Erick van Egeraat-designed Energy Tower to supply electricity & heat power for Roskilde 

Yesterday, His Royal Highness Crown Prince Frederik officially inaugurated The Energy Tower in Roskilde, Denmark, designed by Erick van Egeraat. Taking waste materials from nine municipalities in the nearby area as well as select international locations, the plant will generate electricity and heat power for Roskilde through the process of incineration.

Erick van Egeraat was selected for the project through a design competition in 2008 with a design that is sensitive to the flat landscape of the Roskilde area. The façade is comprised of two layers: an inner layer that provides a climatic barrier; and a second skin composed of umber-hued aluminium plates decorated with laser cut circular holes.

“At night the backlight perforated façade transforms the incinerator into a gently glowing beacon - a symbol of the plant’s energy production,” explains the architect. “Several times an hour a spark of light will gradually grow into a burning flame that lights up the entire building. When the metaphorical fire ceases, the building falls back into a state of burning embers.”

Lighting elements located between the two façade layers enable this illuminated performance, creating a spectacle for local people. The light is reflected onto the inner façade which enables the light to glow through the perforated skin. Given the flat landscape of the site, it was of great importance that the design be sensitive to the location as it is an outstanding structure in this otherwise low-rise area.   

Roskilde is also home to the UNESCO World Heritage Cathedral. In reference to this, Erick van Egeraat considers: “Although almost 1,000 years apart, the Cathedral’s twin towers made of warmly coloured stone and brick ánd the new iconic glowing incinerator, have now together become the novel guardians of the city’s otherwise modest presence in the Skagerrag landscape. Of course I am proud of that.”
