52|PROTAGONISTA kilometers long with 4 pylons of 185m high), realized in 2004, was one of the most complex lighting project for our studio, because we had simply to design and calculate everything just theoretically because the bridge construction was not yet started. And the client wanted a lighting visible from 10 kilometers away but without any glare or disturbances for the pedestrians walking on the bridge. In interior lighting, when we designed the lighting for the new car’s presentation room of the Peugeot Citroën design center, realized in 2005, the client ask us an average lux level of 2500, with a uniformity closed to 1 and without any shadows on the floors in a totally blind room of almost 1.000 m2. That was really a challenge and we did it we success. It was the first time for us that lighting was studied before the architecture and that the lighting was the starting point of the architectural design. It was a fantastic but also a very scary adventure. But I could list many others lighting projects, because when we design in our studio, we try to never reproduce something we already done and this make things more complex to realize but also more interesting and challenging for us. At the Ibero-American Meeting of Lighting Designers (EILD 2014) you spoke of a new tendency: the “black infrastructure”. What is it about? The black infrastructure is a new layer in a lighting master plan to study, to define and then to preserve zones of darkness in the urban environment. This dark infrastructure completes and matches with the green and blue infrastructures studied for cities. They allowed us to master at night (and hopefully to reduce) light pollution as well as to help protecting nocturnal biodiversity. These zones of darkness are defined according to citizens nocturnal uses studied at the city scale and developed in terms of nocturnal territories and night temporalities. The city of Rennes in the West of France was the first one in 2012 to approve that new black infrastructure Muristan square, Jerusalem, Israel Lighting design : Roger Narboni, CONCEPTO © CONCEPTO & Zhongtai NOCTURNAL LANDSCAPE AND URBAN LIGHTING DESIGN Roger Narboni founded in 1987, the “CONCEPTO” studio, dedicated to the design of urban lighting, landscape and architectural projects at large scales. All through these years, he has designed more than 120 lighting master plans for cities and neighborhoods in France and all over the world. He is a permanent member of the Administrative Council of the As- sociation of Lighting Designers of France (ACE) and a member of the Professional Lighting Designers Association (PLDA) since 2005. In 2008 he started Concepteurs Lumières sans Frontières, an associa- tion that he presided for 4 years. He has taught several international workshops on nocturnal landsca- pe and urban lighting desing in France, Italy, Colombia and Iran and he is the author of various publications on this topic. strategy that we are now developing in details on specific zones. In 2008, you created Concepteurs Lumiéres sans Frontiéres, an association you presided for 4 years. What does it do? We help, working as pro bono professionals, very poor countries and cities to create lighting master plans and lighting projects. We also share our lighting design knowledge and we try to help the local designers and technicians to develop their own local lighting culture. We already had activities in Mali (for the study of the lighting master plan of the city of Bamako with 18 European lighting designers working together and 5 lighting projects realized), in the city of Amathole, South Africa, in collaboration with LUCI association, and since 3 years in the city of Port-au- Prince (Haiti) that was destroyed by a terrible earthquake. You have taught several international workshops on nocturnal landscape and urban lighting planning in France, Italy, Colombia and Iran. What advice do you give your students? Open your eyes at night, be very creative, work a lot, discover and study
