding. The globally active office repeatedly causes a stir with its construction projects. Futuristic visions on the one hand and a playful approach to sustainability issues on the other are hallmarks of BIG. They have led the office and its founder to fame. His projects often combine different functions and requirements. With this approach, he has had a decisive influence on the cityscape of Copenhagen in recent times. CopenHill is exemplary for Copenhagen. And it is exemplary for BIG. The World Building of the Year award now confirms that this approach is also recognized by the wider architectural scene as forward-looking and inspiring.
