Copenhagen: From gasometer to knowledge centre

				
The disused gasometer in the Copenhagen suburb of Valby is to be transformed into a knowledge centre for sustainable technological solutions for the society of the future. This is the vision of JJW Architects, who want the gasometer to become a sustainable vertical community with public spaces, hanging gardens and flexible plateaux. No decision has yet been made as to whether the gasometer will be demolished or transformed, although the first steps have been taken to open the gasometer’s facade and make it more accessible.

				

			


    
On the edge of Valby Park in Copenhagen V stands one of the city's landmarks - a 108 metre-high cylindrical gasometer in traditional gas-blue. The structure once held 200,000 m³ of gas in one massive compartment. Natural light enters the gasometer at the top through biunique skylights, revealing the interior surface of the structure, which is rather like black mother-of-pearl. For 40 years, oil was pumped down the gasometer’s massive piston, leaving behind deposits which reflect the daylight. Architect Ole Hornbek of JJW Architects want to reuse and transform this industrial building. His vision is to transform the derelict former supplier of energy into a knowledge centre, where ideas and solutions can be nurtured to meet the greatest challenges of our time, - building a sustainable society.
The architects' vision is to create a vibrant vertical urban environment with a flexible interior that allows the place to change over time, just like any other part of a city. The old gasometer will function as an independent community, comprising homes, commercial operations, shops, public institutions, public meeting places and hanging gardens. The tower will be used every day by ordinary citizens, consumers, classes of schoolchildren, clubs and societies. The functions of the spaces will not determined beforehand, which means that new functions can come into play as the need arises.

The community will be a sort of development laboratory for future sustainable technologies and social solutions, and a place where pilot projects can be tried and tested. The Valby gasometer will be a base for Danish and international companies and research institutes which will be able to collaborate and share their knowledge. The gasometer will be a forerunner in the in the discussion about the future of the world. JJW Architects will implement and cultivate the latest sustainable technical and social solutions and integrate them into their rethink of the gasometer.
The architects envisage a transluminated tower with mossy panels on the north side and reflective solar cells facing south, east and west. The facade will be open to allowing the daylight and minimise the use of artificial light. At the same time, the facade will reveal what is going on inside the building. Hanging gardens and trees will provide shade in the summer, and a flexible climate screen will facilitate testing of new technologies and materials. The rejuvenated gasometer will have three different temperate zones which will help minimise energy consumption and ensure natural ventilation. The building will be carbon neutral and energy consumption will be optimised by using alternative energy sources, and the gasometer will also supply energy to the local area - solar power and geothermal heat, for example.

”Valby gasometer tells the tale of change from introverted industrialism to the new, extrovert era. It is actually that banal, involving a transformation from introversion and danger, where everything can explode, to the new era’s candour, networking, willingness to make mutual concessions and a belief in life.”(Ole Hornbek, JJW Arkitekter)


    
Key Learning Points
The renovation of old buildings for new purposes is not simply a sustainable way to recycle materials. Although reusing existing architecture makes great demands on creativity, by reason of the physical limitations and constraints, it also provides the potential to build on the structure's history and idiom.
The transformation of outstanding buildings helps to ensure that the architectural idiom of a city does not become mundane and two characteristic of the period but extends beyond its own time.
Process
The project was initiated in the autumn of 2008 by a group of architects at JJW Architects.
The gas for old is owned by Copenhagen Energy (Københavns Energi), and ownership is currently the subject of negotiations between Copenhagen Energy and the Municipality of Copenhagen.
Meetings are held at regular intervals with a local inhabitants, and tours of the building have been arranged to attract attention to the project.

Project Facts
The gasometer was built in 1965. It came into service in 1967 and was closed again in 2007.

It is 108 m high and has a volume of 200,000m3. 
Facts for Thought
For 40 years, the gasometer was full of lethal though vital fuel - a pre-requisite of the industrial era. Now the cities are faced by a new challenge - sustainability. The vision is for this large industrial, previously so dangerous space will be made accessible, open and bright. Now it is time for the gasometer to contain today's fuel - knowledge and ideas.
