Here, the Arup description:
“In the past, the attitude of ‘the more light the better’ has led to a general abundance of light, especially in urban areas, but both light and darkness are equally important to our health and well-being,” said Florence Lam, global lighting design leader at Arup. “With the shift towards 24 hour cities, we should not aim to simply recreate the day at night, but instead, we need to carefully consider the role of night-time lighting. We need to design our cities to change depending on the time of night and the different usage patterns of the public realm after dark – articulating what we call the ‘different shades of night’.”
The report highlights that we need to make human centered night-time design a priority in urban development, and one that should be considered from the earliest planning stages. It proposes that night-time lighting should play a more active role in shaping sustainable cities that are more enjoyable, more sociable, safer, healthier and easier to get around.
“Night-time is fundamentally different from daytime,” said Leni Schwendinger, lighting designer and urbanist at Arup. “In many hotter climates, it provides the best conditions for people to use outdoor urban spaces. So it deserves its own design approach, and thinking harder and smarter about street lighting is a vital part of this.”
The report was collaboration between the Foresight + Research + Innovation and Lighting teams at Arup. Involving a range of internal and external experts.
Reference to “shades of night“.
At a moment when the entire world is being reshaped by new lighting technologies and new design attitudes, the longer history of urban lighting remains fragmentary. Cities of Light aims to provide a global framework for historical studies of urban lighting and to offer a new perspective on the fast-moving developments of lighting today.
I have been testing “nighttime design” as a descriptor for a new urban illumination fortified by expertise and input by fellow urbanists, urban designers, social researchers, geographers, economic consultants, landscape architects, just to name a few. In Cities of Light the phrase was committed to print for the first time.
