Arraiolos wins Auroralia Award

9 January 2012 13.00 GMT


(France) - Portuguese village beats competition from Belgium, UK and Germany for presigious award for best sustainable urban lighting initiatives.

 

 

With no fewer than 19 nominees, the 2011 Auroralia Awards, jointly organised by LUCI and Schréder, was the most successful in its three years. Following lively discussions, the panel of independent judges composed of representatives from specialised press chose to give first prize to the village of Arraiolos (Portugal) with Nivelles (Belgium) and St. Helens (UK) picking up second and third prizes respectively. Remchingen in Germany received a special mention. The representatives of these four municipalities received their Auroralia Award on 8th December in Lyon at the official ceremony during the Lyon Light Festival.

In 2011, Arraiolos acquired the enviable status of being the first Portuguese village to draw up and implement a large scale project to light the historic centre of the village exclusively by LEDs. The old lighting system, made up of a disparate set of conventional luminaires equipped with discharge lamps, was completely replaced. The objective was threefold: to increase the level of lighting; offer better-quality lighting; and dramatically reduce energy consumption and CO2 emissions.

To achieve this, the local authorities worked with the lighting designers Eduardo Gonçalves and Rogério Oliveira from Eclipz Lighting Design based in Lisbon. In collaboration with Schréder Iluminação, they designed a luminaire equipped with 36 LEDs that was perfect for their project.

By diffusing a warm white light, the 401 Rivara luminaires - named in homage to one of the village's famous inhabitants, a writer and statesman of the nineteenth century - provide excellent colour rendition and a high degree of visual comfort. With energy savings of no less than 50% per luminaire, the new LED installation significantly reduces operating and maintenance costs.

To preserve the open character of the space around the Collégiale, an eleventh-century church in the heart of Nivelles, the local authorities decided to ban luminaires on poles. They gave priority to bollards and recessed luminaires as their discreet integration helps preserve the cultural heritage. By exploiting different levels of lighting, the installation structures the space and highlights the architectural treasures of the town centre. The new installation generates energy savings of 73% and stops the town from producing more than 26 tonnes of CO2 into the atmosphere each year.

Through various operations under the heading "Nivelles, cœur de Lumière" ("Nivelles, heart of Light"), the town promotes a social and environmental approach to light. A commitment that clearly pleased the members of the Auroralia judging panel!

Situated in the heart of the town, precisely where there is most commercial activity, the campus is home not only to educational facilities but also a sports hall, restaurants and public spaces.

Replacing the old sodium lamps, a new LED lighting system was installed on the college site and in the four main streets surrounding it in the Liverpool suburb of St. Helens, a town of 175,000 inhabitants.

The aim was to increase the level and quality of lighting while significantly reducing energy consumption. The new installation generates energy savings of 21% and fulfils several functions: light the space comfortably and efficiently, reduce crime, ensure traffic safety and stimulate economic activity.

In rewarding St. Helens, the judges wanted to acknowledge the positive impact of this project on the social, economic and environmental aspects of urban and student life.

With just under 12,000 inhabitants, Remchingen has made a significant commitment to future generations by converting all its luminaires equipped with 150W sodium lamps to 34W 28 LED luminaires. The intervention involved no fewer than 1,000 lighting units in all corners of the town. To reduce the investment and the time needed to install the new luminaires, the authorities retained the existing poles. The new installation provides a warm, white light and allows the town to cut its energy bill by 78%. Each year, Remchingen will thus reduce its CO2 emissions by 146 tonnes.

By giving the German town a special mention, the judges wanted to emphasise the massive economic and environmental impact of a global conversion to LED light sources as undertaken by Remchingen as part of its 'relighting' project.
