danish firm BIG architects has won the international competition to design a new waste-to-energy
treatment plant on the outskirts of copenhagen, denmark. in an attempt to re-brand the idea and aesthetics
of the standard factory, 'amagerforbraending' gives a secondary function to the structure by adding
a public ski slope on to its roof.



in context


approaching the project not as an isolated object but an integrated feature of that site that is
economically, environmentally, and socially profitable, the factory considers the local context:
situated on an edge condition - factories on one side, housing on the other; the city of copenhagen
on one hand, the water and island of amager on the other - the location receives very few visitors
simply by the lack of identity and purpose the site possesses. the design of a factory-ski slope hybrid
aims to mobilize the architecture and intensify the relationship between the building and the city,
creating a destination in and of itself.



ski slope





by integrating the height of the smokestack into the overall form of the architecture, an artificial slope
is created. public connection is created by pushing down one corner of the building, associating the street
with the roof line/ski run. measuring a total distance of over 1,500 m, three different pistes are made
from the geometry of the roofscape.

access to the ski run is provided by an elevator shaft placed adjacent to the smokestack. facing inwards,
the ride allows skiers to peer into the activities of the factory. two large 'sky light' apertures in the roof
also provide a transparent look into the innerworkings of the waste treatment plant.

with the intention of raising awareness for sustainable energy, the design proposal includes
a modification to the smokestack that will release smoke rings into the sky. activated whenever
one ton of fossil CO2 is released, the signal will serve a communicative function and remind
the viewer of the impact of consumption. at night, a heat tracking laser light will project
a pie chart on the ring to display the actual quota of fossil CO2.

mechanisms for smoke ring

(upper left) when the piston pushes out smoke, the upper gate is open and the ring forms.
as the lower gate closes, surplus smoke enters the pressure compensation champer
(upper right) smoke is stored when the upper gate is closed. the lower gate opens and
the storage chamber starts to refill with smoke as the piston begins to rise. the pressure compensator extends.
(lower left) piston continues to rise, building pressure
(lower right) when the storage chamer is full, the upper gate is opened while the lower gate closes.
piston moves down to push the smoke ring out. the complete cycle takes around 30 seconds.
