  Title Exploring regional and urban clusters and patterns in Europe using satellite observed lighting Type Journal Article
  Year 2018 Publication Environment and Planning B: Urban Analytics and City Science Abbreviated Journal Environment and Planning B: Urban Analytics and City Science  
  Volume in press Issue Pages in press  
  Keywords Remote Sensing  
  Abstract (down) We explore regional and urban clusters and patterns in Europe by using satellite images of nighttime lights and by employing Exploratory Spatial Data Analysis. We map Defense Meteorological Satellite Program nighttime lights data onto the nomenclature of territorial units for statistics III, Local Administrative Units II and pixel (i.e. 1 km2 grid cell system of Europe) level and apply global and local statistics of spatial association. Under the assumption that nighttime light data are a good proxy for economic activity, the analysis at regional level shows that the regions of global cities and megacities and their surrounding areas are hot spots of high economic activity levels. The regional analysis also reveals the polycentric hierarchical structure of Europe. Using the case studies of the regions of London and Île-de-France, the analysis at the urban level reveals the different urban structure of these two global regions and identifies the functional urban areas of London and Paris.

  Title Historical perspective on the physics of artificial lighting Type Journal Article
  Year 2018 Publication Comptes Rendus Physique Abbreviated Journal Comptes Rendus Physique  
  Volume 19 Issue 3 Pages 89-112  
  Keywords History; Lighting  
  Abstract (down) We describe the evolution of lighting technologies used throughout the ages, and how the need for improvements was such that any new technology giving better and cheaper lighting was immediately implemented. Thus, every revolution in energy sources – gas, petrol electricity – was first put to large-scale use in lighting. We describe in some detail several “ancient” techniques of scientific interest, along with their physical limitations. Electroluminescence – the phenomenon by which LEDs directly convert electricity into light – was long thought to only be of use for indicators or flat panel displays supposed to replace the bulky cathode-ray tubes. The more recent uses of LEDs were mainly for street traffic lights, car indicators, small phone displays, followed by backlighting of TV screens. LED lamps for general lighting only emerged recently as the dominant application of LEDs thanks to dramatic decrease in cost, and continuous improvements of color quality and energy conversion efficiency.

  Title More-than-human media architecture Type Journal Article
  Year 2018 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Architecture; Lighting; Planning  
  Abstract (down) We consider some of the planetary conditions and global circumstances that both research and practice of media architecture are embedded within, such as climate change, pollution, resource consumption, and loss of biodiversity. While there has been a notable increase in emphasis on participation and engagement in design and use, with the aim to increase the involvement of diverse and often marginalised citizens, a human-centred approach to media architecture comes with its own set of problems. In this paper, we want to draw the attention of the media architecture community to the fallacy of human exceptionalism and anthropocentrism. We present a critical review of examples of media architecture projects and installations that question our understanding of urban space as separate from nature, and designed primarily for humans and just humans. Informed by studies in disciplines such as science and technology studies, critical geography, urban planning, and interaction design, we use insights derived from our review to discuss ways towards a more-than-human approach to media architecture. We conclude by proposing for discussion nascent design considerations for media architecture to go beyond the needs of just humans and to consider new ways to appreciate and cater for our broader ecological entanglements with plants, animals, and the environment at large.

  Title Sustainable Lighting Policies: The Contribution of Advertisement and Decorative Lighting to Local Light Pollution in Seoul, South Korea Type Journal Article
  Year 2018 Publication Sustainability Abbreviated Journal Sustainability  
  Volume 10 Issue 4 Pages 1007  
  Keywords Lighting; Regulation  
  Abstract (down) We carried out field measurements to determine the contribution of advertisement and decorative lighting to local light pollution in Seoul. We used the lighting limits set by the “Light Pollution Prevention Act”, which regulates light pollution, as measuring criteria. Our results show that both advertisement and decorative lighting are significant contributors to local light pollution in Seoul. Thirty percent of advertisement lighting measured in our study areas exceeded the legal limits. Moreover, we found that certain types of advertisement lighting are more likely to cause light pollution than the others. In addition, 73% of the decorative lighting found in our sample areas exceeded the legal limits. Based on our findings, we suggest that local light pollution policies establish a curfew time when all advertisement and decorative lighting must be completely turned off. Such an approach is essential in reducing lighting levels in outdoor environments. Furthermore, it lessens the burden on law enforcement personnel, who otherwise must ensure that advertisement and decorative lighting levels are kept within the legal limits. In light of the ongoing debate over the role of lighting in public well-being and the sustainability of cities, the present study provides a discussion on the status and management policy of light pollution caused by advertisement and decorative lighting.

  Title Randomized trial of polychromatic blue-enriched light for circadian phase shifting, melatonin suppression, and alerting responses Type Journal Article
  Year 2018 Publication Physiology & Behavior Abbreviated Journal Physiol Behav  
  Volume in press Issue Pages  
  Keywords Human Health  
  Abstract (down) Wavelength comparisons have indicated that circadian phase-shifting and enhancement of subjective and EEG-correlates of alertness have a higher sensitivity to short wavelength visible light. The aim of the current study was to test whether polychromatic light enriched in the blue portion of the spectrum (17,000K) has increased efficacy for melatonin suppression, circadian phase-shifting, and alertness as compared to an equal photon density exposure to a standard white polychromatic light (4000K). Twenty healthy participants were studied in a time-free environment for 7days. The protocol included two baseline days followed by a 26-h constant routine (CR1) to assess initial circadian phase. Following CR1, participants were exposed to a full-field fluorescent light (1x10(14) photons/cm(2)/s, 4000K or 17,000K, n=10/condition) for 6.5h during the biological night. Following an 8h recovery sleep, a second 30-h CR was performed. Melatonin suppression was assessed from the difference during the light exposure and the corresponding clock time 24h earlier during CR1. Phase-shifts were calculated from the clock time difference in dim light melatonin onset time (DLMO) between CR1 and CR2. Blue-enriched light caused significantly greater suppression of melatonin than standard light ((mean+/-SD) 70.9+/-19.6% and 42.8+/-29.1%, respectively, p<0.05). There was no significant difference in the magnitude of phase delay shifts. Blue-enriched light significantly improved subjective alertness (p<0.05) but no differences were found for objective alertness. These data contribute to the optimization of the short wavelength-enriched spectra and intensities needed for circadian, neuroendocrine and neurobehavioral regulation.
