New Coloroufull Bridge Illumination in Bratislava reduces energy consumption and CO2 footprint
Phase 1: Illumination of the “UFO” with RGB LED floodlights
The first phase involved upgrading the lighting on the highest part of the restaurant’s bridge with modern RGB LED spotlights. In addition to the standard white lighting, the restaurant’s “UFO” can also be illuminated with different colours. On ordinary days, the lighting is connected to the weather forecast service and displays the weather or warnings for more than 500,000 residents and visitors of Bratislava at regular quarter-hourly intervals. At the same time, this part of the lighting is used to express the support or affiliation of city residents on memorial or awareness days. For example, the bridge silhouette is colourfully illuminated on Autism Awareness Day or on the Day of Remembrance for the Fight against Cancer.
Phase 2: Replacement of the pedestrian bridge lighting
The second phase, completed in June 2022, consisted of a comprehensive replacement of the pedestrian bridge lighting on the Budapest side of the bridge. 285 outdated and energy-consuming luminaires with mercury vapour lamps and an output of 120 W were replaced with modern LED luminaires. These highly efficient luminaires with an input power of only 36 W save approximately 75,000 kWh of electricity annually, which corresponds to a reduction of the CO2 footprint by 12 tonnes. In addition to the ability to continuously change the light intensity, these luminaires also allow independent communication and control via cloud management system for each lamp. This also enables the creation of individual light scenes and images.
Replacing street lighting and significantly reducing the carbon footprint: What sounds like a small change can make a big difference: That is what the project in Bratislava proves to us once again. What adjustments can you make in your city to achieve more sustainable mobility?
