Cologne Cathedral shines in a new light from Easter

On Easter Sunday, the Cologne Cathedral will appear in a new light if the new LED lighting is officially switched on from 9:30 p.m. Representatives of the city of Cologne, the Church and the Rheinenergie energy company work together to mark this important event.

The old lighting, consisting of about 250 halogen beams, is replaced by around 700 energy-efficient LED lights. This should not only improve the lighting effect of the cathedral, but also reduce energy consumption by about 80 percent. The new lighting effects promote better visibility of the architectural three -dimensionality of the Gothic building, which is emphasized by cathedral architect Peter Füssenich.

Five years preparation for new lighting

The planning and implementation of the new lighting design are the result of five years of intensive cooperation between the city, RheinEnergie, the cathedral construction hut and the light planning office "Licht Art Licht". Mayor Henriette Reker, Dompropst Guido Assmann and the CEO of the Rheinenergie, Andreas Feicht, are also expected to celebrate the new LEDs.

The new lighting is not without controversy, since conservationists have expressed concerns about the possible negative effects on the wildlife, especially in light -sensitive species such as bats and owls. However, RheinEnergie makes it clear that the new system sets standards in terms of sustainability and nature conservation and reduces light emissions.

Sustainability and reduction of light pollution

According to the RheinEnergie, the lighting design is adjusted in such a way that the architecture of the cathedral is now accentuated and illuminated in a differentiated manner. These changes should also minimize light pollution, while the light color can be adjusted in warm tones in order to be better in harmony with the wildlife. In addition, the light intensity is significantly reduced after midnight to put the cathedral in a quieter state.

The old system had a power consumption of around 54 kilowatts, while the new lighting only needs about eleven kilowatts. This changeover saves about 63 tons of CO2 annually, which contributes to the more environmentally friendly design of the cathedral.
