a lot of regulations, obligations and constraints: European norms, efficiency, energy consumption, very low budgets, lighting pollution, nocturnal biodiversity preservation, calculations, 3D models, specifications, maintenance issues, legal problems, etc. In order to fulfil all these expectations, a mix of lighting engineering and lighting design is nowadays a necessity in every lighting design studio. But the changes also concerned the recognition of our profession as lighting designer. When I started my profession in 1987, the role of the lighting designer was totally unknown to most of the actors of urban design (politics, clients, urban planners, architects, landscape architects, interior designers). Today, in France, in many competitions, and for most of the important urban projects, a lighting designer is required within a multidisciplinary team. And I would say also with a lot of pleasure that the discipline of Light Urbanism and the methodology of the Lighting Master Plan, which I invented in 1987, are nowadays both obvious and useful tools for many cities around the world. Roger Narboni is famous for his use of coloured light, especially red and blue, like in Eco-District Clichy Batignolles or Memorial Acte in Guadalupe. Do these colours have some peculiar meaning for you? I started my career as an artist, doing oil painting for 12 years (including 1 year in ancient paintings restauration). Then, I started to create monumental sculptures and art installations with industrial glasses and light effects. In 1987 I became a fulltime lighting designer dedicated to the urban and architectural field. The use of colours has thus always been both easy and a pleasure to me, and it is a technique that I mastered from the very beginning of my artistic start. I do not look for a peculiar meaning when I want to use colours. I try to find and match the colours I like and that will be, in my opinion, the most suitable for the ongoing lighting project. The way the eye perceives colours in the nocturnal urban environment is also very important to me. In some specific occasions, like for some lighting projects in China, we use some specific colours (like jade, blue-green or gold) that are suitable for symbolic purposes. Your projects range from Urban Design to Product Design. Which is more interesting or difficult to solve? I do have more freedom in urban design projects than in product design projects. In urban design, you need to adapt your lighting design work to the whole project and to make the future nocturnal uses possible. But you are the only one deciding for your lighting design. So, you can be very creative and fortunately you can directly see, at the end of the construction work, the end user reactions. Designing a product is driven by marketing issues, cost calculations, payback, industrial possibilities and the necessity of being very innovative compared to all existing products. So, you make a bet and have to be very convincing. In this case, you are not the person that will take the final decision to realize or to launch the product, and you do not know the end users. What I really like in product design is to imagine prospective strategies, to think the lighting products of the future in accordance with the cities nocturnal evolutions. There is a real lack of futuristic approaches in all lighting fixtures companies. The marketing managers are stuck with a 3 years business plan and they never have time to think about what could happen in the next 10 or 20 years. We should face these future needs if we want to be or to stay innovative. Your project philosophy is “dynamic lighting based on a chronobiological approach”. Could you explain it in more details? This is not really a philosophy. It is an approach that we launched for some specific urban projects that were lacking of natural light even during daytime, to be more tuned with people’s circadian rhythms within the urban lighting pedestrians’ perception. It is something we first developed for the Robert de Flers street lighting in Paris. In the future, I would like to develop more this new approach, expressing with urban lighting the possibilities of offering well-being pauses, anti-stress solutions or even dark- therapy occasions to the citizens at night within the public realm. It is impressive how as the anonymous Robert de Flers Street changed after your action. Could you tell us more about it? Located under the Parisian district called “Front de Seine”, it is a very atypical covered street that leads to the recently restored Beaugrenelle shopping mall. In addition to the district renovation, a part of this street was re-lighted in 2013. The goal was to create a real day and night internal street image, treating the entire space with a single tone warm white light with a very good colour rendering index. The sidewalks are illuminated using special custom lanterns, equipped with a perforated mask, which are installed right in front the building entrances. In addition, a colourful and dynamic lighting, based on a chronobiological approach, was conceived for the very special concrete underside structure of the vaults, giving this underground place a livelier dimension. The light on the vaults changes in intensity and colour in a continuous and imperceptible way during the day, adapting to human needs. In the morning, the street is lit in blue for its Non ricerco un signiﬁcato particolare quando uso il colore. Cerco di trovare e abbinare i colori che più amo e che penso essere i più adatti al progetto in corso I do not look for a peculiar meaning when I want to use colours. I try to ﬁnd and match the colours I like and that will be, in my opinion, the most suitable for the ongoing lighting project 44 LUCE 323 / LIGHTING DESIGNERS
